####mysql###
注意:源码编译完mysql后,就不要再安装mariadb-server,不然源码的脚本会被覆盖掉
一 源码安装 mysql
使用cmake,make,make install命令,cmake的命令可以显示安装的进度的百分比
mysql 官网:www.mysql.com
软件包依赖性:
1 yum install -y gcc gcc-c++ make ncurses-devel cmake
2 tar zxf mysql-boost-5.7.17.tar.gz
3 cmake-DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql -DMYSQL_DATADIR=/usr/local/lnmp/mysql/data -DMYSQL_UNIX_ADDR=/usr/local/lnmp/mysql/data/mysql.sock -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all
**********************************************************************************************
#####参数说明##########
-DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql#安装目录
-DMYSQL_DATADIR=/usr/local/lnmp/mysql/data#数据库存放目录,注意该目录的路径要在安装目录的路径下
-DMYSQL_UNIX_ADDR=/usr/local/lnmp/mysql/data/mysql.sock#Unix socket 文件路径
-DWITH_MYISAM_STORAGE_ENGINE=1#安装 myisam 存储引擎,要是不想安装,只要将1写成0即可

4 make && make install
5 groupadd -g 27 mysql###创建mysql组###
6 useradd -u 27 -g 27 -s /sbin/nologin -M -d /usr/local/lnmp/mysql/data mysql###创建mysql用户###
7 cp support-files/my-default.cnf /etc/my.cnf###在/etc/my.cnf文件下有datadir和socket的路径,与源码编译时的路径不符,所以要将/etc/my.cnf文件用源码编译产生的配置文件覆盖。####

10 cd /usr/local/lnmp/mysql/support-files/
11 cp mysql.server /etc/init.d/mysqld###在企业六的版本里,服务的启动和停止脚本文件一般都是放在/etc/init.d/目录下,所以将mysql服务的脚本文件放在该目录下,通过/etc/init.d/mysqld startr就可以启动mysql服务###

由于ncurses-devel已经装过,(可用rpm -q ncurses-devel查看),因此是CMakeCache.txt文件的影响,cmake在编译的过程中,会产生缓存文件,当继续编译时,就会从刚才停下的地方继续编译,而刚才停下的地方就是出错的地方,因此要将该缓存文件删除
[root@server1 mysql-5.7.17]# rm -f CMakeCache.txt

####php####
一源码编译php
php下载软件网址:php.net
tar jxf php-5.6.20.tar.bz2
cd php-5.6.20
1 编译:./configure --prefix=/usr/local/lnmp/php --with-config-file-path=/usr/local/lnmp/php/etc --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-openssl --with-snmp --with-gd --with-zlib --with-curl --with-libxml-dir --with-png-dir --with-jpeg-dir --with-freetype-dir --with-gmp --with-gettext -enable-inline-optimization --enable-soap --enable-ftp --enable-sockets --enable-mbstring --enable-fpm --with-fpm-user=nginx --with-fpm-group=nginx --with-mcrypt --with-mhash
**********************************************************************************
####参数说明######
--prefix=/usr/local/lnmp/php###指定安装目录###
--with-config-file-path=/usr/local/lnmp/php/etc###指定php主配置文件的位置###
--with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd###php如果要使用到mysql,可以通过调用外部的mysql模块,也可以使用php原身带有的数据库驱动mysqlnd,但是调用外部模块,内存需求量更大,性能也不高,而调用原身具有的mysqlnd模块,性能可以提高40%,因此建议使用原身的mysqlnd模块####

****************************************************************************************
2 软件依赖性:取决于你编译时安装的模块的依赖性,此时的依赖软件有libmcrypt-2.5.8-9.el6.x86_64.rpm,libjpeg-turbo-devel-1.2.1-1.el6.x86_64,
net-snmp-devel,re2c-0.13.5-1.el6.x86_64.rpm,libxml2-devel ,curl-devel, jpeglib-devel,libpng-devel,freetype-devel,gmp-devel
3 make&&makeinstall
二 将nginx和php联系在一起
1 cd php-5.6.20
2 cp php.ini-production /usr/local/lnmp/php/etc/php.ini###将配置文件移到/usr/local/lnmp/php/etc/下,并且一定以要命名为php.ini
3 cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
4 chmod +x/etc/init.d/php-fpm
5 vim /usr/local/lnmp/php/etc/php.ini
内容:
date.timezone=Asia/Shanghai
6 cp /usr/local/lnmp/php/etc/php-fpm.conf.default /usr/local/lnmp/php/etc/php-fgm.conf
7 vim php-fpm.conf
内容:
pid = run/php-fgm.pid
8 /etc/init.d/php-fpm reload###使用的fastcgi,有后台进程,有自己的端口(:9000),因此可以直接reload###
9 vim ~/.bash_profile
内容:
PATH=$PATH:$HOME/bin:/usr/local/lnmp/mysql/bin:/usr/local/lnmp/php/bin
10 source ~/.bash_profile
11 netstat-antlp | grep :9000
12 vim /usr/local/lnmp/nginx/conf/nginx.conf
内容:
location / {
root html;
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 /scripts$fastcgi_script_name;
include fastcgi.conf;
13 vim /usr/local/lnmp/nginx/html/index.php
内容:
<?php
phpinfo()
?>
测试:
访问172.25.78.1可以看到php的信息页
三 nginx+php+mysql
client -- > nginx将所有的php的处理转发 --- > php-fpm(端口号为9000) --- > php-mysqlnd --- > mysql:3306 --- > nginx --- > client
部署论坛
1 网上下载一个论坛的压缩包并解压
unzip Discuz_X3.2_SC_UTF8.zip
2 less readme/readme.txt###查看论坛部署的方法###
3 mv upload/ /usr/local/lnmp/nginx/html/bbs###readme.txt中写的要上传upload到服务器###
4 cd /usr/local/lnmp/nginx/html/bbs/
5 chmod 777 config/ uc_client/ data/ uc_server/ -R###安装过程要将目录权限开启###
安装过程会碰到该问题:
数据库连接错误:php不能连接到数据库
解决:
在php的配置文件里指定数据库socket的位置
vim /usr/local/lnmp/php/php.ini
内容:
**************************************************************
mysqli.default_socket = /usr/local/lnmp/mysql/data/mysql.sock
pdo_mysql.default_socket= /usr/local/lnmp/mysql/data/mysql.sock
mysql.default_socket = /usr/local/lnmp/mysql/data/mysql.sock
**************************************************************
/etc/init.d/php-fpm reload
还会碰到由于权限而无法连接数据库:
Permission denied
解决:
chmod 755 /usr/local/lnmp/mysql/data/
###php功能模块的扩展###
client -- > nginx将所有的php的处理转发 --- > php-fpm(端口号为9000) --- > php-mysqlnd --- > mysql:3306 --- > nginx --- > client
memcache
它是一个高性能的分布式的内存对象缓存系统,通过在内存里维护一个统一的巨大的 Hash 表,能够用来存储各种格式的数据。可以类比于 MySQL 这样的服务,而 PHP 扩展的 Memcache 实际上是连接Memcache 的方式,一般的使用目的是,通过缓存数据库查询结果,减少数据库访问次数,以提高动态web应用的速度,提高可扩展性。
可通过php -m | grep memcached 查看是否有memcached模块,php -m显示所有的php编译的模块,如果没有就要通过phpize添加该功能模块。
phpize官方说明:是用来扩展php扩展模块的,通过phpize可以建立php的外挂模块。
******************************************************************************************
使用phpize扩展memcached模块的步骤:
1 下载网址 http://memcached.googlecode.com/
tar zxf memcache-2.2.5.tgz
2 cd memcache-2.2.5
3 phpize(我已经将路径加入到~/.bash_profile文件下,如果没有加入的要用绝对路径)
****************************************
可能出现的问题:
Cannot find config.m4.
解决:
是因为你没有cd到memcache-2.2.5目录下
***************************************
4 ./configure
5 make && make insall
6 vim /usr/local/lnmp/php/etc/php.ini
内容:(配置文件里有说明添加扩展模块怎么写,模仿着写)
extension=memcache.so
7 /etc/init.d/php-fpm reload
*******************************************************************************************
可能出现reload服务后仍然没有memcache的情况,这时要检查你使用的是系统带有的rpm包,还是源码编译的包,如果是系统的rpm包则要先把系统的包删除,然后就可以了
[root@server1 etc]# which php
/usr/bin/php
[root@server1 etc]# rpm -qa|grep php
php-cli-5.3.3-26.el6.x86_64
php-common-5.3.3-26.el6.x86_64
php-5.3.3-26.el6.x86_64
[root@server1 etc]# rpm -e `rpm -qa|grep php`
[root@server1 etc]# source ~/.bash_profile
[root@server1 etc]# which php
/usr/local/lnmp/php/bin/php
[root@server1 etc]# php -m |grep mem
memcache
******************************************************************************************
###往mecache里存信息###
[root@server1 ~]# telnet localhost 11211
Trying ::1...
Connected to localhost.
Escape character is ‘^]‘.
set name 0 0 6###第二个0指不过期,如果是10,则指10后过期,6指的是存的字符数为6####
westos

get name
VALUE name 0 6
westos
END
delete name
DELETED
get name
END
###openresty###
nginx本身具有高并发的特点,如果将缓存放在php后面,则客户请求发给nginx,nginx给php-fpm处理,然后缓存到memcache上,则nginx就要等待php-fpm的处理结束,那么就会影响到ngnix本身的效率,但是,如果把memcache放在nginx之后,客户请求过来,如果缓存里有,就可以直接从memcache中取来发给客户端,而不用再等php-fpm,因此就不会影响到nginx的效率,将缓存放在nginx之后需要memc和srcache模块,此实验直接安装openresty做更方便。
openresty是一个全功能的web服务器。他打包了标准的nginx核心,很多的常用的第三方模块,以及他们大多数的依赖项。(来自官网)
vim /usr/local/openresty/nginx/conf/nginx.conf
内容:
upstream memcache {
server 127.0.0.1:11211;
keepalive 512;
}
location /memc {
internal;
memc_connect_timeout 100ms;
memc_send_timeout 100ms;
memc_read_timeout 100ms;
set $memc_key $query_string;
set $memc_exptime 300;
memc_pass memcache;
}
location ~ \.php$ {
set $key $uri$args;
srcache_fetch GET /memc $key;
srcache_store PUT /memc $key;
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi.conf;
}
具体过程如下:
[root@server1 ~]# tar zxf openresty-1.11.2.3.tar.gz
[root@server1 ~]# cd openresty-1.11.2.3
[root@server1 openresty-1.11.2.3]# ls
