mysqld_multi部署mysql单机多实例

1.安装gcc-c++、ncurses依赖包

?

1	# yum install gcc-c++  ncurses-devel

2.安装cmake，用来编译mysql

?

1 2 3 4 5 6 7 8

# tar -xvf cmake-3.2.0-.tar.gz # mv cmake-3.2.0 cmake # mv cmake /tmp/ # cd /tmp/cmake/ # ./bootstrap # make # make install # cmake --version

3.安装bison

?

1 2 3 4 5 6 7 8

# tar -xvf bison-3.0.tar.gz # mv bison-3.0 bison # mv bison /tmp # cd /tmp/bison/ # ./cofigure # make # make install # bison --version

4.创建mysql用户

?

1 2	# /usr/sbin/groupadd mysql # useradd -s /sbin/nologin -g  mysql -M mysql

5.编译安装

配置

?

1 2 3 4 5 6 7 8 9 10 11

# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DEXTRA_CHARSETS=all \ -DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DMYSQL_TCP_PORT=3306 \ -DMYSQL_USER=mysql \

生成可执行文件

?

1

# make

安装

?

1	# make install

6.创建多实例的数据文件目录

?

1	# mkdir -p /data/{3306,3307}/data/

7.初始化数据库,创建基础的数据库文件

?

1 2 3

# cd /usr/local/mysql/scripts/ #./mysql_install_db  --user=mysql --basedir=/usr/local/mysql --datadir=/data/3306/data/ #./mysql_install_db  --user=mysql --basedir=/usr/local/mysql --datadir=/data/3307/data/

8.配置多实例的文件权限
授权mysql用户和组管理多实例目录/data

?

1	# chown -R mysql.mysql /data

9.配置多实例的配置文件

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

# vim /etc/my.cnf [mysqld_multi]   mysqld     = /usr/local/mysql/bin/mysqld_safe   mysqladmin = /usr/local/mysql/bin/mysqladmin   user       = multi_admin   password   = multipass       [mysqld3306]   socket          = /data/3306/data/mysql.sock port            = 3306 log-error       = /data/3306/data/mysql.err  datadir         = /data/3306/data/  pid-file        = /data/3306/data/mysql.pid log-bin         = /data/3306/data/mysql-bin relay_log       = /data/3306/data/relay-bin slow_query_log_file     = /data/3306/data/slowquery.log general_log_file        = /data/3306/data/general.log user                    = mysql       [mysqld3307]   socket          = /data/3307/data/mysql.sock port            = 3307 log-error       = /data/3307/data/mysql.err  datadir         = /data/3307/data/  pid-file        = /data/3307/data/mysql.pid log-bin         = /data/3307/data/mysql-bin relay_log       = /data/3307/data/relay-bin slow_query_log_file     = /data/3307/data/slowquery.log general_log_file        = /data/3307/data/general.log user                    = mysql

10.配置mysql命令的环境变量

?

1 2	# echo 'export PATH=/usr/local/mysql/bin:$PATH' >> /etc/profile # source /etc/profile

11.启动
查看状态

?

1 2 3 4

# mysqld_multi --defaults-extra-file=/etc/my.cnf report   Reporting MySQL servers MySQL server from group: mysqld3306 is not running MySQL server from group: mysqld3307 is not running

启动实例

?

1 2 3 4 5

# mysqld_multi  start  # mysqld_multi --defaults-extra-file=/etc/my.cnf report Reporting MySQL servers MySQL server from group: mysqld3306 is running MySQL server from group: mysqld3307 is running

12.修改的root用户的密码并且限制只能本机登陆

?

1 2	# mysqladmin -S /data/3306/data/mysql.sock -u root -h 'localhost' password 'XXXXXXXX' # mysqladmin -S /data/3307/data/mysql.sock -u root -h 'localhost' password 'XXXXXXXX'

13.使用root用户登陆

?

1 2	# mysql -S  /data/3306/data/mysql.sock -u root -p # mysql -S  /data/3307/data/mysql.sock -u root -p

14.创建关闭实例的用户

?

1 2	mysql> CREATE USER 'multi_admin'@'localhost' IDENTIFIED BY 'multipass'; mysql> GRANT SHUTDOWN ON *.* TO 'multi_admin'@'localhost';

14.停止实例
停止所有实例

?

1	# mysqld_multi  stop

停止实例1

?

1	# mysqld_mulit stop 3306

　

管理多实例的话可以使用mysqlmanager实例管理器，管理器来会比较方面
