安装 mysql
查看有没有安装MySQL：
dpkg -l | grep mysql
安装MySQL：
apt install mysql-server
netstat -tap | grep mysql
启动mysql 报错 su: warning: cannot change directory to /nonexistent: No such file or directory
Ubuntu
sudo service mysql stop
sudo usermod -d /var/lib/mysql/ mysql
sudo service mysql start
CentOS
sudo systemctl stop mysql.service
sudo usermod -d /var/lib/mysql/ mysql
sudo systemctl start mysql.service
原因:这种错误一般是 mysql 服务器异常关机导致的
MySQL在安装时会创建很多默认用户，其中就包含一个 debian-sys-maint，并且创建了该用户的随机密码，存储该用户信息的文件位于 /etc/mysql/debian.cnf文件中
启动 mysql service mysql start
查看线程是否启动 ：netstat -an | grep 3306 如果没有netstat配置，可以通过 ps -ef | grep mysql
查看配置文件 vim /etc/mysql/mysql.conf.d/mysqld.cnf 如果本机连接就不需要做本机解绑处理
移除 bind-address
登录mysql mysql -u root -p
show databases; 就可以查看当前的所有数据库。
更新 mysql user 权限信息
select user,host,plugin from user;
更新 mysql user 权限信息
ALTER USER ‘root’@‘%’ IDENTIFIED WITH mysql_native_password BY ‘123456’; 更新ROOT 本地密码为 123456
刷新 flush privileges；
