# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) yum -y install mariadb-server mariadb # mysql -V mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1 /usr/bin/mysql_secure_installation Enter current password for root (enter for none): ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) Enter current password for root (enter for none): mysqladmin password newpassword mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)' Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists! 检查/ var / lib / mysql /

任何想法为什么会发生？ 以及如何解决
你得到的错误是：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
2是ENOENT ，或没有这样的文件或目录。 这意味着套接字不存在。 原因是MariaDB没有运行。 在运行mysql_secure_installation之前，您需要启动MariaDB。
systemctl start mariadb
