mysql-5.1.73多实例安装启动
1. 源码包下载:http://download.softagency.net/MySQL/Downloads/MySQL-5.1/
2. 编译安装
groupadd mysql useradd -r -g mysql mysql mkdir /data/mysql_multi/mysql_exa1/ cd /data/mysql_multi/mysql_exa1/ mkdir data binlog log mkdir /data/mysql_multi/mysql_exa2/ cd /data/mysql_multi/mysql_exa2/ mkdir data binlog log chown -R mysql:mysql /data/mysql_multi/mysql_exa2/ /data/mysql_multi/mysql_exa1/ cd /data/installs/mysql-5.1.73 ./configure --prefix=/usr/local/mysql5.1 make make install cd /usr/local/mysql5.1/bin/ ./mysql_install_db --user=mysql --basedir=/usr/local/mysql5.1 --datadir=/data/mysql_multi/mysql_exa1/data/ ./mysql_install_db --user=mysql --basedir=/usr/local/mysql5.1 --datadir=/data/mysql_multi/mysql_exa2/data/ cp -rp ../share/mysql/mysqld_multi.server /etc/init.d/mysql_multi #复制启动文件 vim /etc/init.d/mysql_multi #修改basedir 和 datadir
3. 配置多实例
[mysqld_multi] mysqld = /usr/local/mysql5.1/bin/mysqld_safe mysqladmin = /usr/local/mysql5.1/bin/mysqladmin user = root #管理实例时指定的用户名和密码 password = 1234 [client] #port = 3306 #socket = /data/mysql_multi/mysql_exa1/mysql.sock [mysqld3307] server-id = 3307 port = 3307 socket = /data/mysql_multi/mysql_exa1/mysql.sock pid-file = /data/mysql_multi/mysql_exa1/mysql.pid datadir = /data/mysql_multi/mysql_exa1/data log-error = /data/mysql_multi/mysql_exa1/log/error.log long_query_time = 1 slow_query_log_file = /data/mysql_multi/mysql_exa1/log/slow-query.log log-bin = /data/mysql_multi/mysql_exa1/binlog/mysql-bin log-bin-index = /data/mysql_multi/mysql_exa1/binlog/mysql-bin.index expire_logs_days = 2 binlog_format=mixed skip-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M [mysqld3308] server-id = 3308 port = 3308 socket = /data/mysql_multi/mysql_exa2/mysql.sock pid-file = /data/mysql_multi/mysql_exa2/mysql.pid datadir = /data/mysql_multi/mysql_exa2/data log-error = /data/mysql_multi/mysql_exa2/log/error.log long_query_time = 1 slow_query_log_file = /data/mysql_multi/mysql_exa2/log/slow-query.log log-bin = /data/mysql_multi/mysql_exa2/binlog/mysql-bin log-bin-index = /data/mysql_multi/mysql_exa2/binlog/mysql-bin.index expire_logs_days = 2 binlog_format=mixed skip-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
4. 启动多实例
root@192.168.100.246:/usr/local/mysql5.1/bin# /etc/init.d/mysqld_multi start 3307 root@192.168.100.246:/usr/local/mysql5.1/bin# /etc/init.d/mysqld_multi start 3308 root@192.168.100.246:/usr/local/mysql5.1/bin# netstat -lntp | grep mysql tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 26218/mysqld tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 31910/mysqld tcp 0 0 0.0.0.0:3308 0.0.0.0:* LISTEN 32154/mysqld
5. 关闭多实例
5.1 分别设置密码
root@192.168.100.246:/usr/local/mysql5.1/bin# mysql -uroot -p -S /data/mysql_multi/mysql_exa1/mysql.sock #指定sock文件路径登录 Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

5.2 关闭实例
root@192.168.100.246:/usr/local/mysql5.1/bin# /etc/init.d/mysqld_multi stop 3307 root@192.168.100.246:/usr/local/mysql5.1/bin# /etc/init.d/mysqld_multi stop 3308 root@192.168.100.246:/usr/local/mysql5.1/bin# netstat -lntp | grep mysql tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 26218/mysqld
6. 注意事项
6.1 mysql_multi.log默认路径:/usr/local/mysql5.1/share/mysqld_multi.log
6.2 新加实例时,只需要在配置文件加上实例相关配置,启动实例即可,停止实例也类似
