centos7 安装 mysql 卡住了,输入: sudo systemctl start mysqld 后, 光标停在那里一动不动

参考的教程: https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-centos-7 https://linode.com/docs/databases/mysql/how-to-install-mysql-on-centos-7/

环境:cetnos7,openresty,已经安装好了 php7,infophp 也显示正常,之前安装了 mariadb,卸载了,现在安装 mysql5.5

执行命令的过程:

sudo yum install mysql-server

Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile

sudo systemctl start mysqld

(输入这个命令后,光标就卡在这里了)

请问具体的解决方案?

输入 sudo journalctl -xe -u mariadb.service
查看信息
然后输入:
/usr/bin/mysql_secure_installation
按照提示 输入 enter
然后输入 4 个 y
然后 sudo systemctl status mysqld
active 的状态
sudo systemctl start mysqld
成功

谢谢各位

之前卸载的时候,恐怕没有移除 /var/lib/mysql,mariadb-server 和 mysql-server 是默认相同的 db 文件位置。

建议 lnmp 一键安装

MySQL 启动日常
sudo systemctl start mysql --no-block; sudo journalctl -xefu mysql
这样一旦挂了你能知道发生了什么

@venpong 你那种一键安装是最容易出事的,因为你根本不知道它是咋运行的
