MySQL 5.6版本二進制包多實例（版本2）

MySQL安裝

下載：http://ftp.ntu.edu.tw/MySQL/Downloads/MySQL-5.6/

（1）解壓
tar -zxvf mysql-5.6.46-linux-glibc2.12-x86_64.tar.gz -C /usr/local/

（2）創建軟鏈接
ln -sv /usr/local/mysql-5.6.46-linux-glibc2.12-x86_64 /usr/local/mysql

（3）創建mysql 用戶
useradd -M -s /sbin/nologin mysql

（4）創建目錄結構和授權
mkdir /opt/data/{3306,3307}/ -p
chown -R mysql.mysql /opt/data

（5）添加環境變量
echo 'export PATH=$PATH:/usr/local/mysql/bin' >>  /etc/profile  
export PATH=$PATH:/usr/local/mysql/bin

（6）創建my.cnf文件 nano /etc/my.cnf

（7）初始化數據庫

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/opt/data/3306/data --defaults-file=/etc/my.cnf 
/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/opt/data/3307/data --defaults-file=/etc/my.cnf 

（8）修改單獨啓動配置
#cd /opt/data/3306/data 
#nano my.cnf

 [client]    
port        = 3306     
socket      = /opt/data/3306/data/mysql3306.sock

[mysqld]    
port        = 3306     
socket      =  /opt/data/3306/data/mysql3306.sock     
datadir     =  /opt/data/3306/data
max_connections=1000
character-set-server=utf8
innodb_file_per_table=1
lower_case_table_names=1 
log_error=/opt/data/3306/data/mysql3306.err 

#cd /opt/data/3307/data 
#nano my.cnf

 [client]    
port        = 3307     
socket      = /opt/data/3307/data/mysql3307.sock

[mysqld]    
port        = 3307     
socket      =  /opt/data/3307/data/mysql3307.sock     
datadir     =  /opt/data/3307/data
max_connections=1000
character-set-server=utf8
innodb_file_per_table=1
lower_case_table_names=1 
log_error=/opt/data/3307/data/mysql3307.err 

（9）啓動多實例

/usr/local/mysql/bin/mysqld_safe --defaults-file=/opt/data/3306/data/my.cnf &
/usr/local/mysql/bin/mysqld_safe --defaults-file=/opt/data/3307/data/my.cnf &

（10）修改密碼
/usr/local/mysql/bin/mysqladmin -u root password "123456" -S /opt/data/3306/data/mysql3306.sock 
/usr/local/mysql/bin/mysqladmin -u root password "123456" -S /opt/data/3307/data/mysql3307.sock

查看進程
netstat -tulnp

（11）登陸數據庫
/usr/local/mysql/bin/mysql -uroot -p -S /opt/data/3306/data/mysql3306.sock 
/usr/local/mysql/bin/mysql -uroot -p -S /opt/data/3307/data/mysql3307.sock 

GRANT SHUTDOWN ON *.* TO 'multi_admin'@'localhost' IDENTIFIED BY 'multi_admin'; FLUSH PRIVILEGES;  # 該賬號用於 mysqld_multi 實例管理
GRANT ALL PRIVILEGES ON *.* TO 'dba_user'@'%' IDENTIFIED BY PASSWORD '*3F4D6E9B7A42AD6D870BBDB137B8C00B097A4AB8' WITH GRANT OPTION; FLUSH PRIVILEGES;

ps -ef | grep mysql 
殺掉mysql 進程

（12）使用mysqld_multi進行多實例管理
啓動全部實例：/usr/local/mysql/bin/mysqld_multi start  
查看全部實例狀態：/usr/local/mysql/bin/mysqld_multi report  
啓動單個實例：/usr/local/mysql/bin/mysqld_multi start 3306  
停止單個實例：/usr/local/mysql/bin/mysqld_multi stop 3306  
查看單個實例狀態：/usr/local/mysql/bin/mysqld_multi report 3306

注：mysqld_multi stop無效問題 
GRANT SHUTDOWN ON *.* TO 'multi_admin'@'localhost' IDENTIFIED BY 'multi_admin'; FLUSH PRIVILEGES;
