1 环境准备

1.1 关闭firewall

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# systemctl disable firewalld

1.1.2 关闭selinux

yum list|grep mariadb

1.4 安装pxc yum源

wget https://www.percona.com/redir/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm

rpm -ivh percona-release-0.1-6.noarch.rpm

yum clean all

yum makecache

1.5 安装pxc软件

yum install -y Percona-Server-server-57

或者把包下载后直接安装

yum install -y Percona-XtraDB-Cluster-shared-57-5.7.22-29.26.1.el7.x86_64.rpm

yum install -y Percona-XtraDB-Cluster-client-57-5.7.22-29.26.1.el7.x86_64.rpm

yum install -y Percona-XtraDB-Cluster-server-57-5.7.22-29.26.1.el7.x86_64.rpm

1.6 源码安装需要的rpm包

yum install -y git scons gcc gcc-c++ openssl check cmake bison \

boost-devel asio-devel libaio-devel ncurses-devel readline-devel pam-devel \

socat

2 三台机器搭建PXC

192.168.10.159

192.168.10.160

192.168.10.161

2.1 第一节点

2.1.1参数

/etc/my.cnf

wsrep_provider=/usr/lib64/galera3/libgalera_smm.so wsrep_cluster_name=pxc wsrep_cluster_address='gcomm://192.168.10.159,192.168.10.160,192.168.10.161' wsrep_node_name=pxc1 wsrep_node_address=192.168.10.159 wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:passw0rd pxc_strict_mode=ENFORCING binlog_format=ROW default_storage_engine=InnoDB innodb_autoinc_lock_mode=2

2.1.2第一个节点启动

systemctl start [email protected]

2.1.3创建用户

在error log中找到root@localhost的temporary password

grep temp mysql_error.log

CREATE USER 'sstuser'@'localhost' IDENTIFIED BY 'passw0rd'; GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON *.* TO'sstuser'@'localhost'; FLUSH PRIVILEGES;

2.2 第二节点

server_id需要修改

wsrep_provider=/usr/lib64/galera3/libgalera_smm.so wsrep_cluster_name=pxc wsrep_cluster_address='gcomm://192.168.10.159,192.168.10.160,192.168.10.161' wsrep_node_name=pxc2 wsrep_node_address=192.168.10.160 wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:passw0rd pxc_strict_mode=ENFORCING binlog_format=ROW default_storage_engine=InnoDB innodb_autoinc_lock_mode=2

启动：systemctl start mysql

2.3 第三节点

server_id需要修改

wsrep_provider=/usr/lib64/galera3/libgalera_smm.so wsrep_cluster_name=pxc wsrep_cluster_address='gcomm://192.168.10.159,192.168.10.160,192.168.10.161' wsrep_node_name=pxc3 wsrep_node_address=192.168.10.161 wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:passw0rd pxc_strict_mode=ENFORCING binlog_format=ROW default_storage_engine=InnoDB innodb_autoinc_lock_mode=2

启动：systemctl start mysql
