mysqld_safe error: log-error set to '/data/mysql/log/mysqld.log', however file don't exists. ERROR! The server quit without updating PID file (/usr/local/mysql/mysqld.pid)

 

touch mysql.log

 

 

mysql啟動報錯

報錯日志：

[root@mysql ~]# /etc/init.d/mysqld start
Starting MySQL.2020-12-15T12:00:26.431235Z mysqld_safe error: log-error set to '/data/mysql/log/mysqld.log', however file don't exists. Create writable for user 'mysql'.
ERROR! The server quit without updating PID file (/usr/local/mysql/mysqld.pid)

 

分析原因：

我的原因是因為沒有my.cnf配置文件，有my.cnf.bak，又創建一個my.cnf配置文件

log-error set to '/data/mysql/log/mysqld.log', however file don't exists指定目錄/data/mysql/log/看一下mysqld.log是否存在

再去數據庫查看錯誤日志存放路徑：mysql> show global variables like '%log_error%';

 

（通過log_error對應的路徑為./mysql.err看和配置文件路徑不一致）

正確應為：

 

 

解決方法：

在/data/mysql/log/目錄下創建mysqld.log文件

touch mysqld.log

 

chown mysql:mysql mysqld.log

 

殺掉mysqld進程

pkill -9 mysqld

 

 重啟mysqld(按照自己的啟動方式來)

/etc/init.d/mysqld restart
