我正在尝试在Red Hat 7上启动mysql。我删除了maria db，并按照以下说明安装了mysql：

[root@abc ~]# ll /var/log | grep mysql -rw-r-----. 1 mysql mysql 0 May 12 16:01 mysqld.log
我查了另一个系统，权限和上面一样。 好的，我会尝试修复文件…
[root@abc ~]# chmod 777 /var/log/mysqld.log
现在重启..
[root@abc ~]# service mysql start
同样的错误，如上所述，我失去了我的chmod …
ll / var / log | grep mysql -rw -r —–。 1 mysql mysql 0 5月12日16:01 mysqld.log
Selinux处于宽容模式。
这可能是由于redhat bug＃ 1189131 ，之前的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。
