  • CentOS下安装Nginx

    一、安装Nginx准备:

    1、yum -y install pcre* #将所有的pcre安装包安装上,需连网

    2、下载nginx安装包

    下载地址:http://nginx.org/en/download.html

    二、安装:

    1、解压nginx-xxx.tar.gz包

    命令:tar -xvf nginx-xxx.tar.gz

    2、进入解压包

    命令:cd nginx-xxx

    3、进行安装

    命令:./configure --prefix=/usr/local/nginx-1.9 --with-http_stub_status_module

    加入--with-http_stub_status_module是为了后面负载做准备

    4、修改配置

    命令:vim /usr/local/nginx/conf/nginx.conf,修改servername这里的服务器名称,先修改为自己的IP地址

    5、启动

    命令:/usr/local/nginx/sbin/nginx

    6、将防火墙关闭

            关闭命令:  service iptables stop 
            永久关闭防火墙:chkconfig iptables off

    7、验证结果

    在浏览器上输入 http://sername 回车,看是否存在welconme nginx页面,是,表示安装成功

    三、配置服务

    nginx如果每次用脚本启动,比较麻烦,喜欢使用脚本,所以,特意添加nginx添加到service中的脚本,vim /etc/rc.d/init.d/nginx

    该配置代码由官网提供,地址:https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/

    #!/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

    . /etc/rc.d/init.d/functions
    
    # Source networking configuration.
    . /etc/sysconfig/network
    
    # Check that networking is up.
    [ "$NETWORKING" = "no" ] && exit 0
    
    nginx="/usr/sbin/nginx"
    prog=$(basename $nginx)
    
    NGINX_CONF_FILE="/etc/nginx/nginx.conf"
    
    [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
    
    lockfile=/var/lock/subsys/nginx
    
    make_dirs() {
       # make required directories
       user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=([^ ]*).*/1/g' -`
       if [ -z "`grep $user /etc/passwd`" ]; then
           useradd -M -s /bin/nologin $user
       fi
       options=`$nginx -V 2>&1 | grep 'configure arguments:'`
       for opt in $options; do
           if [ `echo $opt | grep '.*-temp-path'` ]; then
               value=`echo $opt | cut -d "=" -f 2`
               if [ ! -d "$value" ]; then
                   # echo "creating" $value
                   mkdir -p $value && chown -R $user $value
               fi
           fi
       done
    }
    
    start() {
        [ -x $nginx ] || exit 5
        [ -f $NGINX_CONF_FILE ] || exit 6
        make_dirs
        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
    }
    
    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

    二。将shell脚本放入到 /etc/rc.d/init.d/中,并执行下列命令

    1:chmod +x /etc/rc.d/init.d/nginx (设置可执行权限)

    2:chkconfig --add nginx (添加系统服务)
