运行环境：CentOS 7.4+MariaDB 10.3.8
由于硬件资源有限不想使用虚拟机，便决定尝试在一台物理机上运行三个mysql实例搭建cluster集群。
0.单主机多实例运行MySQL的相关规划：
节点信息 配置文件 数据目录 mysql端口号 SST端口 WSREP_CLUSTER端口
node1 node1.cnf /data/mysql/node1 4010 4020 4030
node2 node2.cnf /data/mysql/node2 5010 5020 5030
node3 node3.cnf /data/mysql/node3 6010 6020 60301.下载mariadb 10.3.8的二进制文件解压：
#wget https://mirrors.shu.edu.cn/mariadb//mariadb-10.3.8/bintar-linux-systemd-x86_64/mariadb-10.3.8-linux-systemd-x86_64.tar.gz
#tar -xzvf mariadb-10.3.8-linux-systemd-x86_64.tar.gz -C /usr/local
#mv /usr/local/mariadb-10.3.8-linux-systemd-x86_64 /usr/local/mysql注释：由于mariadb 10.3.8二进制包启动报错信息如下：
报错信息：

--解决办法：
快速解决方法：使用rpm快速安装：
#wget http://yum.mariadb.org/10.3/rhel74-amd64/rpms/galera-25.3.23-1.rhel7.el7.centos.x86_64.rpm
#rpm -ivh galera-25.3.23-1.rhel7.el7.centos.x86_64.rpm
使用打包好的galera包替换二进制包。2.设置环境变量：
# cat /etc/profile.d/mysql.sh
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:/usr/local/mysql/bin编辑文件使用source命令立即生效：source /etc/profile.d/mysql.sh

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/node1 --defaults-file=/data/mysql/node1.cnf
第一个节点第一次启动：
/usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql/node1.cnf --wsrep-new-cluster &
第一个实例第一次启动后再次启动的命令：
/usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql/node1.cnf & 5.启动之后登陆第一个实例后设置用户名和密码(仅在第一个实例)：
alter user root@'localhost' identified by 'oracle';
grant all privileges on *.* to root@'%' identified by 'oracle' with grant option;
GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON *.* TO backup@'%' identified by 'backup';
GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON *.* TO backup@'localhost' identified by 'backup';
flush privileges;

| wsrep_cert_index_size | 1 |

2 rows in set (0.001 sec)7.进行数据验证：
登陆第一个实例创建表并插入数据，到第二个和第三个实例中验证和插入数据测试：
# mysql -p -S /tmp/mysql_node1.sock
MariaDB [(none)]> create database wuhan;
Query OK, 1 row affected (0.552 sec)
MariaDB [(none)]> create table wuhan.city(cityid int unsigned not null auto_increment primary key, cityname varchar(20));
Query OK, 0 rows affected (0.191 sec)
MariaDB [(none)]> insert into wuhan.city(cityname)values('beijing');
Query OK, 1 row affected (0.350 sec)
MariaDB [(none)]> insert into wuhan.city(cityname)values('shanghai');
Query OK, 1 row affected (0.014 sec)
--登陆第二个节点：
# mysql -p -S /tmp/mysql_node2.sock

8.数据库实例的关闭：
#kill -9 `ps -ef | grep -i mysql | awk ' { print $2}'`
或者登陆实例使用shutdown命令：
#mysql -p -S /tmp/mysql_node2.sock
>shutdown;9.实例运行端口查看：
# netstat -nultp | grep -i mysql
