一个Mysql(5.5版本)设置多个端口运行多个实例。搞了一天,终于弄好,先备忘一下!
一、设置mysqld_multi
复制一份my.cnf,重命名为my_multi.cnf
修改my_multi.cnf,主要配置项目如下
[mysqld_multi] mysqld = /usr/bin/mysqld_safe mysqladmin = /usr/bin/mysqladmin user = root password = 123 #默认的3306端口 [mysqld6] user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp #加一个3308的端口 [mysqld8] user = mysql pid-file = /var/run/mysqld/mysqld8.pid socket = /var/run/mysqld/mysqld8.sock port = 3308 basedir = /usr datadir = /var/lib/mysql8 tmpdir = /tmp
二、创建3308端口的数据存储目录
mkdir /var/lib/mysql8 chown mysql:mysql /var/lib/mysql8
三、修改文件/etc/apparmor.d/usr.sbin.mysqld
修改完成后重启:/etc/init.d/apparmor restart
/usr/sbin/mysqld { #include <abstractions/base> #include <abstractions/nameservice> #include <abstractions/user-tmp> #include <abstractions/mysql> #include <abstractions/winbind> capability dac_override, capability sys_resource, capability setgid, capability setuid, network tcp, /etc/hosts.allow r, /etc/hosts.deny r, /etc/mysql/*.pem r, /etc/mysql/conf.d/ r, /etc/mysql/conf.d/* r, /etc/mysql/*.cnf r, /usr/lib/mysql/plugin/ r, /usr/lib/mysql/plugin/*.so* mr, /usr/sbin/mysqld mr, /usr/share/mysql/** r, /var/log/mysql.log rw, /var/log/mysql.err rw, /var/lib/mysql/ r, /var/lib/mysql/** rwk, /var/log/mysql/ r, /var/log/mysql/* rw, /var/run/mysqld/mysqld.pid rw, /var/run/mysqld/mysqld.sock w, /run/mysqld/mysqld.pid rw, /run/mysqld/mysqld.sock w, #####主要是添加这些读写权限信息,不然后期会报一些莫名的错误 /var/lib/mysql8/ r, /var/lib/mysql8/** rwk, /var/run/mysqld/mysqld8.pid rw, /var/run/mysqld/mysqld8.sock w, /run/mysqld/mysqld8.pid rw, /run/mysqld/mysqld8.sock w, /sys/devices/system/cpu/ r, # Site-specific additions and overrides. See local/README for details. #include <local/usr.sbin.mysqld> }
四、初始化数据库
mysql_install_db --user=mysql --datadir=/var/lib/mysql8 &
五、重新数据库(默认打开3306商品的数据库)
service mysql restart
六、打开新设置端口的数据库
mysqld_multi --defaults-file=/etc/mysql/my_multi.cnf start 8
七、完事,可以查看下了
netstat -ntlp
终于看到可喜的结果如下!
tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 1402/mysqld tcp 0 0 127.0.0.1:3308 0.0.0.0:* LISTEN 2202/mysqld
