Shell编写Nginx服务控制脚本
使用源码包安装的Nginx没办法使用"service nginx start"或"/etc/init.d/nginx start"进行操作和控制,所以写了以下的服务控制脚本。
可以使用的选项有:
start 启动
stop 停止
reload 重载
restart 重启
status 状态
test 检查配置文件
1、创建脚本文件并添加执行权限
# touch /etc/init.d/nginx # chmod +x /etc/init.d/nginx
2、编写脚本内容
#!/bin/bash # chkconfig: - 85 15 # description: Nginx server control script # processname: nginx # config file: /usr/local/nginx/conf/nginx.conf # pid file: /usr/local/nginx/logs/nginx.pid # # eastmoney public tools # version: v1.0.0 # create by XuHoo, 2016-9-14 # # source function library . /etc/rc.d/init.d/functions NGINX_NAME="nginx" NGINX_PROG="/usr/local/sbin/nginx" NGINX_PID_FILE="/usr/local/nginx/logs/nginx.pid" NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" NGINX_LOCK_FILE="/var/lock/subsys/nginx.lock" # check current user [ "$USER" != "root" ] && exit 1 start() { status if [[ $? -eq 0 ]]; then echo $"Nginx (PID $(cat $NGINX_PID_FILE)) already started." return 1 fi echo -n $"Starting $NGINX_NAME: " daemon $NGINX_PROG -c $NGINX_CONF_FILE retval=$? echo [ $retval -eq 0 ] && touch $NGINX_LOCK_FILE return $retval } stop() { status if [[ $? -eq 1 ]]; then echo "Nginx server already stopped." return 1 fi echo -n $"Stoping $NGINX_NAME: " killproc $NGINX_PROG retval=$? echo [ $retval -eq 0 ] && rm -f $NGINX_LOCK_FILE return $retval } restart() { stop sleep 1 start retval=$? return $retval } reload() { echo -n $"Reloading $NGINX_NAME: " killproc $NGINX_PROG -HUP retval=$? echo return $retval } status() { netstat -anpt | grep "/nginx" | awk '{print $6}' &> /dev/null if [[ $? -eq 0 ]]; then if [[ -f $NGINX_LOCK_FILE ]]; then return 0 else return 1 fi fi return 1 } _status() { status if [[ $? -eq 0 ]]; then state=`netstat -anpt | grep "/nginx" | awk '{ print $6 }'` echo $"Nginx server status is: $state" else echo "Nginx server is not running" fi } test() { $NGINX_PROG -t -c $NGINX_CONF_FILE retval=$? return $retval } case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) restart ;; status) _status ;; test) test ;; *) echo "Usage: { start | stop | reload | restart | status | test }" exit 1 esac
3、将脚本添加到系统服务并设置开机启动
# chkconfig --add nginx # chkconfig --level 3 nginx on
4、测试脚本是否能够执行
运行命令: service nginx start 或 /etc/init.d/nginx start
