教程开始

1：新建一个shell脚本执行以下代码
或者进面板 把以下代码丢到计划任务里的shell脚本执行

#!/bin/bash PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin export PATH stop_service(){         /etc/init.d/bt stop         if [ -f "/etc/init.d/nginx" ]; then                 /etc/init.d/nginx stop > /dev/null 2>&1         fi         if [ -f "/etc/init.d/httpd" ]; then                 /etc/init.d/httpd stop > /dev/null 2>&1         fi         if [ -f "/etc/init.d/mysqld" ]; then                 /etc/init.d/mysqld stop > /dev/null 2>&1         fi         if [ -f "/etc/init.d/pure-ftpd" ]; then                 /etc/init.d/pure-ftpd stop > /dev/null 2>&1         fi         if [ -f "/etc/init.d/tomcat" ]; then                 /etc/init.d/tomcat stop > /dev/null 2>&1         fi         if [ -f "/etc/init.d/redis" ]; then                 /etc/init.d/redis stop > /dev/null 2>&1         fi         if [ -f "/etc/init.d/memcached" ]; then                 /etc/init.d/memcached stop > /dev/null 2>&1         fi         if [ -f "/www/server/panel/data/502Task.pl" ]; then                 rm -f /www/server/panel/data/502Task.pl                 if [ -f "/etc/init.d/php-fpm-52" ]; then                         /etc/init.d/php-fpm-52 stop > /dev/null 2>&1                 fi                 if [ -f "/etc/init.d/php-fpm-53" ]; then                         /etc/init.d/php-fpm-53 stop > /dev/null 2>&1                 fi                 if [ -f "/etc/init.d/php-fpm-54" ]; then                         /etc/init.d/php-fpm-54 stop > /dev/null 2>&1                 fi                 if [ -f "/etc/init.d/php-fpm-55" ]; then                         /etc/init.d/php-fpm-55 stop > /dev/null 2>&1                 fi                 if [ -f "/etc/init.d/php-fpm-56" ]; then                         /etc/init.d/php-fpm-56 stop > /dev/null 2>&1                 fi                 if [ -f "/etc/init.d/php-fpm-70" ]; then                         /etc/init.d/php-fpm-70 stop > /dev/null 2>&1                 fi                 if [ -f "/etc/init.d/php-fpm-71" ]; then                         /etc/init.d/php-fpm-71 stop > /dev/null 2>&1                 fi         fi         swapoff /www/swap } stop_service

Copy

2：执行完后扩容好磁盘后重新挂载上去后执行以下两条命令

swapon /www/swap echo "True" > /www/server/panel/data/502Task.pl

Copy

3：最后别忘了启动宝塔服务

/etc/init.d/bt start
