千家信息网最后更新 2025年01月20日Linux环境MySQL5.6安装实践MySQL的安装相对于Oracle来说非常简单，个人觉得与TimesTen的安装配置更为接近，而且后面的Master-Slave或Master-Master集群配置更为简单，甚至比TimesTen的ASP/Active-Active/Active-Standby配置都比TimesTen还要简单，不过MySQL涉及的初始化参数还是比较多,初始化参数配置不合理MySQL将很难启动，这次安装MySQL感觉比十年前第一次安装Oracle RAC还折腾，百度了一圈感觉网上的步骤清晰一点的都是使用cmake这个包来安装，所以这里纪录一下安装步骤，或许有对初次接触MySQL的兄弟会有帮助。
安装步骤：
1、安装MySQL数据库软件rpm包
2、配置MySQL数据库参数文件my.cnf
3、初始化MySQL数据库实例
4、启动MySQL服务进程mysqld
5、修改登录密码和检查数据库参数
一、操作系统环境
IP:192.168.100.71 tony7
操作系统版本：
# uname -a
Linux tony7 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

mysql-server-5.1.47-4.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps mysql-5.1.47-4.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps perl-DBD-MySQL-4.013-3.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps mysql-libs-5.1.47-4.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps qt-mysql-4.6.2-16.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps mysql-server-5.1.47-4.el6.x86_64
如果已安装，则需要删除已安装的数据库，使用以下命令来删除数据库
删除命令：rpm -e --nodeps 包名
( rpm -ev mysql-4.1.12-3.RHEL4.1 )
删除老版本mysql的开发头文件和库
命令：rm -fr /usr/lib/mysql
rm -fr /usr/include/mysql
注意：卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除，如果确定没用后就手工删除
rm -f /etc/my.cnf
rm -fr /var/lib/mysql
二、安装数据库软件
MySQL-server-5.6.28-1.el6.x86_64.rpm
MySQL-client-5.6.28-1.el6.x86_64.rpm
MySQL-devel-5.6.28-1.el6.x86_64.rpm
# rpm -ivh MySQL-server-5.6.28-1.el6.x86_64.rpm

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.

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/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h tony7 password 'new-password'
Alternatively you can run:
/usr/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 ; /usr/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/

五、启动MySQL服务进程mysqld
cp /usr/share/mysql/mysql.server /etc/init.d/mysqld
# service mysqld start
Starting MySQL... SUCCESS!

unix 2 [ ACC ] STREAM LISTENING 21155 11254/mysqld /mysql/data/mysqldata/sock/mysql.sock
六、修改登录密码和检查数据库参数
mysqladmin -u root -h tony7 password 'mysql'
[root@tony7 ~]# mysql -uroot -pmysql -htony7
Warning: Using a password on the command line interface can be insecure.

安装步骤：
1、安装MySQL数据库软件rpm包
2、配置MySQL数据库参数文件my.cnf
3、初始化MySQL数据库实例
4、启动MySQL服务进程mysqld
5、修改登录密码和检查数据库参数
一、操作系统环境
IP:192.168.100.71 tony7
操作系统版本：
# uname -a
Linux tony7 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
# free -g

qt-mysql-4.6.2-16.el6.x86_64
mysql-server-5.1.47-4.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps mysql-5.1.47-4.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps perl-DBD-MySQL-4.013-3.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps mysql-libs-5.1.47-4.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps qt-mysql-4.6.2-16.el6.x86_64
[root@tony7 soft]# rpm -e --nodeps mysql-server-5.1.47-4.el6.x86_64
如果已安装，则需要删除已安装的数据库，使用以下命令来删除数据库
删除命令：rpm -e --nodeps 包名
( rpm -ev mysql-4.1.12-3.RHEL4.1 )
删除老版本mysql的开发头文件和库
命令：rm -fr /usr/lib/mysql
rm -fr /usr/include/mysql
注意：卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除，如果确定没用后就手工删除
rm -f /etc/my.cnf
rm -fr /var/lib/mysql
二、安装数据库软件
MySQL-server-5.6.28-1.el6.x86_64.rpm
MySQL-client-5.6.28-1.el6.x86_64.rpm
MySQL-devel-5.6.28-1.el6.x86_64.rpm
# rpm -ivh MySQL-server-5.6.28-1.el6.x86_64.rpm

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.
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/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

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/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h tony7 password 'new-password'
Alternatively you can run:
/usr/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 ; /usr/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/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
五、启动MySQL服务进程mysqld
cp /usr/share/mysql/mysql.server /etc/init.d/mysqld
# service mysqld start
Starting MySQL... SUCCESS!
# netstat -npl|grep mysql
tcp 0 0 :::3306 :::* LISTEN 11254/mysqld
unix 2 [ ACC ] STREAM LISTENING 21155 11254/mysqld /mysql/data/mysqldata/sock/mysql.sock
六、修改登录密码和检查数据库参数
mysqladmin -u root -h tony7 password 'mysql'
[root@tony7 ~]# mysql -uroot -pmysql -htony7
Warning: Using a password on the command line interface can be insecure.
