CentOS安装MySQL多实例服务器--multi

 

操作系统：CentOS 5.6 x86_64

 

硬件环境：

 

CPU:Intel(R) Xeon(R) CPU E5620  @ 2.40GHz

 

内存：32G

 

硬盘：300G*2 10K

 

软件环境：

 

gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)

 

mysql 5.1.59.tar.gz

 

libunwind-1.0.tar.gz

 

google-perftools-1.8.3.tar.gz

 

上述软件假设存放在目录/root/soft下

 

 

 

实验目的：在CentOS下安装MySQL并实现多实例数据库服务器及innodb-plugin应用

 

 

 

步骤：

 

#创建日志和运行目录

 

mkdir -p /opt/logs /opt/run

 

chmod 777 /opt/run

 

#添加组和用户

 

groupadd mysql

 

useradd -g mysql -s /sbin/nologin mysql

#安装libunwind

 

1. tar zxf libunwind-1.0.tar.gz
    
2. cd libunwind-1.0
    
3. autoreconf -fi
