lnmp搭建过程

CentOS 7 下安装 Nginx

yum -y groupinstall "Development Tools"
yum -y install wget
yum install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel
yum -y install make gcc gcc-c++ gcc-g77 flex bison file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel libpng10 libpng10-devel gd gd-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devel libevent libevent-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel gettext gettext-devel ncurses-devel gmp-devel pspell-devel unzip libcap lsof


1.直接下载.tar.gz安装包，地址：https://nginx.org/en/download.html


2.使用wget命令下载（推荐）。

wget -c https://nginx.org/download/nginx-1.10.1.tar.gz

我下载的是1.10.1版本，这个是目前的稳定版。

解压

依然是直接命令：

tar -zxvf nginx-1.10.1.tar.gz
cd nginx-1.10.1
配置

其实在 nginx-1.10.1 版本中你就不需要去配置相关东西，默认就可以了。当然，如果你要自己配置目录也是可以的。
1.使用默认配置

./configure
2.自定义配置（不推荐）

./configure --prefix=/usr/local/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --pid-path=/usr/local/nginx/conf/nginx.pid --lock-path=/var/lock/nginx.lock --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_gzip_static_module --http-client-body-temp-path=/var/temp/nginx/client --http-proxy-temp-path=/var/temp/nginx/proxy --http-fastcgi-temp-path=/var/temp/nginx/fastcgi --http-uwsgi-temp-path=/var/temp/nginx/uwsgi --http-scgi-temp-path=/var/temp/nginx/scgi
注：将临时文件目录指定为/var/temp/nginx，需要在/var下创建temp及nginx目录

编译安装

make
make install
查找安装路径：

whereis nginx

启动、停止nginx

cd /usr/local/nginx/sbin/
./nginx 



[root@ecs-24--zhushaochuan sbin]# ./nginx 
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

问题描述：地址已被使用。可能nginx服务卡死了，导致端口占用，出现此错误。
解决方法：首先用lsof:80看下80端口被什么程序占用。lsof返回结果如下：
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 3274 root 6u IPv4 10664 0t0 TCP *:http (LISTEN)
nginx 3547 nginx 6u IPv4 10664 0t0 TCP *:http (LISTEN)
发现是nginx程序，所以我们把nginx服务k掉，重新启动服务。。命令如下:
kill -9 3274
kill -9 3547
或者 killall -9 nginx
从新载入配置文件启动 /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

二、修改配置文件


1、地下的配置文件没用的都删除

[root@ecs-24--zhushaochuan conf]# cat nginx.conf

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  ‘$remote_addr - $remote_user [$time_local] "$request" ‘
                      ‘$status $body_bytes_sent "$http_referer" ‘
                      ‘"$http_user_agent" "$http_x_forwarded_for"‘;

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  www.xiaowei_1.com;
        access_log  logs/baidu.access.log  main;
        location / {
            root   /web/baidu;
            index  index.html index.htm;
        }
    }

    server {
        listen       8084;
        server_name  www.xiaowei_2.com;
        access_log  logs/sina.access.log  main;
        location / {
            root   /web/sina;
            index  index.html index.htm;
        }
    }

    server {
        listen       8083;
        server_name  www.xiaowei_3.com;
        access_log  logs/sina.access.log  main;
        location / {
            root   /web/sing;
            index  index.html index.htm;
        }
    }

   
   
    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}







2、没有搭建本地DNS，就配置hosts解析文件，都是一样的效果
[root@ecs-24--zhushaochuan ~]# cat /etc/hosts
127.0.0.1 ecs-24--zhushaochuan
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1       localhost
117.78.44.225   www.xiaowei_1.com
117.78.44.225   www.xiaowei_2.com
117.78.44.225   www.xiaowei_3.com
117.78.44.225   www.xiaowei_4.com




3、配置html虚拟机文件


在根目录下创建这几个文件
/web/sig/index.html         sig 222222222
/web/sing/index.html             <h1>www.nihao.com</h1>
/web/baidu/index.html         <h1>www.baidu.com</h>
/web/sina/index.html             <h1>www.sina.com</h1>


4、很重要：
   设置防火墙，把80端口映射到 8081,8082,8083  ，8080不能用，因为nginx首页已经占用，而80    端口要占一个，

[root@localhost ]# /sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT      这句话非常重要，下面两句可以不执行，一定要多执行几次
[root@localhost ]# /etc/init.d/iptables save  
[root@localhost ]# /etc/init.d/iptables restart               ---如果不行，用下面的。
[root@ecs-24--zhushaochuan baidu]# systemctl restart firewalld
   至此，OK了，主机已可访问虚拟机的nginx服务。

下面可以不执行，好像是，不能访问，执行试试，也可以写到iptables配置文件里
iptables -A INPUT -p tcp -m tcp --dport 8084 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 8083 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 8081 -j ACCEPT




5、开始访问

5.1  http://117.78.44.225:80

www.baidu.com

5.2  http://117.78.44.225:8081

sig 222222222

5.3  http://117.78.44.225:8083

www.nihao.com

5.4  http://117.78.44.225:8084

www.sina.com



三、搭建mysql


http://www.jianshu.com/p/95a103add722

Centos 7.2 编译安装 MySQL 5.7.14

一、环境准备
1、查看系统版本
1
2
3
4
[root@lnmp ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[root@lnmp ~]# uname -r
3.10.0-327.28.2.el7.x86_64


2、卸载系统自带的mysql/mariadb数据库及boost旧版本
复制代码
rpm -qa | grep mysql
rpm -qa | grep mariadb
rpm -e --nodeps boost-system-1.53.0-25.el7.x86_64
rpm -e --nodeps boost-thread-1.53.0-25.el7.x86_64
rpm -e mariadb-libs-5.5.47-1.el7_2.x86_64
rpm -e --nodeps mariadb-libs-5.5.47-1.el7_2.x86_64
boost官网http://www.boost.org/ ，yum -y install boost boost-devel boost-doc安装的是boost1.53版本


3、准备安装文件
复制代码
[root@lnmp mysql]# ll
total 131096
drwx------ 10  501 games     4096 Aug 17 15:02 boost_1_59_0
-rw-r--r--  1 root root  83709983 Aug 13  2015 boost_1_59_0.tar.gz
drwxr-xr-x 37 7161 31415     4096 Aug 17 15:48 mysql-5.7.14
-rw-r--r--  1 root root  50517329 Aug 17 14:38 mysql-5.7.14.tar.gz


说明：mysql5.7系列指定boost版本为boost_1_59_0。
资源下载地址：
[root@snails ~]# wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
[root@snails ~]# wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.13.tar.gz



4、依赖包安装
yum -y install make gcc-c++ cmake bison-devel ncurses-devel libaio libaio-devel perl-Data-Dumper net-tools


二、安装boost/mysql
1、安装boost
1 tar xvf boost_1_59_0
2 cd boost_1_59_0
3 ./bootstrap.sh --with-libraries=system,filesystem,log,thread --with-toolset=gcc
4 ./b2 toolset=gcc cxxflags="-std=c++11"
5 ./b2 install --prefix=/usr/local/boost
#备注：上面红色字体的内容，参考如下配置；上面绿色字体内容代表使用c++11标准，编译的库要使用统一标准。不使用，去掉绿色字体内容。

#默认安装在/usr/local/lib目录下;头文件在/usr/local/include/boost目录下；install后面可以加参数 --prefix=/usr 来设置安装路径
#如果提示boost版本不对应则卸载boost安装对应版本boost

新建MySQL用户和用户组

[root@snails ~]# groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql

预编译



[root@snails ~]# tar -zxvf boost_1_59_0.tar.gz

[root@snails data]# md5sum mysql-5.7.13.tar.gz 

8fab75dbcafcd1374d07796bff88ae00  mysql-5.7.13.tar.gz

[root@snails ~]# tar -zxvf mysql-5.7.13.tar.gz

[root@snails data]# mkdir -p /data/mysql

[root@snails data]# cd mysql-5.7.13

[root@snails data]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DWITH_BOOST=../boost_1_59_0 -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_EMBEDDED_SERVER=1



编译安装

[root@snails mysql-5.7.13]# make -j `grep processor /proc/cpuinfo | wc -l`
#编译很消耗系统资源，小内存可能编译通不过make install

[root@snails mysql-5.7.13]# make install




三、配置mysql
1、创建用户，初始化数据库　
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql
 

2、授权mysql数据库目录
chown -R mysql:mysql /usr/local/mysql
 
3、初始化mysql数据库
/usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data/
 

4、拷贝配置文件,修改配置文件
复制代码,按照下面的修改一下，修改之后无法加载配置文件，没关系，可能编译有问题
 1 cp support-files/my-default.cnf /etc/my.cnf 
 2 [root@lnmp ~]# cat /etc/my.cnf
 3 # For advice on how to change settings please see
 4 # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
 5 # *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the
 6 # *** default location during install, and will be replaced if you
 7 # *** upgrade to a newer version of MySQL.
 8 [mysqld]
 9 # Remove leading # and set to the amount of RAM for the most important data
10 # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
11 # innodb_buffer_pool_size = 128M
12 character_set_server=utf8
13 init_connect=‘SET NAMES utf8‘
14 #skip-grant-tables
15 # Remove leading # to turn on a very important data integrity option: logging
16 # changes to the binary log between backups.
17 # log_bin
18 # These are commonly set, remove the # and set as required.
19 # basedir = .....
20 #datadir =  /usr/local/mysql/data
21 # port = .....
22 # server_id = .....
23 # socket = .....
24 # Remove leading # to set options mainly useful for reporting servers.
25 # The server defaults are faster for transactions and fast SELECTs.
26 # Adjust sizes as needed, experiment to find the optimal values.
27 # join_buffer_size = 128M
28 # sort_buffer_size = 2M
29 # read_rnd_buffer_size = 2M 
30 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 
31 [client]
32 default-character-set=utf8
复制代码

root@ecs-24--zhushaochuan www.test.com]# source /etc/my.cnf  -------------没关系，没有影响
bash: [mysqld]: command not found...



5、拷贝启动文件，并授权
1、cp support-files/mysql.server /etc/init.d/mysqld
2、chmod 755 /etc/init.d/mysqld
 
6 、启动数据库
　　
/etc/init.d/mysqld start


三、更改初始化生成的数据库密码
注：由于5.7版本会初始化设置密码，需要自己修改，跟之前的数据库版本更改方式不一样。
完整的更改MySQL密码的方式如下：

vim /etc/my.cnf 加入skip-grant-tables，免密码登录数据库


[root@ecs-24--zhushaochuan mysql-5.6.17]# cat /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
character_set_server=utf8
init_connect=‘SET NAMES utf8‘
skip-grant-tables                                                                 -------------加上这句话，免密登陆，登陆完再删掉。
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M 

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 
[client]
default-character-set=utf8


注：我这里注释掉是改完之后再演示的。

 
重启MySQL数据库
[root@lnmp ~]# /etc/init.d/mysqld restart    ----------或者service mysqld start
Shutting down MySQL.. SUCCESS! 
Starting MySQL. SUCCESS! 
 

登录数据，修改密码即可，注5.7的password字段改为authentication_string
MySQL
update mysql.user set authentication_string=password(‘pwd123‘) where user=‘root‘ ;


改完后，注释掉my.cnf里面的skip-grant-tables 这一行，重启MySQL登录验证即可，然后就可以登录数据库进行一些简单的操作了。

Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


四、编译安装php70

3.进入php目录

cd php-7.1.1/


4.安装依赖包


yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel



5.编译配置（如果出现错误，基本都是上一步的依赖文件没有安装所致）


编译前做一下这些，防止出错
[root@ecs-24--zhushaochuan ~]# cd /usr/local/
[root@ecs-24--zhushaochuan local]# mkdir php
[root@ecs-24--zhushaochuan 42]# mount
[root@ecs-24--zhushaochuan 42]# umount /run/user/42/gvfs

./configure --prefix=/usr/local/php --with-config-file-path=/etc --enable-fpm --with-fpm-user=nginx --with-fpm-group=nginx --enable-inline-optimization --disable-debug --disable-rpath --enable-shared --enable-soap --with-libxml-dir --with-xmlrpc --with-openssl --with-mcrypt --with-mhash --with-pcre-regex --with-sqlite3 --with-zlib --enable-bcmath --with-iconv --with-bz2 --enable-calendar --with-curl --with-cdb --enable-dom --enable-exif --enable-fileinfo --enable-filter --with-pcre-dir --enable-ftp --with-gd --with-openssl-dir --with-jpeg-dir --with-png-dir --with-zlib-dir --with-freetype-dir --enable-gd-native-ttf --enable-gd-jis-conv --with-gettext --with-gmp --with-mhash --enable-json --enable-mbstring --enable-mbregex --enable-mbregex-backtrack --with-libmbfl --with-onig --enable-pdo --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-zlib-dir --with-pdo-sqlite --with-readline --enable-session --enable-shmop --enable-simplexml --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --with-libxml-dir --with-xsl --enable-zip --enable-mysqlnd-compression-support --with-pear --enable-opcache


6.正式安装


make && make install

编译最后出现错误：collect2: error: ld returned 1 exit status

解决：
[root@ecs-24--zhushaochuan php-7.1.1]# make ZEND_EXTRA_LIBS=‘-liconv‘
[root@ecs-24--zhushaochuan php-7.1.1]# ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/
[root@ecs-24--zhushaochuan php-7.1.1]# make && make install



7.配置环境变量


vi /etc/profile

在末尾追加

PATH=$PATH:/usr/local/php/bin
export PATH


执行命令使得改动立即生效
source /etc/profile


8.配置php-fpm

cp php.ini-production /etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

[root@ecs-24--zhushaochuan ~]# find / -name php-fpm.conf.default
find: ‘/run/user/42/gvfs’: Permission denied
[root@ecs-24--zhushaochuan 42]# mount     看最后一行
[root@ecs-24--zhushaochuan 42]# umount /run/user/42/gvfs


cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm

cat
9.启动php-fpm

/etc/init.d/php-fpm start

错误：
Starting php-fpm [09-Aug-2014 00:45:40] ERROR: unable to bind listening socket for address ‘127.0.0.1:9000‘: Address 

already in use (98)
[09-Aug-2014 00:45:40] ERROR: FPM initialization failed
 failed


解决方法：

netstat -lntup | grep 9000

killall php-fpm

[root@www ~]# service php-fpm start
Starting php-fpm  done                            启动成功



下面的错误不用管，没有影响
[root@ecs-24--zhushaochuan www.test.com]# source /etc/php.ini     -----------------不用管，没有影响
bash: [PHP]: command not found...
-bash: /etc/php.ini: line 2: syntax error near unexpected token `;;‘
-bash: /etc/php.ini: line 2: `;;;;;;;;;;;;;;;;;;;‘

五、测试访问



[root@localhost ]# /sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT -----------------无法访问就执行这句话
root@localhost ]# /etc/init.d/iptables save  
[root@localhost ]# /etc/init.d/iptables restart
[root@ecs-24--zhushaochuan baidu]# systemctl restart firewalld


一、全部删了配置文件，赋值下面的。
root@ecs-24--zhushaochuan html]# cat /usr/local/nginx/conf/nginx.conf
events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  ‘$remote_addr - $remote_user [$time_local] "$request" ‘
                      ‘$status $body_bytes_sent "$http_referer" ‘
                      ‘"$http_user_agent" "$http_x_forwarded_for"‘;

server {
        listen 80;
        server_name www.test.com;
    charset    utf-8;
    location / {
    root /var/www/www.test.com;
        index index.php index.html index.htm;
        }
     
        location ~ \.php$ {
        root html;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /var/www/www.test.com$fastcgi_script_name;
            include fastcgi_params;
        }
    }
 
}

[root@ecs-24--zhushaochuan ~]# cd /var/www/www.test.com/
[root@ecs-24--zhushaochuan ~]#touch index.php
[root@ecs-24--zhushaochuan ~]#vi index.php

<?php
phpinfo();
?>


[root@ecs-24--zhushaochuan www.test.com]# chown -R 777 /var/www/www.test.com/


[root@ecs-24--zhushaochuan www.test.com]# vi /etc/hosts

127.0.0.1 ecs-24--zhushaochuan
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1       localhost
117.78.44.225    www.test.com


[root@ecs-24--zhushaochuan www.test.com]# curl http://117.78.44.225/index.php


二、测试mysql连接是否成功

[root@ecs-24--zhushaochuan ~]# cd /var/www/www.test.com/
[root@ecs-24--zhushaochuan ~]#touch index.php
[root@ecs-24--zhushaochuan ~]#vi index.php

[root@ecs-24--zhushaochuan www.test.com]# cat index.php 
<?php
       $conn=mysqli_connect("127.0.0.1","root","pwd123");
       if($conn){
         echo "连接mysql数据库成功";
       }else{
          echo "连接数据库失败";
       }
?>


[root@ecs-24--zhushaochuan www.test.com]# curl http://117.78.44.225/index.php
连接mysql数据库成功


报错：

原因：   centos php7怎么添加mysql支持

php7可以通过pod_mysql或者mysqli来开启mysql的支持php5中mysql扩展，在php7中已经不支持了。

一、正确做法

<?php
       $conn=mysqli_connect("127.0.0.1","root","pwd123");    注意mysqli_connect   多个i
       if($conn){
         echo "连接mysql数据库成功";
       }else{
          echo "连接数据库失败";
       }
?>



错误的


<?php
       $conn=mysql_connect("127.0.0.1","root","pwd123");    注意mysql_connect   少个i
       if($conn){
         echo "连接mysql数据库成功";
       }else{
          echo "连接数据库失败";
       }
?>
