我正在尝试在Red Hat 7上启动mysql.

我按照以下说明删除了maria db并安装了mysql：

> service mysql start

Redirecting to /bin/systemctl start mysql.service

screen hangs here...

^C

[root@abc mysql]# service mysql status

Redirecting to /bin/systemctl status mysql.service

好,让我们看一下/ var / log / mysql

[root@abc ~]# ll /var/log | grep mysql

-rw-r-----. 1 mysql mysql 0 May 12 16:01 mysqld.log

我检查了另一个系统,权限与上面相同.

好的,我将尝试修复该文件…

[root@abc ~]# chmod 777 /var/log/mysqld.log

现在重新启动.

[root@abc ~]# service mysql start

与上述相同的错误,我丢失了chmod …

ll / var / log | grep MySQL的

-rw-r —– 1 mysql mysql 0 5月12日16:01 mysqld.log

Selinux处于许可模式.

解决方法:

这可能是由于redhat bug#1189131所致,先前的mariadb安装在后面留下了兼容性软链接：

尝试删除/var/log/mysqld.log并重新启动MySQL.
