apc 缓存失效，重启php

ps axu|grep mysqld|grep -v mysqld_safe|grep -v grep |awk '{ print $2 }'|xargs kill

确认mysql 是否重启成功
如果杀不掉直接执行：
ps axu|grep mysqld|grep -v mysqld_safe|grep -v grep |awk '{ print $2 }'|xargs kill -9

/usr/local/webserver/php5_6_36/sbin/php-fpm -c /usr/local/webserver/php5_6_36/etc/php.ini -y /usr/local/webserver/php5_6_36/etc/php-fpm.conf
ps -ef |grep php-fpm |grep conf |awk '{print $2}' |xargs kill -USR2

解决方案：去redis数据目录，将aof文件备份，用redis-check-aof工具修复

[root@db redis]# cd /usr/local/redis/bin

[root@db redis]# cp appendonly.aof appendonly.aof.bak

[root@db redis]# redis-check-aof --fix appendonly.aof

0x c93488e5: Expected prefix '

AOF analyzed: size=3375772775, ok_up_to=3375663333, diff=109442

This will shrink the AOF from 3375772775 bytes, with 109442 bytes, to 3375663333 bytes

Continue? [y/N]: y
