一、mysql安装目录说明mysql5.6以二进制安装包安装在/data/mysql56下数据目录为/data/mysql56/data下配置文件为/etc/my.cnf下二、多实例目录说明/mysql-instance |-- 3308 |-- data #3308实例数据目录 |-- 3309 |-- data #3309实例数据目录
1 2 > mkdir -p /mysql-instance/3308/data > mkdir -p /mysql-instance/3309/data三、复制配置文件到实例目录下
1 2 > cp /data/mysql56/support-files/my- default .cnf /mysql-instance/3308/my.cnf > cp /data/mysql56/support-files/my- default .cnf /mysql-instance/3309/my.cnf四、修改配置文件
1 2 > vi /mysql-instance/3308/my.cnf > vi /mysql-instance/3309/my.cnf 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 [client] port = 3308 socket = /mysql-instance/3308/mysql.sock [mysql] no-auto-rehash [mysqld] user = mysql port = 3308 socket = /mysql-instance/3308/mysql.sock basedir = /data/mysql56 datadir = /mysql-instance/3308/data pid-file = /mysql-instance/3308/mysql.pid relay-log = /mysql-instance/3308/relay-bin relay-log-info-file = /mysql-instance/3308/relay-log.info server-id = 12 [mysqld_safe] log-error = /mysql-instance/3308/mysql.err pid-file = /mysql-instance/3308/mysql.pid3309的配置同上，只需把3308的地方换成3309五、创建mysql多实例启动文件
1 2 > vi /mysql-instance/3308/mysql > vi /mysql-instance/3309/mysql 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 31 32 33 34 35 36 37 38 39 40 41 42 #!/bin/sh port=3308 mysql_user= "root" #请填写自已数据库密码 mysql_pwd= "123456" cmd_path= "/data/mysql56/bin" mysql_sock= "/mysql-instance/${port}/mysql.sock" mysql_start() { if [ ! -e "$mysql_sock" ];then printf "mysql start ... \n" /bin/sh ${cmd_path}/mysqld_safe --defaults-file=/mysql-instance/${port}/my.cnf 2>&1 > /dev/null & else printf "mysql is running ... \n" exit fi } mysql_stop() { if [ ! -e "$mysql_sock" ];then printf "mysql is stopped ... \n" exit else printf "mysql stop ... \n" ${cmd_path}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /mysql-instance/${port}/mysql.sock shutdown fi } mysql_restart() { printf "mysql restart ... \n" mysql_stop sleep 2 mysql_start } case $1 in start) mysql_start ;; stop) mysql_stop ;; restart) mysql_restart ;; *) printf "usage: /data/${port}/mysql {start|stop|restart}\n" esac六、授权mysql用户目录权限
1 2 3 > chown -R mysql.mysql /mysql-instance > chmod 700 /mysql-instance/3308/mysql > chmod 700 /mysql-instance/3309/mysql七、初始化mysql多实例数据库文件
1 2 3 > cd /daa/mysql56/scripts > ./mysql_install_db --basedir=/data/mysql56 --datadir=/mysql-instance/3308/data --user=mysql > ./mysql_install_db --basedir=/data/mysql56 --datadir=/mysql-instance/3309/data --user=mysql八、启动mysql多实例
1 2 3 > /mysql-instance/3308/mysql start > /mysql-instance/3309/mysql start > netstat -lntup|grep 330九、登陆mysql实例
