今天先把linux自带的mysql删除后，安装新版本的mysql。
安装mysql时候出现错误MySQL conflicts with mysql-5.0.77-4.el5_6.6.x86_64，如下图所示:
[root@localhost OMS]# rpm -ivh MySQL-server-advanced-5.5.8-1.rhel5.i386.rpm error: Failed dependencies: MySQL conflicts with mysql-5.0.77-4.el5_6.6.x86_64 MySQL conflicts with mysql-5.0.77-4.el5_6.6.i386
后查资料，用rpm -e confictcompoent -- nodeps解决。如下举例说明：
[root@localhost OMS]# rpm -e mysql-5.0.77-4.el5_6.6.x86_64 --nodeps [root@localhost OMS]# rpm -e mysql-5.0.77-4.el5_6.6.i386 --nodeps
然后安装就顺利了：
[root@localhost OMS]# rpm -ivh MySQL-server-advanced-5.5.8-1.rhel5.i386.rpm Preparing... ########################################### [100%] 1:MySQL-server-advanced ########################################### [100%] 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 localhost.localdomain 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 with the /usr/bin/mysqlbug script!
