安装准备环境

• nginx的编译需要c++，同时prce（重定向支持）和openssl（https支持）也需要安装。

  # 请顺序安装依赖
  yum install gcc-c++  
  yum -y install pcre*  
  yum -y install openssl*

• 下载需要安装的nginx版本
  到http://nginx.org/download/选择对应的版本进行下载，如nginx-1.9.9.tar.gz
  

  #下载
  [root@admin ~] mkdir nginx-source
  [root@admin ~] cd nginx-source
  
  [root@admin nginx-source] wget http://nginx.org/download/nginx-1.9.9.tar.gz
  [root@admin nginx-source] tar -zxvf nginx-1.9.9.tar.gz
  [root@admin nginx-source] ls
  nginx-1.9.9 nginx-1.9.9.tar.gz

编译安装

设置安装目录

[root@admin ~] cd nginx-source/nginx-1.9.9
[root@admin nginx-1.9.9] ./configure --prefix=/usr/local/nginx

执行安装

[root@admin nginx-1.9.9] make 
[root@admin nginx-1.9.9] make install

启动服务

进入到安装目录启动服务

[root@admin nginx-1.9.9] cd /usr/local/nginx/sbin

[root@admin sbin] ./nginx

添加启动服务

• 添加nginx为系统服务(service nginx start/stop/restart)

  • 在/etc/init.d/目录下编写脚本，新建名为nginx的文件然后把脚本代码粘贴进去

    #!/bin/sh 
    # 
    # nginx - this script starts and stops the nginx daemon 
    # 
    # chkconfig:   - 85 15 
    # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ 
    #               proxy and IMAP/POP3 proxy server 
    # processname: nginx 
    # config:      /etc/nginx/nginx.conf 
    # config:      /etc/sysconfig/nginx 
    # pidfile:     /var/run/nginx.pid 
    
    # Source function library. 
    . /etc/rc.d/init.d/functions 
    
    # Source networking configuration. 
    . /etc/sysconfig/network 
    
    # Check that networking is up. 
    [ "$NETWORKING" = "no" ] && exit 0 
    
    nginx="/usr/local/nginx/sbin/nginx" 
    prog=$(basename $nginx) 
    
    NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" 
    
    [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx 
    
    lockfile=/var/lock/subsys/nginx 
    
    start() { 
        [ -x $nginx ] || exit 5 
        [ -f $NGINX_CONF_FILE ] || exit 6 
        echo -n $"Starting $prog: " 
        daemon $nginx -c $NGINX_CONF_FILE 
        retval=$? 
        echo 
        [ $retval -eq 0 ] && touch $lockfile 
        return $retval 
    } 
    
    stop() { 
        echo -n $"Stopping $prog: " 
        killproc $prog -QUIT 
        retval=$? 
        echo 
        [ $retval -eq 0 ] && rm -f $lockfile 
        return $retval 
    killall -9 nginx 
    } 
    
    restart() { 
        configtest || return $? 
        stop 
        sleep 1 
        start 
    } 
    
    reload() { 
        configtest || return $? 
        echo -n $"Reloading $prog: " 
        killproc $nginx -HUP 
    RETVAL=$? 
        echo 
    } 
    
    force_reload() { 
        restart 
    } 
    
    configtest() { 
    $nginx -t -c $NGINX_CONF_FILE 
    } 
    
    rh_status() { 
        status $prog 
    } 
    
    rh_status_q() { 
        rh_status >/dev/null 2>&1 
    } 
    
    case "$1" in 
        start) 
            rh_status_q && exit 0 
        $1 
            ;; 
        stop) 
            rh_status_q || exit 0 
            $1 
            ;; 
        restart|configtest) 
            $1 
            ;; 
        reload) 
            rh_status_q || exit 7 
            $1 
            ;; 
        force-reload) 
            force_reload 
            ;; 
        status) 
            rh_status 
            ;; 
        condrestart|try-restart) 
            rh_status_q || exit 0 
                ;; 
        *)    
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}" 
            exit 2 
    
    esac

  • 执行配置生效

    chmod 755 /etc/init.d/nginx
    chkconfig --add nginx

  • 验证、重启服务

    service nginx reload

    

结束.ok.
