Nginx install and Add-module in centos

Nginx install and Add-module

############################
## 安装Nginx
############################

首先安装必要的库（nginx 中gzip模块需要 zlib 库，rewrite模块需要 pcre 库，ssl 功能需要openssl库）。选定/usr/local为安装目录，以下具体版本号根据实际改变。
1.安装PCRE库
$ cd /usr/local/
$ wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.38.tar.gz
$ tar -zxvf pcre-8.38.tar.gz
$ cd pcre-8.38
$ ./configure
$ make
$ make install

2.安装zlib库
$ cd /usr/local/ 
$ wget http://zlib.net/zlib-1.2.11.tar.gz
$ tar -zxvf zlib-1.2.11.tar.gz
$ cd zlib-1.2.11
$ ./configure
$ make
$ make install

3.安装ssl
$ cd /usr/local/
$ wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz
$ tar -zxvf openssl-1.0.1j.tar.gz
$ cd openssl-1.0.1j
$ ./config
$ make
$ make install

4.安装ngx_cache_purge
$ wget -c http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz
$ tar zxvf ngx_cache_purge-2.3.tar.gz

4.安装nginx
$ cd /usr/local/
$ wget http://nginx.org/download/nginx-1.9.9.tar.gz
$ tar -zxvf nginx-1.9.9.tar.gz
$ cd nginx-1.9.9  
$ ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_v2_module --with-ipv6 --with-http_sub_module --with-openssl=/usr/local/openssl-1.0.1j --with-pcre=/usr/local/pcre-8.38 --with-zlib=/usr/local/zlib-1.2.11 
$ --add-module=/usr/local/ngx_cache_purge-2.3
$ make
$ make install

5.查看版本
/usr/local/nginx/sbin/nginx -V

6.把Nginx加入service服务:
$ vi /ect/init.d/nginx
内容:
#!/bin/bash  
# nginx Startup script for the Nginx HTTP Server  
#  
# chkconfig: - 85 15  
# description: Nginx is a high-performance web and proxy server.  
# It has a lot of features, but it's not for everyone.  
# processname: nginx  
# pidfile: /var/run/nginx.pid  
# config: /usr/local/nginx/conf/nginx.conf  
nginxd=/usr/local/nginx/sbin/nginx  
nginx_config=/usr/local/nginx/conf/nginx.conf  
nginx_pid=/usr/local/nginx/nginx.pid  
 
RETVAL=0  
prog="nginx" 
 
# Source function library.  
. /etc/rc.d/init.d/functions  
 
# Source networking configuration.  
. /etc/sysconfig/network  
 
# Check that networking is up.  
[ ${NETWORKING} = "no" ] && exit 0  
 
[ -x $nginxd ] || exit 0  
 
 
# Start nginx daemons functions.  
start() {  
 
if [ -e $nginx_pid ];then 
   echo "nginx already running...." 
   exit 1  
fi  
 
   echo -n $"Starting $prog: " 
   daemon $nginxd -c ${nginx_config}  
   RETVAL=$?  
   echo  
   [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx  
   return $RETVAL  
 
}  
 
 
# Stop nginx daemons functions.  
stop() {  
    echo -n $"Stopping $prog: " 
    killproc $nginxd  
    RETVAL=$?  
    echo  
    [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid  
}  
 
 
# reload nginx service functions.  
reload() {  
    echo -n $"Reloading $prog: " 
    $nginxd -s reload  
    #if your nginx version is below 0.8, please use this command: "kill -HUP `cat ${nginx_pid}`" 
    RETVAL=$?  
    echo  
}  
 
# See how we were called.  
case "$1" in 
start)  
    start  
    ;;  
 
stop)  
    stop  
    ;;  
 
reload)  
    reload  
    ;;  
 
restart)  
    stop  
    start  
    ;;  
 
status)  
    status $prog  
    RETVAL=$?  
    ;;  
*)  
    echo $"Usage: $prog {start|stop|restart|reload|status|help}" 
    exit 1  
esac  
 
exit $RETVAL

############################
## Nginx 可能的错误
############################
1: nginx: [emerg] getpwnam(“www”) failed  （系统中没有www这个用户）
解决方案：
$ /usr/sbin/groupadd -f www
$ /usr/sbin/useradd -g www www

############################
## 添加Nginx第三方模块
############################

1.查看Nginx configure：
/usr/local/nginx/sbin/nginx -V

2.重新编译Nginx
$ ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_v2_module --with-ipv6 --with-http_sub_module --with-openssl=/usr/local/openssl-1.0.2j --with-pcre=/usr/local/pcre-8.38 --with-zlib=/usr/local/zlib-1.2.11 
$ --add-module=/usr/local/ngx_cache_purge-2.3

make

3.复制编译好的./objs/nginx替换掉/usr/local/nginx/sbin/下的nginx
service nginx stop

cp ./objs/nginx /usr/local/nginx/sbin/

service nginx start

4.查看结果：
/usr/local/nginx/sbin/nginx -V
