MySQL不停重启问题

MySQL不停的自动杀掉自动重启

看一下log日志  my.cnf 里配置的 log_error =/var/log/mysqld.log

vim /var/log/mysqld.log    

报的错误只是

[ERROR] Can't start server: Bind on TCP/IP port: Address already in use 

[ERROR] Do you already have another mysqld server running on port: 3306 ? 

除了MySQL自己的那个3306  其它没有进程有占用这个端口  MySQL自己一直在不停重启

网上搜了很多  其中看到 加上一行 innodb_force_recovery=4 可以先不让MySQL重启  试了不行  还是不停的重启

sudo /usr/local/mysql/bin/mysqld --console

查看发现 [ERROR] Can't find messagefile  ***

sudo vim /usr/local/mysql/my.cnf

加上一行 lc-messages-dir=/usr/local/mysql/share/

目录指定成mysql安装目录下的share目录

再启动MySQL 发现可以了 不一直自动重启了

访问站点发现表都是只读的  需要去掉my.cnf中配置的innodb_force_recovery=4 

 然后重启MySQL

然后MySQL正常运行了

正常运行后再 sudo /usr/local/mysql/bin/mysqld --console 看时  依然有[ERROR] Can't find messagefile ***

后面去掉my.cnf中的lc-messages-dir=/usr/local/mysql/share/ 这一行

再重启一下MySQL  发现MySQL还是正常的  

。。     先不纠结了
