MySQL配置SSL主从复制-创新互联
MySQL5.6 创建SSL文件方法
官方文档：https://dev.mysql.com/doc/refman/5.6/en/creating-ssl-files-using-openssl.html#creating-ssl-files-using-openssl-unix-command-line
Create clean environment
mkdir /home/mysql/mysqlcerts && cd /home/mysql/mysqlcerts
Create CA certificate
openssl genrsa 2048 > ca-key.pem
openssl req -new -x509 -nodes -days 3600 -key ca-key.pem -out ca.pem
Create server certificate, remove passphrase, and sign it
server-cert.pem = public key, server-key.pem = private key
openssl req -newkey rsa:2048 -days 3600 -nodes -keyout server-key.pem -out server-req.pem
openssl rsa -in server-key.pem -out server-key.pem
openssl x509 -req -in server-req.pem -days 3600 -CA ca.pem -CAkey ca-key.pem -set_serial 01 -out server-cert.pem
Create client certificate, remove passphrase, and sign it
client-cert.pem = public key, client-key.pem = private key
openssl req -newkey rsa:2048 -days 3600 -nodes -keyout client-key.pem -out client-req.pem
openssl rsa -in client-key.pem -out client-key.pem
openssl x509 -req -in client-req.pem -days 3600 -CA ca.pem -CAkey ca-key.pem -set_serial 01 -out client-cert.pem
openssl verify -CAfile ca.pem server-cert.pem client-cert.pem
server-cert.pem: OK
client-cert.pem: OK
MySQL5.7 创建SSL文件方法
官方文档：https://dev.mysql.com/doc/refman/5.7/en/creating-ssl-rsa-files-using-mysql.html
mkdir -p /home/mysql/mysqlcerts
/usr/local/mysql-5.7.21-linux-glibc2.12-x86_64/bin/mysql_ssl_rsa_setup --datadir=/home/mysql/mysqlcerts/
主库创建SSL后进行配置
从库 192.168.1.222
mkdir -p /home/mysql/mysqlcerts
主库
chown -R mysql.mysql /home/mysql/mysqlcerts/
scp ca.pem client-cert.pem client-key.pem root@192.168.1.222:/home/mysql/mysqlcerts/
主库授权
GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.1.222' identified by '' require ssl;
主库 my.cnf
#SSL
ssl-ca=/home/mysql/mysqlcerts/ca.pem
ssl-cert=/home/mysql/mysqlcerts/server-cert.pem
ssl-key=/home/mysql/mysqlcerts/server-key.pem
restart mysql
从库
chown -R mysql.mysql /home/mysql/mysqlcerts/
my.cnf
ssl-ca=/home/mysql/mysqlcerts/ca.pem
ssl-cert= /home/mysql/mysqlcerts/client-cert.pem
ssl-key= /home/mysql/mysqlcerts/client-key.pem
创建复制：
change master to master_host='',master_user='',master_password='',master_log_file='mysql-bin.000001',master_log_pos=154, master_ssl=1, master_ssl_ca='/home/mysql/mysqlcerts/ca.pem', master_ssl_cert='/home/mysql/mysqlcerts/client-cert.pem', master_ssl_key='/home/mysql/mysqlcerts/client-key.pem' ,MASTER_CONNECT_RETRY=10;
验证：
主库配置SSL认证后，客户端默认以SSL方式登录
mysql -utest -h292.168.1.223 -ptest -P3307
(该账号不论是否配置require ssl 均能登录)
不以SSL方式登录命令为：
mysql -utest -h292.168.1.223 -ptest -P3307 --ssl-mode=DISABLED
(如该账号配置了require ssl 则无法登录)
