做測試還是採用二進位制方式安裝，簡單方便快速，在原環境安裝好的基礎上。
mysql-5.6.x二進位制版本安裝記錄
個人不喜歡採用mysqlmulti方式配置多例項，還是採用多例項多程序方式配置。
# mkdir -p /usr/local/mysql/mysql3307
# chown mysql:mysql /usr/local/mysql/mysql3307
初始化例項目錄
# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/mysql3307
(1) 修改現有配置檔名my.cnf修為3306.cnf,並複製乙個配置檔案名為3307.cnf
(2) 3306.cnf配置檔案修改，埠,sock位置,pid位置,datadir位置等。
[client]
port = 3306
socket = /tmp/mysql3306.sock
[mysqld]
port = 3306
socket = /tmp/mysql3306.sock
datadir = /usr/local/mysql/data
(3) 3307.cnf配置檔案修改
[client]
port = 3307
socket = /tmp/mysql3307.sock
[mysqld]
port = 3307
socket = /tmp/mysql3307.sock
datadir = /usr/local/mysql/mysql3307
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/3306.cnf 2>&1 >/dev/null &
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/3307.cnf 2>&1 >/dev/null &
# /usr/local/mysql/bin/mysql -u root -p -p 3306 -s /tmp/mysql3306.sock
# /usr/local/mysql/bin/mysql -u root -p -p 3307 -s /tmp/mysql3307.sock
修改3307例項密碼:
# /usr/local/mysql/bin/mysqladmin -u root password 'admin' -s /tmp/mysql3307.sock #設定管理員密碼
3306登入示例1:
[root@test ~]# mysql -uroot -p -s /tmp/mysql3306.sock
enter password:
welcome to the mysql monitor. commands end with ; or \g.
your mysql connection id is 14
server version: 5.6.24-log source distribution

type 'help;' or '\h' for help. type '\c' to clear the current input statement.

指定埠號也是可以訪問的：
mysql -uroot -p -h127.0.0.1 -p3307
# /usr/local/mysql/bin/mysqladmin -u root -p -p 3306 -s /tmp/mysql3306.sock shutdown
# /usr/local/mysql/bin/mysqladmin -u root -p -p 3307 -s /tmp/mysql3307.sock shutdown
或採用kill方式，或編寫啟動指令碼。
