一、实验环境

系统：cetos6.5

软件：mysql-5.5.32.tar.gz

二、实验步骤

1.1 安装cmake软件

tar xf cmake-2.8.8.tar.gz

cd cmake-2.8.8

./configure

gmake

gmake install

1.2 创建用户和组及其安装mysql依赖包

groupadd mysql

useradd mysql -s /sbin/nologin -M msyql

yum -y install ncurses-devel

1.3 解压编译安装mysql

tar xf mysql-5.5.32.tar.gz

cd mysql-5.5.32.tar.gz

cmake . -DCMAKE\_INSTALL\_PREFIX=/application/mysql-5.5.32 \\  
\-DMYSQL\_DATADIR=/application/mysql-5.5.32/data \\  
\-DMYSQL\_UNIX\_ADDR=/application/mysql-5.5.32/tmp/mysql.sock \\  
\-DDEFAULT\_CHARSET=utf8 \\  
\-DDEFAULT\_COLLATION=utf8\_general\_ci \\  
\-DEXTRA\_CHARSETS=gbk,gb2312,utf8,ascii \\  
\-DENABLED\_LOCAL\_INFILE=ON \\  
\-DWITH\_INNOBASE\_STORAGE\_ENGINE=1 \\  
\-DWITH\_FEDERATED\_STORAGE\_ENGINE=1 \\  
\-DWITH\_BLACKHOLE\_STORAGE\_ENGINE=1 \\  
\-DWITHOUT\_EXAMPLE\_STORAGE\_ENGINE=1 \\  
\-DWITHOUT\_PARTITION\_STORAGE\_ENGINE=1 \\  
\-DWITH\_FAST\_MUTEXES=1 \\  
\-DWITH\_ZLIB=bundled \\  
\-DENABLED\_LOCAL\_INFILE=1 \\  
\-DWITH\_READLINE=1 \\  
\-DWITH\_EMBEDDED\_SERVER=1 \\  
\-DWITH\_DEBUG=0

make && make install

1.4 配置环境变量写入/etc/profile文件中

PATH="/application/mysql/bin:$PATH"

1.5 创建多实例目录启动脚本配置文件及其授权

/data/  
├── 3306  
│ ├── data  
│ ├── my.cnf  
│ └── mysql  
└── 3307  
├── data  
├── my.cnf  
└── mysql

chown -R mysql.mysql /data/

find /data/ -type f -name "mysql"|xargs chmod +x

/data/3306/mysql start ---启动mysql进程

/data/3307/mysql start ---启动mysql进程

1.6 通过socket多实例方式登录mysql

mysql -S /data/3306/mysql.sock

mysql -S /data/3307/mysql.sock

1.7 修改密码

mysqladmin -uroot -S /data/3306/mysql.sock password '123'  
mysqladmin -uroot -S /data/3307/mysql.sock password '123'

1.8 改密码后的登录方式

mysql -uroot -p -S /data/3306/mysql.sock  
  
mysql -uroot -p -S /data/3307/mysql.sock

1.9 实现登录成功
