架构图解
192.168.4.66
192.168.4.10
192.168.4.88
拷贝PXC软件到3台服务器
拷贝mysql-5.7.17.tar 软件到 pxcnode66 主机
• 把pxcnode66主机配置为mysql11的从服务器:
– 安装软件mysql-5.7.17.tar
– 修改配置文件 (指定server_id)
– 启动mysqld服务
– 确保数据一致
– 指定主服务器
– 查看状态信息 show slave
status\G;
[root@pxcnode66 ~]# tar -xvf mysql-5.7.17.tar
[root@pxcnode66 ~]# yum -y install mysql-community-*.rpm
[root@pxcnode66 mysql]# vim /etc/my.cnf
[root@pxcnode66 mysql]# systemctl start mysqld
[root@pxcnode66 ~]# grep password /var/log/mysqld.log
mysql> alter user root@"localhost" identified by"123qqq...A";
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye
确保数据一致
[root@mysql11 ~]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm
[root@mysql11 ~]# yum -y install percona-xtrabackup-24-2.4.7-1.el7.x86_64.rpm
[root@mysql11 ~]# innobackupex --user root --password 123qqq...A --slave-info /allbak --no-timestamp
[root@mysql11 ~]# scp -r/allbak root@192.168.4.66:/root/
[root@pxcnode66 ~]# cd PXC
[root@pxcnode66 ~]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm
[root@pxcnode66 ~]# yum -y install percona-xtrabackup-24-2.4.13-1.el7.x86_64.rpm
[root@pxcnode66 ~]# innobackupex --apply-log /root/allbak/
[root@pxcnode66 ~]# innobackupex --copy-back /root/allbak/
[root@pxcnode66 ~]# chown -R mysql:mysql /var/lib/mysql
[root@pxcnode66 ~]# systemctlstart mysqld
[root@pxcnode66 ~]# cat/root/allbak/xtrabackup_info | grepmaster11
mysql> change master to master_host="192.168.4.11" ,master_user="repluser" , master_password="123qqq...A" ,master_log_file="master11.000005" , master_log_pos=154;
mysql> show slave status\G" | grep -i 192.168.4.11
在pxcnode66主机,做如下配置:
– 停止mysqld服务、卸载mysqld服务软件
– 安装PXC软件、修改配置文件、启动mysql服务
– 数据库管理员登录、用户授权、查看状态信息
[root@pxcnode66 ~]# rpm -qa | grep -i mysql 一定要把查出来的包删干净了,不然是装不上包的
[root@pxcnode66 ~]# rpm -e --nodeps

[root@pxcnode66 PXC]# rpm -ivh qpress-1.1-14.11.x86_64.rpm
[root@pxcnode66 PXC]# tar -xvf Percona-XtraDB-Cluster-5.7.25-31.35-r463-el7-x86_64-bundle.tar
[root@pxcnode66 PXC]# yum -y install Percona-XtraDB-Cluster-*.rpm
[root@pxcnode66 PXC]# vim /etc/percona-xtradb-cluster.conf.d/mysqld.cnf

[root@pxcnode66 PXC]# vim /etc/percona-xtradb-cluster.conf.d/wsrep.cnf

[root@pxcnode66 PXC]# systemctl start mysql
[root@pxcnode66 PXC]# ss -antulp | grep mysql
[root@pxcnode66 PXC]# mysql -uroot -p123qqq...A
[root@pxcnode66 PXC]# mysql -uroot -p123qqq...A
mysql> grant all on *.* to sstuser@"localhost" identified by "123qqq...A";
mysql> show slave status\G;
| wsrep_ready |ON
主服务器上输入新数据
[root@mysql11 ~]# mysql -uroot -p123qqq...A
mysql> insert into user()
values("bob");
Pxcnode66上查看能否同步主服务器上的数据
mysql> select * from gamedb.user where name="bob";
在pxcnode77主机作如下配置:
– 安装PXC软件、修改配置文件、启动mysql服务
– 数据库管理员登录、查看状态信息、查看数据
[root@pxcnode10 ~]# cd /03/PXC/
[root@pxcnode10 PXC]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm

在pxcnode88主机做如下配置:
– 安装PXC软件、修改配置文件、启动mysql服务
– 数据库管理员登录、查看状态信息、查看数据
[root@pxcnode88 PXC]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm
