nginx 定时重启

1、编写脚本nginx_restart.sh

#!/bin/bash

ps -ef | grep nginx | grep -v grep > /data/nginx/nginx_restart.txt

file=$(cat /data/nginx/nginx_restart.txt | grep process | grep -v nginx_restart | awk '{print $2}')

file_num=`cat /data/nginx/nginx_restart.txt | grep process | grep -v nginx_restart| wc -l`

if [ $file_num -ge 1 ]
then
for i in $file
do
`kill -9 $i`
done

DATE1=`date +"%Y-%m-%d/%H:%M:%S"`

echo "nginx in $DATE1 stop!">> /data/nginx/nginx_restart.log

sleep 10

`/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf`

DATE2=`date +"%Y-%m-%d/%H:%M:%S"`

echo "nginx in $DATE2 start!" >> /data/nginx/nginx_restart.log
else
`/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf`
fi

2、添加计划任务

#每周6,3点30分执行一次

crontab -e ： 30 3 * * 6 sh /data/nginx/nginx_restart.sh
