nginx的启动脚本
问题：在预编译安装nginx时候每次启动时都非常不方便，所以想了下写个nginx脚本在/etc/init.d目录下可实现service的方式启动、停止、重启这样就方便多了！
[root@cml init.d]# vim nginxd
#!/bin/bash
#chkconfig: 2345 20 80
prog="nginxd"
nginx_bin="/usr/local/nginx/sbin/nginx"
if [ -x $nginx_bin ]; then ##if语句判断是否存在nginx路径
echo "$nginx_bin is installled !"
else
echo -n "$nginx_bin not installed !"
exit 5
fi
start(){
echo -n "starting $prog:"
$nginx_bin -t ##测试nginx配置文件
a=$?
if [ $a -eq 0 ]; then ###if语句判断上一句是否执行成功
touch /tmp/nginx.pid ##创建一个nginx.pid文件后启动nginx
$nginx_bin
else
echo "please check your nginx config"
exit 10
fi
}
stop(){
echo -n $"stopping $prog:"
$nginx_bin -s stop ##停止nginx
a=$?
if [ $a -eq 0 ]; then ##判断执行上一句成功就删除nginx.pid文件输出信息
rm -rf /tmp/nginx.pid
echo "success stop nginx"
else
echo "check your nginx command"
exit 11
fi
}
case $1 in ##
start)
start
;;
stop)
stop
;;
reload|restart)
stop
sleep 2
start
;;
*)
echo "Usage:$0{start|stop|reload/restart}"
;;
esac
验证：
