本次安装环境为：

系统：centos 6 X86_X64

内存：不低于4G

mysql 版本：mysql-boost-5.7.18.tar.gz

本文主要讲解在同主机上部署mysql多实例

门户网站应用mysql 多实例场景

百度搜索引擎的数据库就是多实例，一般是从库，列如某个部门的例子，IBM 48核CPU。内存96G，跑3-4个实例；sina 网也是用的多实例，内存48G左右。门户网站使用多实例的目的是配硬件好的服务器，节省idc机柜的空间，同时，跑多实例让硬件资源不浪费，针对一般的服务器最多4个实例即可，1-2两个最合适。

多实例可以是多个配置文件对应多实例也可以一个配置文件对应多个实例

多实例缺点：

1、耦合度太高，一个配置文件不好管理。工作开发和运维的统一原则；降低耦合度

mysql 相关软件包：

yum -y install ncurses-devel libaio-devel cmake

安装需要mysql 需要创建用户和组

useradd mysql -s /sbin/nologin -M

下载mysql 5.7 安装包

wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.18.tar.gz

解压安装包

tar -zxf mysql-boost-5.7.18.tar.gz && cd mysql-5.7.18

删除 /etc/my.cnf

/u01/app/mysql/db/etc

初始化之前需要查看error 日志

cat /data/mysql/mysql-error.log

cd /u01/app/mysql/db

./bin/mysqld --initialize --basedir=/u01/app/mysql/db --datadir=/data/mysql/data --user=mysql
# --initialize-insecure option 使用这个初始化数据库之后不再需要登录后进行alter user

#cat /data/mysql/mysql-error.log

/u01/app/mysql/db/bin/mysqld_safe --skip-grant-tables &

update mysql.user set authentication_string=password(‘123.com‘) where user=‘root‘ and Host = ‘localhost‘;

#启动mysql 服务

/u01/app/mysql/db/support-files/mysql.server restart

##需要重新更改密码否则无法正常使用库

alter user ‘root‘@‘localhost‘ identified by ‘123.com‘;

#设置开机自启动

cp /u01/app/mysql/db/support-files/mysql.server /etc/init.d/mysql.server-5.7

chmod +x /etc/init.d/mysql.server-5.7

chkconfig --addmysql.server-5.7

#设置环境变量

vim ~/.bashrc

#set mysql

NHOME=/u01/app/mysql/db

PATH=$PATH:$NHOME/bin

source ~/.bashrc

mysql 多实例可以写两个不同的配置文件与不同的端口初始化库时候直接更改即可
