一直在linux上鼓捣,还没有完整在linux下配置过nginx服务器环境部署呢,这几天没什么事就部署了一下,遇到的问题也很多,现在把我的环境部署文档发出了,有什么问题大家可以一起讨论一下,希望大家采用后遇到问题多多沟通。
|| 安装所需各种依赖包
sudo -s
LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel
krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
1、编译安装PHP 5.2.14所需的支持库:
tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure --prefix=/usr/local
make
make install
cd ../
tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../
tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../
关于/etc/ld.so.conf:
这个文件记录了编译时使用的动态链接库的路径。
默认情况下,编译器只会使用/lib和/usr/lib这两个目录下的库文件
将自己可能存放库文件的路径都加入到/etc/ld.so.conf中是明智的选择
添加方法也极其简单,将库文件的绝对路径直接写进去就OK了,一行一个。例如:
/usr/X11R6/lib
/usr/local/lib
/opt/lib
ldconfig是什么?
它是一个程序,通常它位于/sbin下,供root用户使用。它的作用就是将/etc/ld.so.conf列出的路径下的库文件 缓存到/etc/ld.so.cache 以供使用,因此当安装完一些库文件,或者修改ld.so.conf增加新的库路径后,需要运行一下/sbin/ldconfig,使所有的库文件都被缓存到ld.so.cache中,如果没做,即使库文件明明就在/usr/lib下的,也是不会被使用的,结果编译过程中报错,缺少xxx库。 切记改动库文件后一定要运行一下ldconfig,在任何目录下运行都可以。
2、编译安装MySQL 5.5.3-m3
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.5.3-m3.tar.gz
cd mysql-5.5.3-m3/
./configure --prefix=/home/pubsrc/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg
make && make install
chmod +w /home/pubsrc/mysql
chown -R mysql:mysql /home/pubsrc/mysql/
cd ../
①、创建MySQL数据库存放目录
mkdir -p /home/pubsrc/mysql/data/
mkdir -p /home/pubsrc/mysql/logs/binlog/
mkdir -p /home/pubsrc/mysql/logs/relaylog/
chown -R mysql:mysql /home/pubsrc/mysql/
②、以mysql用户帐号的身份建立数据表:
/home/pubsrc/mysql/bin/mysql_install_db --basedir=/home/pubsrc/mysql --datadir=/home/pubsrc/mysql/data --user=mysql
③、创建my.cnf配置文件:
vi /home/pubsrc/mysql/my.cnf
输入以下内容:
[client]
#character-set-server = utf8
port = 3306
socket = /tmp/mysql.sock
[mysqld]
#character-set-server = utf8
replicate-ignore-db = mysql
replicate-ignore-db = test
replicate-ignore-db = information_schema
user = mysql
port = 3306

#log-slow-queries = /home/pubsrc/mysql/logs/slow.log
#long_query_time = 10
[mysqldump]
quick
max_allowed_packet = 32M
④、创建管理MySQL数据库的shell脚本:
vi /home/pubsrc/mysql/mysql
#!/bin/sh
mysql_port=3306
mysql_username="admin"
mysql_password="12345678"
function_start_mysql()
{
printf "Starting MySQL...\n"
/bin/sh /home/pubsrc/mysql/bin/mysqld_safe --defaults-file=/home/pubsrc/mysql/my.cnf 2>&1 > /dev/null &
}
function_stop_mysql()
{
printf "Stoping MySQL...\n"
/home/pubsrc/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 5
function_start_mysql
}
function_kill_mysql()
{
kill -9 $(ps -ef | grep ‘bin/mysqld_safe‘ | grep ${mysql_port} | awk ‘{printf $2}‘)
kill -9 $(ps -ef | grep ‘libexec/mysqld‘ | grep ${mysql_port} | awk ‘{printf $2}‘)
}
if [ "$1" = "start" ]; then
function_start_mysql
elif [ "$1" = "stop" ]; then
function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"
fi
⑤、赋予shell脚本可执行权限:
chmod +x /home/pubsrc/mysql/mysql
⑥、启动MySQL:
/home/pubsrc/mysql/mysql start
⑦、通过命令行登录管理MySQL服务器(提示输入密码时直接回车):
/home/pubsrc/mysql/bin/mysql -u admin -p -S /tmp/mysql.sock
⑧、输入以下SQL语句,创建一个具有root权限的用户(admin)和密码(12345678):
GRANT ALL PRIVILEGES ON *.* TO ‘admin‘@‘localhost‘ IDENTIFIED BY ‘12345678‘;
GRANT ALL PRIVILEGES ON *.* TO ‘admin‘@‘127.0.0.1‘ IDENTIFIED BY ‘12345678‘;
⑨、(可选)停止MySQL:
/home/pubsrc/mysql/mysql stop
3、编译安装PHP(FastCGI模式)
tar zxvf php-5.2.14.tar.gz
gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
cd php-5.2.14/
./configure --prefix=/home/pubsrc/php --with-config-file-path=/home/pubsrc/php/etc --with-mysql=/home/pubsrc/mysql --with-mysqli=//home/pubsrc/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib
--with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect
--enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --without-pear
make ZEND_EXTRA_LIBS=‘-liconv‘
make install
cp php.ini-dist /home/pubsrc/php/etc/php.ini
cd ../
4、编译安装PHP5扩展模块
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/home/pubsrc/php/bin/phpize
./configure --with-php-config=/home/pubsrc/php/bin/php-config
make
make install
cd ../
tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/home/pubsrc/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/home/pubsrc/php/bin/php-config
make
make install
cd ../
tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/home/pubsrc/php/bin/phpize
./configure --with-php-config=/home/pubsrc/php/bin/php-config --with-pdo-mysql=/home/pubsrc/mysql
make
make install
cd ../
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../
tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/home/pubsrc/php/bin/phpize
./configure --with-php-config=/home/pubsrc/php/bin/php-config
make
make install
cd ../
5、修改php.ini文件
手工修改:查找/home/pubsrc/php/etc/php.ini中的extension_dir = "./"
修改为extension_dir = "/home/pubsrc/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行,然后保存:
extension = "memcache.so"
extension = "pdo_mysql.so"
extension = "imagick.so"
再查找output_buffering = Off
修改为output_buffering = On
再查找; cgi.fix_pathinfo=0
修改为cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。
自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:
sed -i ‘s#extension_dir = "./"#extension_dir = "/home/pubsrc/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#‘ /home/pubsrc/php/etc/php.ini
sed -i ‘s#output_buffering = Off#output_buffering = On#‘ /home/pubsrc/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /home/pubsrc/php/etc/php.ini
sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /home/pubsrc/php/etc/php.ini
6、配置eAccelerator加速PHP:
mkdir -p /home/pubsrc/eaccelerator_cache
vi /home/pubsrc/php/etc/php.ini
按shift+g键跳到配置文件的最末尾,加上以下配置信息:
[eaccelerator]
zend_extension="/home/pubsrc/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/home/pubsrc/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
7、创建www用户和组,以及供blog.test.com和www.test.com两个虚拟主机使用的目录:
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www
8、创建php-fpm配置文件(php-fpm是为PHP打的一个FastCGI管理补丁,可以平滑变更php.ini配置而无需重启php-cgi):
在/home/pubsrc/php/etc/目录中创建php-fpm.conf文件:
rm -f /home/pubsrc/php/etc/php-fpm.conf
vi /home/pubsrc/php/etc/php-fpm.conf
输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):

9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为128(如果服务器内存小于3GB,可以只开启64个进程),用户为www:
ulimit -SHn 65535
/home/pubsrc/php/sbin/php-fpm start
注:/home/pubsrc/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。
三、安装Nginx 0.8.46

net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216

使配置立即生效:
/sbin/sysctl -p
六、在不停止Nginx服务的情况下平滑变更Nginx配置
1、修改/home/pubsrc/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:
/home/pubsrc/nginx/sbin/nginx -t
如果屏幕显示以下两行信息,说明配置文件正确:
the configuration file /home/pubsrc/nginx/conf/nginx.conf syntax is ok
the configuration file /home/pubsrc/nginx/conf/nginx.conf was tested successfully
2、平滑重启:
①、对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可:
/home/pubsrc/nginx/sbin/nginx -s reload
②、对于Nginx 0.8.x之前的版本,平滑重启稍微麻烦一些,按照以下步骤进行即可。输入以下命令查看Nginx主进程号:
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ‘ ‘ ‘{print $2}‘
屏幕显示的即为Nginx主进程号,例如:
6302
这时,执行以下命令即可使修改过的Nginx配置文件生效:
kill -HUP 6302
或者无需这么麻烦,找到Nginx的Pid文件:
kill -HUP `cat /home/pubsrc/nginx/nginx.pid`
七、编写每天定时切割Nginx日志的脚本
1、创建脚本/home/pubsrc/nginx/sbin/cut_nginx_log.sh
vi /home/pubsrc/nginx/sbin/cut_nginx_log.sh
输入以下内容:
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/home/pubsrc/nginx/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /home/pubsrc/nginx/nginx.pid`
2、设置crontab,每天凌晨00:00切割nginx访问日志
crontab –e
输入以下内容:
00 00 * * * /bin/bash /home/pubsrc/nginx/sbin/cut_nginx_log.sh
开启php.ini中的cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。
3,创建nginx启东脚本
vi nginxctl
输入一下内容
#!/bin/bash
BIN=/home/pubsrc/nginx/sbin/nginx
PID=/home/pubsrc/nginx/nginx.pid
case $1 in
start)
$BIN -c /home/pubsrc/nginx/conf/nginx.conf;
exit $?;
;;
stop)
kill $(cat $PID);
exit $?;
;;
reload)
kill -HUP $(cat $PID);
exit $?;
;;
rotate)
kill -USR1 $(cat $PID);
exit $?;
;;
port)
echo "Your port is $(( 4000 + $(id -u) ))";
;;
*)
echo "Usage: $0 {start|stop|reload|roate|port}";
exit 1;
esac
最后赋予可执行权限
chmod 777 nginxctl
CentOS系统上CentOS Memcached安装。
1.CentOS Memcached安装前需要先安装Libevent:
# curl -O http://www.monkey.org/~provos/libevent-1.4.9-stable.tar.gz
# tar zxf libevent-1.4.9-stable.tar.gz
# cd libevent-1.4.9-stable
# ./configure
# make
# make install
2.继续CentOS Memcached安装:
# curl -O http://www.danga.com/memcached/dist/memcached-1.2.7.tar.gz
# tar zxf memcached-1.2.7.tar.gz
# cd memcached-1.2.7
# ./configure
# make
# make install
3.CentOS Memcached安装接着在当前用户的.bash_profile中添加
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
4.CentOS Memcached运行
# memcached -m 512 -u nobody -vv
测试时候发现会出现以下错误信息:
“/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory”
错误的原因是未在系统中注册Libevent. 解决方法如下:
# vi /etc/ld.so.conf.d/libevent-i386.conf
在VI中输入以下一行内容:
/usr/local/lib/
最后不要忘了
# ldconfig
5.CentOS Memcached运行
# memcached -m 512 -u nobody -vv
<6 server listening
<7 server listening
<8 send buffer was 109568, now 268435456
<8 server listening (udp)
<9 send buffer was 109568, now 268435456
<9 server listening (udp)
CentOS Memcached运行正常。
以上介绍CentOS Memcached安装及运行检测。
1、启动Memcache 常用参数
-p <num> 设置端口号(默认不设置为: 11211)
-U <num> UDP监听端口(默认: 11211, 0 时关闭)
-l <ip_addr> 绑定地址(默认:所有都允许,无论内外网或者本机更换IP,有安全隐患,若设置为127.0.0.1就只能本机访问)
-d 独立进程运行
-u <username> 绑定使用指定用于运行进程<username>
-m <num> 允许最大内存用量,单位M (默认: 64 MB)
-P <file> 将PID写入文件<file>,这样可以使得后边进行快速进程终止, 需要与-d 一起使用
