本文给大家分享的是如何给mysql配置SSL主从复制的具体方法,分别给出了5.6和5.7两个版本的实例,希望大家能够喜欢

MySQL5.6 创建SSL文件方法

官方文档:

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:

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 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 -h192.168.1.223 -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 -h192.168.1.223 -ptest -P3307 --ssl-mode=DISABLED   

(如该账号配置了require ssl 则无法登录)
