本文主要給大家簡單講講怎么樣安裝多實例mysql數據庫，相關專業術語大家可以上網查查或者找一些相關書籍補充一下，這里就不涉獵了，我們就直奔主題吧，希望怎么樣安裝多實例mysql數據庫這篇文章可以給大家帶來一些實際幫助。

一、實驗環境

系統：cetos6.5

軟件：mysql-5.5.32.tar.gz  

二、實驗步驟 

1.1 安裝cmake軟件

tar xf cmake-2.8.8.tar.gz

cd cmake-2.8.8

./configure 

gmake

gmake install  

1.2 創建用戶和組及其安裝mysql依賴包

groupadd mysql

useradd mysql -s /sbin/nologin -M msyql

yum -y install ncurses-devel  

1.3 解壓編譯安裝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 配置環境變量寫入/etc/profile文件中

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

1.5 創建多實例目錄啟動腳本配置文件及其授權 

/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  ---啟動mysql進程

/data/3307/mysql start  ---啟動mysql進程

1.6 通過socket多實例方式登錄mysql

mysql -S /data/3306/mysql.sock

mysql -S /data/3307/mysql.sock 

1.7 修改密碼

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

1.8 改密碼后的登錄方式

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