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
