? 在測試mysql主從服務器的時候，在一個虛擬機開啟多端口同步不同主庫。

詳細步驟：

? 1.首先下載個mysql5.6的64位二進制源碼包：http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.27-linux-glibc2.5-x86_64.tar.gz

? 2.tar zxvf?mysql-5.6.27-linux-glibc2.5-x86_64.tar.gz解壓

? 3.mv?mysql-5.6.27 /usr/local/mysql

? 4.cp /etc/my.cnf /etc/my3301.cnf

? ?cp /etc/my.cnf /etc/my3302.cnf復制my.cnf的配置文件，開幾個端口就復制幾份，這里開啟3301和3302端口。

? 5.修改/etc/my3301.cnf和my3302.cnf文件

? 如：

1 2 3 4 5 6 7 8 9 10

[client] port?=?3301 socket?=?/tmp/mysql3301.sock default-character-set=UTF [mysqld] port?=?3301 socket?=?/tmp/mysql3301.sock basedir=/usr/local/mysql datadir=/data/mysql1 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

需要修改datadir，port和socket

? 6.創建數據庫指定存放數據的目錄

1 2	mkdir?/data/mysql1 mkdir?/data/mysql2

? 7.初始化數據庫

1 2	/usr/local/mysql/scripts/mysql_install_db?--datadir=/data/mysql1?--user=mysql?--basedir=/usr/local/mysql /usr/local/mysql/scripts/mysql_install_db?--datadir=/data/mysql2?--user=mysql?--basedir=/usr/local/mysql

? 8.啟動mysql

1 2	?/usr/local/mysql/bin/mysqld_safe?--defaults-extra-file=/etc/my3301.cnf?--datadir=/data/mysql1?--user=mysql?& ?/usr/local/mysql/bin/mysqld_safe?--defaults-extra-file=/etc/my3302.cnf?--datadir=/data/mysql2?--user=mysql?&

? 9.netstat -lnp 查看mysql是否啟動

?10.停止mysql，對應sock文件

1	/usr/local/mysql/bin/mysqladmin?-uroot?-S?/tmp/mysql3301.sock?shutdown

?11.使用mysql

1	?mysql?-S?/tmp/mysql3302.sock?-P?3302

另外可以用mysqld_multi管理

vim /etc/my.cnf

[mysqld1]

basedir = /usr/local/mysql

user = mysql

datadir = /data/mysql1

port = 3301

# server_id = .....

socket = /tmp/mysql1.sock

pid-file = /data/mysql1/mysql1.pid

[mysqld2]

user = mysql

datadir = /data/mysql2

basedir = /usr/local/mysql

port = 3302

# server_id = .....

socket = /tmp/mysql2.sock

pid-file = /data/mysql2/mysql2.pid

[mysqld_multi]

mysqld = /usr/local/mysql/bin/mysqld_safe

mysqladmin = /usr/local/mysql/bin/mysqladmin

就可以用/usr/local/mysql/bin/mysqld_multi start/stop/reload/report 0或1

需要注意的是要將/usr/local/mysql/bin加入到PATH里
