MySQL的错误日志文件的修改

重新指定MySQL的错误日志文件的路径和文件名

1、在配置文件中修改log-error

vi my.cnf

log-error=/mysql/my3310/log/master-error.log

2、启动实例

# /mysql/my3310/bin/mysqld_safe --defaults-file=/mysql/my3310/my.cnf &

[1] 9783

# 2019-02-25T02:05:24.406457Z mysqld_safe error: log-error set to '/mysql/my3310/log/master-error.log', however file don't exists. Create writable for user 'mysql'.

由于未能创建/mysql/my3310/log/master-error.log，实例未完成启动。因为MySQL的错误日志文件默认是在初始化中创建的。

4、手动创建/mysql/my3310/log/master-error.log，实例可以启动。

touch /mysql/my3310/log/master-error.log

chown mysql.mysql /mysql/my3310/log/master-error.log
