Nginx设置成服务并开机自动启动

在/etc/init.d下创建文件nginx

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

其内容参考nginx官方文档

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#

   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

              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

    return $retval
}

restart() {
    configtest || return $?
    stop
    sleep 1
    start
}

reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $prog -HUP
    retval=$?
    echo
}

force_reload() {
    restart
}

configtest() {

}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

    start)
        rh_status_q && exit 0

esac

需要注意的配置：

nginx=”/usr/local/nginx/sbin/nginx” //修改成nginx执行程序的路径。

NGINX_CONF_FILE=”/usr/local/nginx/conf/nginx.conf” //修改成nginx.conf文件的路径。

修改为自己自定义的路径：
nginx="/application/nginx/sbin/nginx"
NGINX_CONF_FILE="/application/nginx/conf/nginx.conf"

保存后设置文件的执行权限

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

至此就可以通过下面指令控制启动停止

/etc/init.d/nginx start
/etc/init.d/nginx stop

上面的方法完成了用脚本管理nginx服务的功能，但是还是不太方便。

先将nginx服务加入chkconfig管理列表：

[root@localhost ~]# chkconfig --add /etc/init.d/nginx

加完这个之后，就可以使用service对nginx进行启动，重启等操作了。

service nginx start
service nginx stop
service nginx restart

最后设置开机自动启动

[root@localhost ~]# chkconfig nginx on
