我的博客已迁移到xdoujiang.com请去那边和我交流
前言:领导要求在1台DELL R710上安装多个mysql实例
一、安装第1个实例
1、当前系统
cat
/etc/debian_version
6.0.10
2、查看安装包
apt-cache search mysql-server|
grep
"mysql-server"
mysql-server-5.1 - MySQL database server binaries and system database setup
mysql-server-core-5.1 - MySQL database server binaries
mysql-server - MySQL database server (metapackage depending on the latest version)
3、安装mysql(会安装mysql相关的一系列的包)
apt-get -y
install
mysql-server --force-
yes
二、安装第二个实例
1、创建目录(我这边将第二个实例安装在
/opt
下)
cd
/opt/
mkdir
mysql3307
2、复制mysql表和配置文件
cd
/var/lib/mysql/
cp
-a mysql
/opt/mysql3307/
cp
/etc/mysql/my
.cnf
/opt/mysql3307/
3、修改配置(一般就是改下port和sock和pid和datadir路径)
port = 3307
socket =
/var/run/mysqld/mysqld3307
.sock
pid-
file
=
/var/run/mysqld/mysqld3307
.pid
datadir =
/opt/mysql3307
4、给mysql权限
chown
-R mysql.root
/opt/mysql3307/
5、启mysql(这里使用mysql用户启)
修改
/etc/passed
文件
mysql:x:102:104:MySQL Server,,,:
/var/lib/mysql
:
/bin/bash
su
- mysql
/usr/sbin/mysqld
--defaults-
file
=
/opt/mysql3307/my
.cnf --basedir=
/usr
--datadir=
/opt/mysql3307/
--user=mysql --pid-
file
=
/var/run/mysqld/mysqld3307
.pid --skip-external-locking --port=3307 --socket=
/var/run/mysqld/mysqld3307
.sock &

Version:
'5.1.73-1'
socket:
'/var/run/mysqld/mysqld3307.sock'
port: 3307 (Debian)
6、最后查看2个mysql实例是否正常运行着
ps
aux|
grep
mysql
root 2152 0.0 0.0 3956 616 ? S 08:53 0:00
/bin/sh
/usr/bin/mysqld_safe
mysql 2276 0.0 3.6 182456 37560 ? Sl 08:53 0:01
/usr/sbin/mysqld
--basedir=
/usr
--datadir=
/var/lib/mysql
--user=mysql --pid-
file
=
/var/run/mysqld/mysqld
.pid --socket=
/var/run/mysqld/mysqld
.sock --port=3306
root 2277 0.0 0.0 5348 688 ? S 08:53 0:00 logger -t mysqld -p daemon.error

Sl 09:30 0:00
/usr/sbin/mysqld
--defaults-
file
=

.cnf --basedir=

--user=mysql --pid-
file
=
/var/run/mysqld/mysqld3307
.pid --skip-external-locking --port=3307 --socket=
/var/run/mysqld/mysqld3307
.sock
mysql 2495 0.0 0.1 16340 1136 pts

R+ 09:30 0:00
ps
aux
mysql 2496 0.0 0.0 7548 820 pts
/0
S+ 09:30 0:00
grep
mysql
7、登陆2个mysql实例看下
mysql -uroot -predhat -S
/var/run/mysqld/mysqld
.sock

Bye
mysql -uroot -predhat -S

mysql@10:~$
三、引擎
当前版本引擎
mysql -uroot -predhat -S
/var/run/mysqld/mysqld
.sock -e
"show engines;"
+------------+---------+----------------------------------------------------------------+--------------+------+------------+
| Engine | Support | Comment | Transactions | XA | Savepoints |
+------------+---------+----------------------------------------------------------------+--------------+------+------------+
| InnoDB | YES | Supports transactions, row-level locking, and foreign keys | YES | YES | YES |
| MRG_MYISAM | YES | Collection of identical MyISAM tables | NO | NO | NO |
| BLACKHOLE | YES |
/dev/null
storage engine (anything you write to it disappears) | NO | NO | NO |
| CSV | YES | CSV storage engine | NO | NO | NO |
| MEMORY | YES | Hash based, stored
in
memory, useful
for
temporary tables | NO | NO | NO |
| FEDERATED | NO | Federated MySQL storage engine | NULL | NULL | NULL |
| ARCHIVE | YES | Archive storage engine | NO | NO | NO |
| MyISAM | DEFAULT | Default engine as of MySQL 3.23 with great performance | NO | NO | NO |
+------------+---------+----------------------------------------------------------------+--------------+------+------------+
配置修改默认引擎为innodb
是在[mysqld]这个里面
default_table_type = innodb
5.5的话默认引擎直接是innodb了 不需要修改
