今天有時間寫寫，不然心坎里總有點不爽。單機多實例一直都是屌絲的處事風格。。。
實驗環境
RHEL6.5
172.24.0.130 3306
172.24.0.130 3307
01、本次采用的MYSQL二進制快速安裝

#截圖操作
#根據需求選擇對應的版本
02、解壓並建立數據目錄
tar zxf xxx.tar.gz -C /tmp
mkdir -p {data_3306,data3307} #存放數據
mkdir conf #放my.cnf
03、修改配置文件my.cnf
#3306my.cnf
[client] default-character-set=utf8 #客戶端連接編碼 [mysql] auto-rehash #客戶端tab補全 default-character-set=utf8 #編碼 [mysqld]
user=mysql #運行賬戶 port=3306 #定義端口 log-bin=mysql-bin #開啟二進制日志 server-id=001 #定義服務ID max_allowed_packet=50M ###最大 wait_timeout=3600 ###等待超時默認s interactive_timeout=3600 ###活動超時 innodb_buffer_pool_size = 128M join_buffer_size = 128M sort_buffer_size = 2M read_rnd_buffer_size = 2M basedir=/tmp/mysql_mulit #MYSQL根目錄 datadir=/tmp/mysql_mulit/data_3306 #MYSQL數據存放目錄 socket=/tmp/3306_mysql.sock #套接字 init_connect='SET collation_connection = utf8_unicode_ci' init_connect='SET NAMES utf8' character-set-server=utf8 #定義數據庫默認字符 server\collation collation-server=utf8_unicode_ci skip-character-set-client-handshake symbolic-links=0 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
lower_case_table_names = 0 #對表的大小寫不敏感
[mysqld_safe] log-error=/tmp/3306_err.log #錯誤日志 pid-file=/tmp/mysql_mulit/data_3306/mysqld.pid #pid,多協議通信 tcp/sock
3307my.cnf
[client] default-character-set=utf8 #客戶端連接編碼 [mysql] auto-rehash #客戶端tab補全 default-character-set=utf8 #編碼 [mysqld]
user=mysql port=3307 #定義端口 log-bin=mysql-bin #開啟二進制日志 server-id=011 #定義服務ID max_allowed_packet=50M ###最大 wait_timeout=3600 ###等待超時默認s interactive_timeout=3600 ###活動超時 innodb_buffer_pool_size = 128M join_buffer_size = 128M sort_buffer_size = 2M read_rnd_buffer_size = 2M basedir=/tmp/mysql_mulit #MYSQL根目錄 datadir=/tmp/mysql_mulit/data_3307 #MYSQL數據存放目錄 socket=/tmp/3307_mysql.sock #套接字 init_connect='SET collation_connection = utf8_unicode_ci' init_connect='SET NAMES utf8' character-set-server=utf8 #定義數據庫默認字符 server\collation collation-server=utf8_unicode_ci skip-character-set-client-handshake symbolic-links=0 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES lower_case_table_names = 0 #對表的大小寫不敏感 [mysqld_safe] log-error=/tmp/3307_err.log #錯誤日志 pid-file=/tmp/mysql_mulit/data_3307/mysqld.pid #pid,多協議通信 tcp/sock
04、初始化數據庫
./scripts/mysql_install_db --defaults-file=conf/3306my.cnf
./scripts/mysql_install_db --defaults-file=conf/3306my.cnf
05、啟動數據庫
./bin/mysqld_safe --defaults-file=conf/3306my.cnf &
./bin/mysqld_safe --defaults-file=conf/3307my.cnf &
06、初始化root密碼
./bin/mysqladmin -P 3306 -u root password '123123'
./bin/mysqladmin -P 3307 -u root password '123123'
07、master主機設置（3306）
建立從復制賬號
grant replication slave on *.* to 'mysync'@'%' identified by '123456'; #所有IP
grant replication slave on *.* to 'mysync'@'localhost' identified by '123456'; #127.0.0.1
grant replication slave on *.* to 'mysync'@'zabibx' identified by '123456'; #172.24.0.130, zabbix是主機名
查看Master信息
mysql> show master status; #目的跟slave對上口徑
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000003 | 541 | | | |
+------------------+----------+--------------+------------------+-------------------+
08、Slave從主機設置（3307）
進入mysql與master主機建立連接
change master to master_host='172.24.0.130',master_port=3306,master_user='mysync',master_password='123456', master_log_file='mysql-bin.000003',master_log_pos=541;
show slave status\G；
start slave; #啟動從主機 stop slave；停止從主機
#截圖中兩個yes說明從機已經連接到主機
