本文主要给大家简单讲讲怎么样安装多实例mysql数据库，相关专业术语大家可以上网查查或者找一些相关书籍补充一下，这里就不涉猎了，我们就直奔主题吧，希望怎么样安装多实例mysql数据库这篇文章可以给大家带来一些实际帮助。

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

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

~]#mysql -uroot -p -S /data/3306/mysql.sock
