Mysql利用mysql_multi配置一臺主機多個實例

在Mysql官方幫助文檔中，詳細記錄中Mysql的啟動方式，有mysqld_safe、mysql.server、mysql_multi這三種。關于mysql_multi的介紹：

Mysqld_multi可以管理多個幀聽不同Unix套接字文件和TCP/IP端口的連接的mysqld 進程。它可以啟動或停止服務器，或報告它們的當前狀態。

即可以管理多個實例。

筆者在之前也介紹過使用mysqld_safe啟用多實例的方法，啟動和關閉都指定配置文件，實例間是對立的，互不影響。成功的部署了多個實例主從Replication，今天也介紹下mysql_multi多實例管理，配置簡單，方便管理。

1、首先配置my.cnf文件，列出我的Mysql配置文件：

[mysqld_multi]

mysqld = /usr/local/mysql/bin/mysqld_safe #根據自己的mysql目錄配置

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

[mysqld1]

port = 3306

socket = /tmp/mysql3306.sock

basedir=/usr/local/mysql

datadir=/mysqldata/data3306

log-slow-queries=slow_query.txt

long_query_time=2

skip-locking

skip-name-resolve

skip-innodb

max_allowed_packet = 256M

query_cache_size=256M

max_connections=2000

max_connect_errors=10000

key_buffer_size=6000M

read_buffer_size=32M

read_rnd_buffer_size = 32M

myisam_sort_buffer_size=512M

tmp_table_size=1024M

old-passwords

interactive_timeout=60

wait_timeout=60

connect_timeout=60

table_cache=8192

thread_cache_size=512

sort_buffer_size=128M

back_log = 500

thread_concurrency=48

expire_logs_days=10

log-bin=mysql-bin

[mysqld2]

port = 3307

socket = /tmp/mysql3307.sock

basedir=/usr/local/mysql

datadir=/mysqldata/data3307

log-slow-queries=slow_query.txt

long_query_time=2

skip-locking

skip-name-resolve

skip-innodb

max_allowed_packet = 256M

query_cache_size=256M

max_connections=2000

max_connect_errors=10000

key_buffer_size=6000M

read_buffer_size=32M

read_rnd_buffer_size = 32M

myisam_sort_buffer_size=512M

tmp_table_size=1024M

old-passwords

interactive_timeout=60

wait_timeout=60

connect_timeout=60

table_cache=8192

thread_cache_size=512

sort_buffer_size=128M

back_log = 500

thread_concurrency=48

expire_logs_days=10

log-bin=mysql-bin

[mysqldump]

quick

max_allowed_packet = 512M

[mysql]

no-auto-rehash

[isamchk]

key_buffer = 512M

sort_buffer_size = 32M

read_buffer = 2M

write_buffer = 2M

[myisamchk]

key_buffer = 512M

sort_buffer_size = 32M

read_buffer = 2M

write_buffer = 2M

[mysqlhotcopy]

interactive-timeout

2、初始化數據庫目錄：

shell>cd /usr/local/mysql/;./scripts/mysql_install_db --datadir=/mysqldata/data3307/ --user=mysql

shell>cd /usr/local/mysql/;./scripts/mysql_install_db --datadir=/mysqldata/data3306/ --user=mysql

初始話成功，會提示OK，否則查看數據庫目錄是否有權限。

3、啟動多實例：

shell>/usr/local/mysql/bin/mysqld_multi start 1-2

或

shell>/usr/local/mysql/bin/mysqld_multi start 1

shell>/usr/local/mysql/bin/mysqld_multi start 2

注意這里的1、2對應my.cnf配置文件 mysqld1、mysqld2，以此來區分。

4、本機登錄Mysql，如3307端口：

shell>mysql -S /tmp/mysql3307.sock

mysql> show variables like 'datadir';

+---------------+----------------------+

| Variable_name | Value |

+---------------+----------------------+

| datadir | /mysqldata/data3307/ |

+---------------+----------------------+

1 row in set (0.00 sec)

4、關閉數據庫實例

shell>/usr/local/mysql/bin/mysqld_multi stop 1-2

或

shell>/usr/local/mysql/bin/mysqld_multi stop 1

shell>/usr/local/mysql/bin/mysqld_multi stop 2
