mysql 无意重启 [Note] /usr/sbin/mysqld: Normal shutdown
情况：
今早发现，昨天下午安装的4台mysql服务器，突然出现，由于在shell窗口
(root@localhost:mysql.sock) [(none)]> 190102 18:12:16 mysqld_safe mysqld from pid file /home/data/mysqldata/3306/data/mysql3.pid ended
什么情况，mysql意外关闭，4个shell窗口都出现了同样的错误，还是有点紧张，于是赶紧找error日志
[mysql@mysql3 scripts]$ tail -f -n 200 /home/data/mysqldata/3306/log/mysql-error.log

如上面的日志标记所示，4台都是一样，很奇怪为什么会发现这样的问题
系统：cpu 4核，内存18g，磁盘hdd 200g
[root@mysql3 ~]# cat /etc/redhat-release
Kylin Linux release 3.3.1707 (Core)
mysql version：
Server version: 5.6.15-log MySQL Community Server - (GPL)
刚安装好的机器，不应该出现这样的问题，但是除了我，又没有谁来搞这个mysql，看了 linux的history
[root@mysql3 ~]# export HISTTIMEFORMAT='%F %T '

没有相应时间的history
[root@mysql1 3306]# su - mysql

70 2019-01-03 08:38:15 cd ..
71 2019-01-03 08:38:17 cd 3306/log/
找不到问题，这时候开始网上找找，发现有一些人遇到这个问题
2019-01-02 18:09:56 3549 [Note] /usr/sbin/mysqld: Normal shutdown
但是回答的大部分都是，找找是否有history |grep mysqladmin 或者service mysqld stop等命令，看看是否手动或者其他的关闭了mysql
因为从error上看，是正常的关闭mysql服务
查看slow log也没有什么发现
还看到有一个帖子
有提到bug的帖子
https://bugs.mysql.com/bug.php?id=51081
由于还是找不到原因，寻思许久，不得解
这是问了一下开发同学 是否有重启过数据库，一问，才发现，他们悄悄的修改了my.cnf，然后同时重启了这4台机器。。。。。
哎，搞了半天，。。被开发的重启了，
这里警示了一个重要的问题，数据库就让dba团队来管控，开发只需要提出需求就好，而不是自己想当然的进行修改，，
按理说我们已经有 开发规范，管理规范，这种还是控制不住，毕竟。。。
