shell语句编写nginx的启动脚本

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]#vimnginxd

#!/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

echo "please check your nginx config"

exit 10

}

stop(){

echo -n $"stopping $prog:"

$nginx_bin -s stop ##停止nginx

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"

echo "check your nginx command"

exit 11

case $1 in ##

start)

start

;;

stop)

stop

reload|restart)

sleep 2

start

*)

echo "Usage:$0{start|stop|reload/restart}"

;;

esac

验证：

[root@cml init.d]# service nginxd start

/usr/local/nginx/sbin/nginx is installled !

starting nginxd:nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] still could not bind()

[root@cml init.d]# service nginxd stop

stopping nginxd:success stop nginx

[root@cml init.d]# service nginxd restart

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
