mysql5.6版本多配置文件安装实例

mysql5.6版本多配置文件安装实例

为新实例创建数据目录并赋权

#创建两个目录分别作为两个实例的数据目录
mkdir -p /data/application/mysql-multi-instance/{mysql3307, mysql3308}
#为两个实例的数据目录赋权，避免在初始化数据库时出错
chown mysql:mysql -R /data/application/mysql-multi-instance/{mysql3307, mysql3308}

使用mysql的mysql_install_db实例化数据库

./mysql_install_db --basedir=/data/application/mysql --datadir=/data/application/mysql-multi-instance/mysql3307 --user=mysql

./mysql_install_db --basedir=/data/application/mysql --datadir=/data/application/mysql-multi-instance/mysql3308 --user=mysql

编辑两个实例的配置文件

#这是3307实例的配置文件
[client]  
port            = 3307  
socket          = /tmp/mysql3307.sock  

[mysql]  
no-auto-rehash  


[mysqld]  
user    = mysql  
port    = 3307
socket  = /tmp/mysql3307.sock
basedir = /data/application/mysql
datadir = /data/application/mysql-multi-instance/mysql3307

[mysqldump]  
quick  
max_allowed_packet = 2M  


[mysqld_safe]  
log-error=/data/application/mysql-multi-instance/mysql3307/mysql_3307.err  
pid-file=/data/application/mysql-multi-instance/mysql3307/mysqld.pid

#这是3308实例的配置文件
[client]  
port            = 3308 
socket          = /tmp/mysql3308.sock  

[mysql]  
no-auto-rehash  


[mysqld]  
user    = mysql  
port    = 3308
socket  = /tmp/mysql3308.sock
basedir = /data/application/mysql
datadir = /data/application/mysql-multi-instance/mysql3308

[mysqldump]  
quick  
max_allowed_packet = 2M  


[mysqld_safe]  
log-error=/data/application/mysql-multi-instance/mysql3308/mysql_3308.err  
pid-file=/data/application/mysql-multi-instance/mysql3308/mysqld.pid

启动实例

mysqld_safe --defaults-file=/data/application/etc/mysql3307.cnf --basedir=/data/application/mysql --datadir=/data/application/mysql-multi-instance/mysql3307 --user=mysql &

mysqld_safe --defaults-file=/data/application/etc/mysql3308.cnf --basedir=/data/application/mysql --datadir=/data/application/mysql-multi-instance/mysql3308 --user=mysql &

查看启动结果

#这里开启了默认的3306实例，所以有三个实例
