yum仓库配置
# 安装仓库管理器
yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm -y
# 禁用mysql模组
yum module disable mysql -y安装pxc
# 安装pxc
percona-release enable-only pxc-80 release
percona-release enable tools release
yum install percona-xtradb-cluster -y初始化及配置
# 创建证书文件
mkdir -p /etc/mysql/certs/
mysql_ssl_rsa_setup -d /etc/mysql/certs/
# 将文件复制到集群所有节点的/etc/mysql/certs/目录，并设置所有者为mysql
scp /etc/mysql/certs/* 10.1.1.22:/etc/mysql/certs/
chown -R mysql:mysql /etc/mysql/编辑/etc/my.cnf

启动集群
# 启动初始化节点
systemctl start mysql@bootstrap.service初始化节点配置
# 查询密码
grep 'temporary password' /var/log/mysqld.log
# 初始化设置
mysql_secure_installation
# 登陆配置
mysql -u root -p
# select * from mysql.user where User='root' \G;
update mysql.user set Host='%' where User='root';
flush privileges;其他节点加入集群
systemctl start mysql集群查看 show status like 'wsrep_cluster%';
其他
# 安装percona-server
percona-release enable ps-80 release
# percona-release setup ps80
yum install percona-server-server
# 开启防火墙
firewall-cmd --add-port=3306/tcp --add-port=4444/tcp --add-port=4567/tcp --add-port=4568/tcp --permanent
