tar -xvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
2.拷贝安装包和配置文件(如果没有特殊情况,将安装包解压放置在该目录)
cp -rf MysqL /usr/local/MysqL
cp -rf my5.6.cnf /etc/my.cnf
3.创建MysqL用户
useradd MysqL
4.添加数据目录
mkdir -p /home/MysqL3306/MysqL3306
mkdir -p /home/MysqL3306/logs
5.修改目录权限
chown MysqL:MysqL -R /home/MysqL3306
6.修改配置文件
socket = /tmp/MysqL.sock(socket文件存放位置)
datadir = /home/MysqL3306/MysqL3306(数据文件存放目录)
server-id = 12013306(设置serverid 命名规则:ip后两位+端口号)
port = 3306(启动端口)
innodb_buffer_pool_size = 1024M(innodb buffer pool大小)
*如果是核心节点单实例 配置成系统总内存的75%左右,如果不是核心节点则按照具体业务压力来设置
7.初始化数据库(确认2个OK)

- OK
- To start MysqLd at boot time you have to copy
- support-files/MysqL.server to the right place for your system
- PLEASE REMEMBER TO SET A PASSWORD FOR THE MysqL root USER !
- To do so, start the server, then issue the following commands:
- /usr/local/MysqL/bin/MysqLadmin -u root password 'new-password'
- /usr/local/MysqL/bin/MysqLadmin -u root -h MysqL5.6 password 'new-password'
- Alternatively you can run:
- /usr/local/MysqL/bin/MysqL_secure_installation
- which will also give you the option of removing the test
- databases and anonymous user created by default. This is
- strongly recommended for production servers.
- See the manual for more instructions.
- You can start the MysqL daemon with:
- cd . ; /usr/local/MysqL/bin/MysqLd_safe &
- You can test the MysqL daemon with MysqL-test-run.pl
- cd MysqL-test ; perl MysqL-test-run.pl
- Please report any problems at http://bugs.MysqL.com/
- The latest information about MysqL is available on the web at
- http://www.MysqL.com
- Support MysqL by buying support/licenses at http://shop.MysqL.com
- New default config file was created as /usr/local/MysqL/my.cnf and
- will be used by default by the server when you start it.
- You may edit this file to change server settings
- WARNING: Default config file /etc/my.cnf exists on the system
- This file will be read by default by the MysqL server
- If you do not want to use this, either remove it, or use the
- --defaults-file argument to MysqLd_safe when starting the server
