1首先查看是否已经装有mysql命令：rpm –qa|grep –i mysql如果有的话，用命令卸载（删除）命令：rpm –e --nodeps 包名2.上传安装文件MySQL-client-5.5.8-1.rhel5.i386.rpmMySQL-server-5.5.8-1.rhel4.i386.rpm运行命令安装：rpm –ivh MySQL-server-5.5.8-1.rhel4.i386.rpm成功界面：[root@localhost liuhaisheng]# rpm -ivhMySQL-server-5.5.8-1.rhel4.i386.rpmPreparing...########################################### [100%]1:MySQL-server########################################### [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_installationwhich will also give you the option of removing the test databases and anonymous user created by default.

注意：这个MySQL文件在/usr/bin目录下，与后面讲的启动文件/etc/init.d/MySQL不是一个文件。

如果没有，就直接删除。

如果是./configure --prefix指定了目录用 rm -rf 目录名删除-------------------------------------------------------------[root@localhost ~]# cd /usr/local/src/mysql-5.1.45[root@localhost mysql-5.1.45]# make uninstall[root@localhost mysql-5.1.45]# cd ..[root@localhost src]# rm -rf mysql-5.1.45[root@localhost src]# cd ..[root@localhost local]# lsbin etc games include lib libexec mysql sbin share src web[root@localhost local]# rm -rf mysql/[root@localhost local]# lsbin etc games include lib libexec sbin share src web[root@localhost local]#-------------------------------------------------------------二.rpm方式安装的卸载方法：查看是否安装mysql的命令rpm -qa | grep mysql然后逐个使用 rpm -e mysq-* 卸载如果出现error: Failed dependencies:libmysqlclient.so.10 is needed by (installed)libdbi-dbd-mysql-0.6.5-10.RHEL4.1.i386libmysqlclient.so.10 is needed by (installed)MySQL-python-1.0.0-1.RHEL4.1.i386libmysqlclient.so.10 is needed by (installed)MyODBC-2.50.39-21.RHEL4.1.i386libmysqlclient.so.10 is needed by (installed) qt-MySQL-3.3.3-9.3.i386 mysqlclient10 is needed by (installed)MySQL-python-1.0.0-1.RHEL4.1.i386mysqlclient10 = 3.23.58-4.RHEL4.1 is needed by (installed) mysqlclient10-devel-3.23.58-4.RHEL4.1.i386时，使用 --nodeps 参数，如：rpm -e mysqlclient10-devel-3.23.58-4.RHEL4.1 --nodepsrpm -e mysqlclient10-3.23.58-4.RHEL4.1 --nodeps网络其他记录：本人未验证启动MySQL/etc/init.d/MySQL start 或service MySQL start停止MySQL/etc/init.d/MySQL stop 或service MySQL stop到此，MySQL服务就安装配置完成。

安装MySQL客户端rpm -ivh MySQL-client-4.0.14-0.i386.rpmMySQL安装好后目录结构如下：工具程序在/usr/bin目录中－－－ls /usr/bin/MySQL*服务器程序/usr/sbin/MySQLd数据目录/var/lib/MySQL默认情况下MySQL将错误日志文件、二进制日志文件及进程文件写在/var/lib/MySQL目录中,如localhost.err、localhost.pid、localhost-bin.001等要改变这些情况可以修改/etc/f文件如将日志文件写在/var/log目录中，可以在f文件中加入下面两行：[MySQLd_safe]err-log = /var/log/MySQLd.log有个实用程序/usr/bin/MySQL_install_db，该程序可以用来初始化MySQL数据库，即创建/var/l og/MySQL目录，及创建MySQL数据库(MySQL授权表等信息)及test数据库(空库),如果不小心删除了/var/log/MySQL目录可以通过该程序来初始化.卸载MySQLrpm -qa|grep -i MySQLrpm -ev MySQL-server-4.0.14-0 MySQL-client-4.0.14-0卸载后/var/lib/MySQL中的数据及/etc/f不会删除，如果确定没用后就手工删除rm -f /etc/frm -rf /var/lib/MySQLMySQL 1130错误解决方法:通过MySQL-Front或MySQL administrator连接MySQL的时候发生的这个错误ERROR 1130: Host ***.***.***.*** is not allowed to connect to this MySQL server说明所连接的用户帐号没有远程连接的权限，只能在本机(localhost)登录。
