环境：

ubuntu LTS 18.04.1

mysql  Ver 14.14 Distrib 5.7.29, for Linux (x86_64)

初探 linux，按照如下安装完mysql

sudo apt install mysql-server

sudo apt install mysql-client

sudo service mysql start

启动报错：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

放狗搜索，找了老半天也没解决。

最后，解决办法是：

# 切换到root

sudo -i

# 还是上面的启动 mysql 命令

service mysql start

# 终于出现了喜人的：

 * Starting MySQL database server mysqld
