MySQL主從配置筆記

由於要寫一個訂閱MySQL binlog的基礎服務，因此須要配置一套MySQL主從，作開發環境，在這裏作個筆記。

MySQL版本5.7.17

主庫配置

[mysqld]
log_bin = /path/mysql/master/data/log_bin

basedir = /usr/local/Cellar/mysql/5.7.17
datadir = /path/mysql/master/data
port = 3306
server_id = 13306
socket = mysql.sock

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

從庫配置

[mysqld]
log_bin = /path/mysql/slave/data/log_bin
relay_log = /path/mysql/slave/data/relay_log
relay-log-index = /path/mysql/slave/data/relay-log-index
relay-log-info-file = /path/mysql/slave/data/relay-relay-log.info
replicate-do-db = test
log_slave_updates = 1

basedir = /usr/local/Cellar/mysql/5.7.17
datadir = /path/mysql/slave/data
port = 3307
server_id = 13307
socket = mysql.sock
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

初始化主MySQL，user是root，密碼爲空，slave初始化改下datadir參數

mysqld --initialize-insecure --user=root --datadir=/path/mysql/master/data

啓動主MySQL，啓動slave請改下defaults-file參數

mysqld --defaults-file=/path/mysql/master/etc/my.cnf

在主庫建立一個同步帳戶

GRANT REPLICATION SLAVE ON *.* TO repl@'%' IDENTIFIED BY 'pwd';
FLUSH PRIVILEGES;

在從庫開啓同步

CHANGE MASTER TO MASTER_HOST='127.0.0.1',MASTER_PORT= 3306, MASTER_LOG_FILE='log_bin.000001', MASTER_LOG_POS=1, MASTER_BIND='', MASTER_USER='repl',MASTER_PASSWORD='pwd';
START SLAVE;

關閉主MySQL，關閉slave，請修改相應的地址和端口

mysqladmin -uroot -p -h 127.0.0.1 -P 3306 shutdown

完成。
