从头再来。旧的镜像在我安装gitlab之后Gitlab CE，现在远程登录相当慢。重新初始化了一下镜像。使用强密码策略。

• 0. 安装zsh+oh my zsh apt-get install -y zsh; sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
• 1. 安装Maven, git, java apt-get update; apt-get install -y maven git openjdk-8-jdk
• 2. 生成SSH public key ssh-keygen -t rsa -b 4096 -C "e@example.com" 并配置多个key ~/.ssh/config 内容如下
• 3. 安装mysql，how-to-install-mysql-on-ubuntu-18-04
• 4. 配置安全组策略，打开需要访问的端口。
