将两台MySQL数据库节点配置为主从
log-bin=mysql-bin #主节点开启二进制日志 binlog_format=mixed server-id = 1 #主节点server-id为1
授权从服务器复制账号并记录二进制日志位置：
server_id=2 #从服务器server-id为2 relay_log=relay-log #打开从服务器中继日志，并关闭二进制日志
从服务器连接主服务器，并打开复制线程：
查询从服务器连接状态：

主从复制测试：
在主节点创建数据库，并记录二进制日志位置：
在从节点查看：

实现SSL复制：
配置主服务器为CA:
[root@node6 CA]# (umask 077;openssl genrsa -out private/cakey.pem 1024) #将主节点配置为CA
[root@node6 CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3650
[root@node6 CA]# touch {index.txt,serial}
[root@node6 CA]# echo 01> serial生成主服务器证书：
[root@node6 CA]# mkdir /mysql/ssl -pv [root@node6 CA]# cd /mysql/ssl [root@node6 ssl]# (umask 077;openssl genrsa -out master.key 1024) [root@node6 ssl]# openssl req -new -key master.key -out master.csr [root@node6 ssl]# openssl ca -in master.csr -out master.crt -days 3650
生成从服务器证书：
[root@node8 ~]# mkdir /mysql/ssl -pv [root@node8 ~]# cd /mysql/ssl [root@node8 ssl]# (umask 077;openssl genrsa -out slave.key 1024) [root@node8 ssl]# openssl req -new -key slave.key -out slave.csr [root@node8 ssl]# scp slave.csr root@172.16.61.6:/tmp [root@node6 ssl]# openssl ca -in /tmp/slave.csr -out /tmp/slave.crt [root@node6 ssl]# scp /tmp/slave.crt root@172.16.61.8:/mysql/ssl/
拷贝CA证书到各节点：
[root@node6 ssl]# cp /etc/pki/CA/cacert.pem ./ [root@node6 ssl]# scp /etc/pki/CA/cacert.pem root@172.16.61.8:/mysql/ssl/
更改权限：
[root@node6 ssl]# chown -R mysql.mysql ./ [root@node8 ssl]# chown -R mysql.mysql ./
主从服务器配置SSL选项：（从服务器只需将文件名改为slave即可）
[mysqld] ssl ssl-ca = /mysql/ssl/cacert.pem ssl-cert = /mysql/ssl/master.crt ssl-key = /mysql/ssl/master.key
重启主节点查看ssl状态：
MariaDB [(none)]> SHOW GLOBAL VARIABLES LIKE "%SSL%"; +---------------+-----------------------+ | Variable_name | Value | +---------------+-----------------------+ | have_openssl | YES | | have_ssl | YES | | ssl_ca | /mysql/ssl/cacert.pem | | ssl_capath | | | ssl_cert | /mysql/ssl/master.crt | | ssl_cipher | | | ssl_key | /mysql/ssl/master.key | +---------------+-----------------------+
从节点：
MariaDB [(none)]> SHOW GLOBAL VARIABLES LIKE "%SSL%"; +---------------+-----------------------+ | Variable_name | Value | +---------------+-----------------------+ | have_openssl | YES | | have_ssl | YES | | ssl_ca | /mysql/ssl/cacert.pem | | ssl_capath | | | ssl_cert | /mysql/ssl/slave.crt | | ssl_cipher | | | ssl_key | /mysql/ssl/slave.key | +---------------+-----------------------+
主节点授权通过ssl连接的复制账号
MariaDB [(none)]> GRANT REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO ‘repluser‘@‘172.16.61.8‘ IDENTIFIED BY ‘replpass‘ REQUIRE SSL;
从节点ssl连接主节点测试：
[root@node8 ssl]# mysql -urepluser -preplpass -h172.16.61.6 --ssl-ca=/mysql/ssl/cacert.pem --ssl-cert=/mysql/ssl/slave.crt --ssl-key=/mysql/ssl/slave.key
主节点授权基于ssl复制的帐号：
