centos6.5环境通过rpm包安装mysql5.5.51数据库





注意：此方法适用于单独安装数据库的需求，如果在该机器上还需要安装php环境，建议mysql通过编译或yum方式安装





1.查找已经安装的mysql并删除

rpm -qa | grep mysql

mysql-libs-5.1.73-7.el6.x86_64

mysql-5.1.73-7.el6.x86_64





rpm -e mysql-libs-5.1.73-7.el6.x86_64 --nodeps

rpm -e mysql-5.1.73-7.el6.x86_64 --nodeps





2.rpm安装mysql5.5.51

rpm -ivh MySQL-server-5.5.51-1.el6.x86_64.rpm 

rpm -ivh MySQL-client-5.5.51-1.el6.x86_64.rpm 

rpm -ivh MySQL-devel-5.5.51-1.el6.x86_64.rpm 





安装：

 rpm -ivh MySQL-devel-5.5.51-1.el6.x86_64.rpm

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 node2.chinasoft.com 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.





Please report any problems at http://bugs.mysql.com/





[root@node2 ~]# rpm -ivh MySQL-client-5.5.51-1.el6.x86_64.rpm

报错：

error: Failed dependencies:

MySQL-devel conflicts with mysql-devel-5.1.73-7.el6.x86_64

删除原有的mysql5.1

rpm -e mysql-devel-5.1.73-7.el6.x86_64 --nodeps





3.验证是否安装成功

pm -qa|grep -i mysql

MySQL-client-5.5.51-1.el6.x86_64

MySQL-server-5.5.51-1.el6.x86_64

MySQL-devel-5.5.51-1.el6.x86_64





配置文件

cp /usr/share/mysql/my-large.cnf /etc/my.cnf





mkdir /data/mydata

修改配置文件

vim /etc/my.cnf

socket = /data/mydata/mysql.sock

socket = /data/mydata/mysql.sock

datadir=/data/mydata





4.初始化数据库

/usr/bin/mysql_install_db





改变/data/的所有者

chown -R mysql.mysql /data





启动数据库

service mysql start
