[跟我學中小企業架構部署]之三：數據庫多實例部署

DB1  DB2 部署
所需軟件：
mysql-5.0.56.tar.gz

安裝mysql

cd /root/tools

創建mysql帳號：

groupadd mysql
useradd -g mysql -M -s /sbin/nologin mysql
tar zxvf mysql-5.0.56.tar.gz
cd mysql-5.0.56
./configure \
--prefix=/usr/local/mysql \
--enable-assembler \
--with-extra-charsets=complex \
--enable-thread-safe-client \
--with-big-tables \
--with-readline \
--with-ssl \
--with-embedded-server \
--enable-local-infile \
--with-plugins=partition,innobase \
--with-plugin-PLUGIN \
--with-mysqld-ldflags=-all-static \
--with-client-ldflags=-all-static
make && make install
cd ..

創建數據目錄

mkdir -p /data/3306/data
mkdir -p /data/3307/data
chown -R mysql:mysql /data/3306
chown -R mysql:mysql /data/3307

建立3306,3307 my.cnf配置文件

vi /data/3306/my.cnf
vi /data/3307/my.cnf

my.cnf內容：(3307 my.cnf就是3306 批量替換3307就好)

#/data/3306/my.cnf
[client]
port            = 3306
socket          = /data/3306/mysql.sock
[mysql]

[mysqldump]
quick
max_allowed_packet = 2M

[mysqld_safe]
log-error=/data/3306/mysql_err.log
pid-file=/data/3306/mysqld.pid

批量替換方法：

sed -i "s/3306/3307/g"  /data/3306/my.cnf  >/data/3307/my.cnf

改變my.cnf配置文件的所有權

chown -R mysql:mysql /data/3306/my.cnf
chown -R mysql:mysql /data/3307/my.cnf

建立mysql啓動腳本

vi /data/3306/mysql
vi /data/3307/mysql

mysql 內容: (3307的mysql需把port改爲3307)

啓動數據庫

/data/3306/mysql start
/data/3307/mysql start

添加爲系統自啓動

echo "/data/3306/mysql start" >>/etc/rc.local
echo "/data/3307/mysql start" >>/etc/rc.local

用 netstat –ant 命令查看mysql端口，若看到下圖標記的端口，即MYSQL安裝成功！

訪問方法(安裝完初始無密碼)：

 

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

更改root密碼

/usr/local/mysql/bin/mysqladmin -u root password 'elain' -S /data/3306/mysql.sock
/usr/local/mysql/bin/mysqladmin -u root password 'elain' -S /data/3307/mysql.sock

登錄MYSQL

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

清理掉系統默認（標記的）的多餘的mysql用戶 3306,3307

select user,host from mysql.user;

 刪除無用帳號

drop user ''@'db1';
drop user ''@'localhost';
drop user 'root'@'db1';

3307同理
處理後結果：
 

到此，MYSQL 安裝完成，DB1 DB2上安裝完全相同！！
