1. 操作系统
CentOS release 6.2 (Final)
2. 创建用户和组
[root@mymaster1 ~]# groupadd mysql
[root@mymaster1 ~]# useradd -r -g mysqlmysql
3. 解压安装包（解压到你想存储数据库数据的地方）
[root@mymaster1 ~]# cd /data
[root@mymaster1 data]# tar -xzvf /root/mysql_soft/mysql-5.6.19-linux-glibc2.5-x86_64.tar.gz
[root@mymaster1 data]# ln -s mysql-5.6.19-linux-glibc2.5-x86_64 mysql
4. 查看解压情况
[root@mymaster1 data]# ll
总用量 20
lrwxrwxrwx. 1 root root 34 6月 27 15:31 mysql -> mysql-5.6.19-linux-glibc2.5-x86_64
drwxr-xr-x. 13 rootroot 4096 6月 27 15:31 mysql-5.6.19-linux-glibc2.5-x86_64
5. 修改文件夹所属用户和组为mysql：
[root@mymaster1 data]# cd mysql
[root@mymaster1 mysql]# chown -R mysql:mysql .
6. 安装数据库，数据存放目录为/data/mysql/data
[root@mymaster1 mysql]#scripts/mysql_install_db --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data
WARNING: The host‘mymaster1.localdomain‘ could not be looked up with /data/mysql/bin/resolveip.
This probably means thatyour libc libraries are not 100 % compatible
with this binary MySQLversion. The MySQL daemon, mysqld, should work
normally with the exceptionthat host name resolving will not work.
This means that youshould use IP addresses instead of hostnames
when specifying MySQLprivileges !
当出现上面警告时，解决方法是：在/etc/hosts配置文件中增加IP地址和主机名的映射
如
[root@mymaster1 Packages]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
IP地址 mymaster1.localdomain
正确的提示信息如下：

To start mysqld at boot time you have tocopy
support-files/mysql.server to the rightplace for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THEMySQL root USER !
To do so, start the server, then issue thefollowing commands:
/data/mysql/bin/mysqladmin -u root password ‘new-password‘
/data/mysql/bin/mysqladmin -u root -h mymaster1.localdomain password‘new-password‘
Alternatively you can run:
/data/mysql/bin/mysql_secure_installation
which will also give you the option ofremoving the test
databases and anonymous user created bydefault. This is
strongly recommended for productionservers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd. ; /data/mysql/bin/mysqld_safe &
You can test the MySQL daemon withmysql-test-run.pl
cdmysql-test ; perl mysql-test-run.pl
Please report any problems athttp://bugs.mysql.com/
The latest information about MySQL isavailable on the web at

Support MySQL by buying support/licenses athttp://shop.mysql.com
New default config file was created as/data/mysql/my.cnf and
will be used by default by the server whenyou start it.
You may edit this file to change serversettings
7. 修改相关目录权限，提高安全性：
[root@mymaster1 mysql]# chown -R root .
[root@mymaster1 mysql]# chown -R mysql data
8. 配置MySQL服务为主机服务，即能用service mysql start启动服务
[root@mymaster1 mysql]# cpsupport-files/mysql.server /etc/init.d/mysql
[root@mymaster1 mysql]# vi /etc/init.d/mysql
把下面的
basedir=
datadir=
修改为
basedir=/data/mysql
datadir=/data/mysql/data
9. 启动数据库
[root@mymaster1 mysql]# service mysql start
Starting MySQL[确定]
10. 修改数据库root密码
[root@mymaster1 mysql]#/data/mysql/bin/mysqladmin -u root password ‘wengjixi‘
[root@mymaster1 mysql]#/data/mysql/bin/mysqladmin -u root -h mymaster1.localdomain password ‘wengjixi‘
11. 修改环境变量，把mysql执行文件路径添加到环境变量中
[root@mymaster1 mysql]# vi /etc/profile
PATH=$PATH:/data/mysql/bin
export PATH
[root@mymaster1 mysql]# source /etc/profile
12. 测试登录
[root@mymaster1 mysql]# mysql -u root -p
Enter password:
