单台[DELL R720]服务器部署多个MySQL实例
一、安装mysql准备
1.1 下载mysql软件包
mkdir -p /home/xuekun/mysql
cd /home/xuekun/tools/mysql
wget
1.2安装mysql软件
yum-y install make gcc-c++ cmake bison bison-devel ncurses-devel
tarxvf mysql-5.6.16.tar.gz
cdmysql-5.6.16
cmake\
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql\
-DMYSQL_DATADIR=/data\
-DSYSCONFDIR=/etc\
-DWITH_MYISAM_STORAGE_ENGINE=1\
-DWITH_INNOBASE_STORAGE_ENGINE=1\
-DWITH_MEMORY_STORAGE_ENGINE=1\

make&& make install
1.3创建mysql用户
groupadd mysql
useradd -g mysql -M -s /sbin/nologin mysql
1.4创建mysql数据文件目录
mkdir -p/data/3306/data
mkdir -p/data/3307/data
tree /data/
/data/
|-- 3306
| `-- data
`-- 3307
`-- data
4 directories, 0 files
1.5 授权mysql用户及组访问数据文件目录
chown -Rmysql:mysql /data/3306
chown -Rmysql:mysql /data/3307
1.6 建立3306,3307my.cnf配置文件
vim /data/3306/my.cnf
vim /data/3307/my.cnf
需要添加的my.cnf内容见附录B：或本文档目录下的my.cnf文件
#授权mysql用户及组访问my.cnf
chown -Rmysql:mysql /data/3306/my.cnf
chown -Rmysql:mysql /data/3307/my.cnf
1.7 建立mysql启动脚本
vim /data/3306/mysql
vim /data/3307/mysql
需要添加的mysql 内容见附录C：或本文档目录下的mysql文件
chmod 700/data/3306/mysql
chmod 700/data/3307/mysql
1.8初始化数据库
vim/etc/profile
PATH=/usr/local/mysql/bin:$PATH
exportPATH
#关闭文件，，运行下面的命令，让配置立即生效
source/etc/profile
cd/usr/local/mysql
scripts/mysql_install_db--datadir=/data/3306/data
InstallingMySQL system tables...
OK
Filling helptables...
OK
To start mysqldat boot time you have to copy
support-files/mysql.serverto the right place for your system
PLEASE REMEMBERTO SET A PASSWORD FOR THE MySQL root USER !
To do so, startthe server, then issue the following commands:
/usr/local/mysql/bin/mysqladmin-u root password 'new-password'
/usr/local/mysql/bin/mysqladmin-u root -h A password 'new-password'
Alternativelyyou can run:
/usr/local/mysql/bin/mysql_secure_installation
which will alsogive you the option of removing the test
databases andanonymous user created by default. This is
stronglyrecommended for production servers.
See the manualfor more instructions.
You can startthe MySQL daemon with:
cd/usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &
You can testthe MySQL daemon with mysql-test-run.pl
cd/usr/local/mysql/mysql-test ; perl mysql-test-run.pl
Please reportany problems with the /usr/local/mysql/bin/mysqlbug script!
scripts/mysql_install_db--datadir=/data/3307/data
InstallingMySQL system tables...
OK
Filling helptables...
OK
同上面3306的内容，因此，此处省略。
chown -Rmysql:mysql /data
1.9 启动数据库
启动mysql实例的命令为
/data/3306/mysqlstart
StartingMySQL...
/data/3307/mysqlstart
StartingMySQL...
检查启动情况：
netstat-lnt|grep 330[6-7]
tcp 0 00.0.0.0:3306 0.0.0.0:* LISTEN
tcp 0 00.0.0.0:3307 0.0.0.0:* LISTEN
并加入/etc/rc.local，设置为开机自启动
echo"/data/3306/mysql start" >>/etc/rc.local
echo"/data/3307/mysql start" >>/etc/rc.local
cat/etc/rc.local
#!/bin/sh
#
# This scriptwill be executed *after* all the other init scripts.
# You can putyour own initialization stuff in here if you don't
# want to dothe full Sys V style init stuff.
touch/var/lock/subsys/local
/data/3306/mysqlstart
/data/3307/mysql start
提示：如果此步中的数据库启动不了，请稍微等待下，如果还不行请查看错误日志，路径在my.cnf的最下面。
