20190225 实验：实现基于SSL加密的主从复制

实验：实现基于SSL加密的主从复制
实验步骤：环境：三台主机，一台CA：200，一台master：150 ，一台slave：100
平时都是在CA上帮用户生成私钥，在服务器上做的
1 CA,master,slave 的证书相关文件
mkdir /etc/my.cnf.d/ssl
cd /etc/my.cnf.d/ssl
openssl genrsa 2048 > cakey.pem
openssl req -new -x509 -key cakey.pem -out cacert.pem -days 3650
给master 颁发证书
openssl req -newkey rsa:2048 -days 365 -nodes -keyout master.key > master.csr
openssl x509 -req -in master.csr -days 365 -CA cacert.pem -CAkey cakey.pem -set_serial 01 > master.crt
给slave 颁发证书
openssl req -newkey rsa:2048 -days 365 -nodes -keyout slave.key > slave.csr
openssl x509 -req -in slave.csr -days 365 -CA cacert.pem -CAkey cakey.pem -set_serial 02 > slave.crt

root@CA ssl]#ls /etc/my.cnf.d/ssl/
cacert.pem cakey.pem master.crt master.csr master.key slave.crt slave.csr slave.key

scp -r /etc/my.cnf.d/ssl master:/etc/my.cnf.d/

scp -r /etc/my.cnf.d/ssl slave:/etc/my.cnf.d/

1、150主机修改配置文件：加入“log_bin server_id=150” 100主机修改配置文件：加入“server_id=100 read_only”
