mysql5.7-Group Replication
什么是Group Replication
基于组的复制（Group-based Replication）是一种被使用在容错系统中的技术。Replication-group（复制组）是由能够相互通信的多个服务器（节点）组成的。

groupadd mysql
useradd -M -s/sbin/nologin -g mysql -r mysql
下载boots（mysql01-03）
mysql 5.7 依赖于boost_1_59_0或更高版本, 查看系统是否自带boost, 如果有就卸载了
下载boost_1_59_0.tar.gz
放在/usr/local/boost里面
安装mysql（mysql01-03）
mkdir -p /data/mysql/data
tar zxvf mysql-5.7.21.tar.gz
cd mysql-5.7.21
cmake . -DCMAKE_INSTALL_PREFIX=/data/mysql -DMYSQL_DATADIR=/data/mysql/data -DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock -DSYSCONFDIR=/etc -DMYSQL_USER=mysql -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DENABLED_LOCAL_INFILE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/usr/local/boost/ -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_EMBEDDED_SERVER=1

FLUSH PRIVILEGES;
##关闭
SET SQL_LOG_BIN=1;
###执行同步语句
CHANGE MASTER TO MASTER_USER='rpl_user', MASTER_PASSWORD='rpl_pass' FOR CHANNEL 'group_replication_recovery';
