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
