CentOS 7 安装Nginx

1. 从Nginx 官网下载nginx-1.14.2.tar.gz

    [root@localhost ~]# wget http://nginx.org/download/nginx-1.14.2.tar.gz

2. 将已下载的Nginx压缩包解压

    [root@localhost ~]# tar -zxvf nginx-1.14.2.tar.gz

3. 安装Nginx依赖

    [root@localhost ~]# yum -y install pcre*
    [root@localhost ~]# yum -y install zlib*
    [root@localhost ~]# yum -y install openssl*

4. 进入解压目录进行编译安装

    [root@localhost ~]# cd nginx-1.14.2
    [root@localhost ~]# ./configure --with-http_ssl_module

5. 启动Nginx

    # 找到Nginx安装目录
    [root@localhost ~]# whereis nginx
    # 启动Nginx
    [root@localhost ~]# ./usr/local/nginx/sbin/nginx

6. 修改防火墙

    [root@localhost ~]# vim /etc/sysconfig/iptables

   增加如下规则启用80端口

    -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

7. 添加Nginx作为系统服务

    # 新增服务
    [root@localhost ~]# vim /etc/init.d/nginx

   插入以下内容：

    #!/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
   
    # 配置Nginx为本地安装目录
    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
   
    make_dirs() {
       # make required directories
       user=`$nginx -V 2>&1 | grep "configure arguments:.*--user=" | sed ‘s/[^*]*--user=\([^ ]*\).*/\1/g‘ -`
       if [ -n "$user" ]; then
          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
        fi
    }
   
    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
    esac

   授予执行权限

    [root@localhost ~]# chmod +x /etc/init.d/nginx

   然后就可以用服务的方式来操作nginx了

    [root@localhost ~]# service nginx start # 启动
    [root@localhost ~]# service nginx stop  # 停止
    [root@localhost ~]# service nginx restart   # 重启
    [root@localhost ~]# service nginx restart   # 重新载入配置
    [root@localhost ~]# service nginx status    # 查看状态
