下文主要给大家带来mysql如何通过SSL实现主从复制,希望这些内容能够带给大家实际用处,这也是我编辑mysql如何通过SSL实现主从复制这篇文章的主要目的。好了,废话不多说,大家直接看下文吧。
实验环境:
node1:192.168.4.61
node2:192.168.4.62
CA:192.168.4.63
[root@node1~]#ntpdate 172.18.0.1
[root@node2~]#ntpdate 172.18.0.1
[root@node1~]#vim /etc/chrony.conf #node1和node2操作一样
[root@node1~]#systemctl start chronyd.service #启动服务
[root@node1~]#ssh-keygen
[root@node1~]#ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.4.62#将公钥复制到node2上
node2操作和node1操作相同。
node1和node2配置相同
[root@node1~]#vim /etc/hosts
3 192.168.4.61 node1 4 192.168.4.62 node2
[root@node1~]#yum install -y mariadb-server

(1)如果你已经正确的添加了证书,但是启动以后还是没有启动SSL功能,有可能没有权限
[root@node2~]#chown mysql.mysql -R /etc/mysql/ssl
(2)如果出现图片中的问题,停止slave即可
(3)每一个过程中都需要验证是否成功然后进行下面的操作。
