1.公有云环境安全组调整
生产环境: MySQL Redis 仅内网连接<br /> 测试环境: 开放规则待沟通
2. 普通用户登陆
只读用户 readel 私钥登录
3.sshd安全相关

3.2 登陆方式采用key登陆
root readel单独私钥文件互不影响
ssh-keygen -t rsa (下载私钥文件)
vim /etc/ssh/sshd_config
RSAAuthentication yes
PubkeyAuthentication yes

chmod 600 /root/.ssh/authorized_keys
systemctl restart sshd.service
chmod 0600 pinpoint_syf
