服务器：192.168.11.131 master
192.168.11.132 slave
服务器系统
# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
1、下面安装过程两个节点操作相同
# rpm -qa | grep mariadb
postfix-2.10.1-6.el7.x86_64
# rpm -qa | grep mariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64
# rpm -ev postfix-2.10.1-6.el7.x86_64
# rpm -ev mariadb-libs-5.5.44-2.el7.centos.x86_64
# rpm -ivh mysql-community-common-5.7.18-1.el7.x86_64.rpm
# rpm -ivh mysql-community-libs-5.7.18-1.el7.x86_64.rpm
# rpm -ivh mysql-community-client-5.7.18-1.el7.x86_64.rpm
# rpm -ivh mysql-community-server-5.7.18-1.el7.x86_64.rpm
设置开机启动
# systemctl enable mysqld.service
2、两节点配置
创建目录
# mkdir /data/mysql_data
# chown -R mysql:mysql /data/mysql_data
编辑配置文件
# vi /etc/my.cnf
datadir=/data/mysql_data
character_set_server=utf8
sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
# innodb optimization
innodb_buffer_pool_size=8G
innodb_log_file_size=256M
innodb_flush_method=O_DIRECT
max_connections=500
innodb_autoextend_increment=128
启动服务
# service mysqld start
主节点密码
# cat /var/log/mysqld.log
A temporary password is generated for root@localhost: l+7jtY6QEfut
从节点密码
# cat /var/log/mysqld.log
A temporary password is generated for root@localhost: sLxt;f?671RO
mysql> set password=password('Password123!');
密码随意设置（符合规则就行）
关闭服务
# service mysqld stop
3、主节点配置
# vi /etc/my.cnf
server-id=1
log-bin=mysql-bin
binlog_format=mixed
innodb_flush_log_at_trx_commit=1
sync_binlog=1
expire_logs_days=15
relay_log=mysql-realy-bin
4、从节点配置
# vi /etc/my.cnf
server-id=2
log_bin=mysql-bin
relay_log=mysql-relay-bin
log-slave-updates=on
expire_logs_days=15
replicate-ignore-db=sys
replicate-ignore-db=mysql
replicate-ignore-db=information_schema
replicate-ignore-db=performance_schema
启动服务
# service mysqld start
5、主节点配置同步
mysql> create user repluser@'%' identified by 'Password123!';
Query OK, 0 rows affected (0.00 sec)
mysql> grant replication slave, replication client on *.* to repluser@'%';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 | 2165 | | | |
+------------------+----------+--------------+------------------+-------------------+
6、从节点配置同步
mysql> CHANGE MASTER TO MASTER_HOST='192.168.11.131', MASTER_USER='repluser', MASTER_PASSWORD='Password123!', MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=2165;
Query OK, 0 rows affected, 2 warnings (0.00 sec)
mysql> start slave;
Query OK, 0 rows affected (0.00 sec)
mysql> show slave status\G

mysql> drop user missingcust@'%';
7、两节点验证
主节点配置验证：
mysql> create database ceshi_db;
Query OK, 1 row affected (0.00 sec)
mysql> use ceshi_db;
Database changed
mysql> create table home(id int(10) not null,name char(10));
Query OK, 0 rows affected (0.02 sec)
从节点验证;
mysql> show databases;

| performance_schema |

+--------------------+
5 rows in set (0.00 sec)
mysql> use ceshi_db;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
