• 在centos下启动nginx出现Failed to start nginx.service:unit not found


    错误的原因就是没有添加nginx服务,所以启动失败。

    解决方法:

    1.    在/root/etc/init.d/目录下新建文件,文件名为nginx

      或者用命令在根目录下执行:# vim /etc/init.d/nginx    (注意vim旁边有一个空格)

     

    2.    插入以下代码 

    #!/bin/sh
    # nginx - this script starts and stops the nginx daemin
    #
    # chkconfig:   - 85 15
    
    # description:  Nginx is an HTTP(S) server, HTTP(S) reverse 
    #               proxy and IMAP/POP3 proxy server
    
    # processname: nginx
    # config:      /usr/local/nginx/conf/nginx.conf
    # pidfile:     /usr/local/nginx/logs/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"
    
    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
    
    }
    
    
    
    restart() {
    
        configtest || return $?
    
        stop
    
        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

     

    3. 用命令进入此目录

      # cd /etc/init.d

     

    4. 依此执行以下命令

    # chmod 755 /etc/init.d/nginx

    # chkconfig --add nginx   (注意add前面是两个短横线-)

     

    5. 开启nginx

    # service nginx start
