1.生成CA自签名证书

mkdir /etc/my.cnf.d/sslcd /etc/my.cnf.d/sslopenssl genrsa 2048 > cakey.pemchmod 600 cakey.pemopenssl req -new -x509 -key cakey.pem -days 3650 -out cacert.pem

2.生成master私钥以及证书申请

openssl req -newkey rsa:2048 -days 365 -nodes -keyout master.key > master.csr

3.给master颁发证书

openssl x509-req-in master.csr -CA cacert.pem -CAkey cakey.pem-set_serial 01 > master.crt

4.生成slave私钥以及证书申请

openssl req -newkey rsa:2048 -days 365 -nodes -keyout slave.key > slave.csr

5.给slave颁发证书

openssl x509-req-in slave.csr -CA cacert.pem -CAkey cakey.pem -set_serial 02 > slave.crt

6.将证书文件分别分发给master和slave
Master:

Slave:

#修改/etc/my.cnf
#添加ssl等配置信息

创建从库复制用户，并仅允许通过ssl加密连接:

mysql> grant replication slave on *.* to 'repluser'@'192.168.1.%' identified by 'mysql' require ssl;

#修改/etc/my.cnf
#添加ssl等配置信息

配置连接主库的信息：

change master to master_host='192.168.1.2',master_user='repluser',master_password='mysql',master_log_file='mariadb-bin.000001',master_log_pos=245,master_ssl=1;start slave;show slave status\G
