使用 dpkg -i 解压对应 deb包:

dpkg -i mysql-{common,community-client,client,community-server,server}_*.deb

4. 登录验证:

启动服务

systemctl start mysqld

root@ecs-df00:/home/dev# mysql -u root -p
mysql: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

安装 libncurses5 解决

sudo apt-get install libncurses5

root@ecs-df00:/usr/lib64# mysql -u root -p
Enter password: 

其中,mysql默认安装到 /etc/mysql 目录中
