对于刚接触linux的同学们，安装mysql可能是一件不能顺利的事，今天就在linux上安装mysql给大家一个详细安装过程：
第一步：mysq安装
服务端：MySQL-server-community-5.1.44-1.rhel4.i386.rpm
客户端：MySQL-client-community-5.1.44-1.rhel4.i386.rpm
1、rpm -ivh MySQL-server-community-5.1.44-1.rhel4.i386.rpm
2、rpm -ivh MySQL-client-community-5.1.44-1.rhel4.i386.rpm
顺利的情况下，这种方式是可以顺利完成mysql安装的，注意安装顺序，先安装server，在安装client。
但是，如果安装出现错误，报提示缺少依赖包，就可以选择yum方式安装，方法如下：
1、yum install MySQL-server-community-5.1.44-1.rhel4.i386.rpm
2、rpm -ivh MySQL-client-community-5.1.44-1.rhel4.i386.rpm
yum方式安装，好处就是安装时会下载并且安装对应的依赖包，不需要我们在自己下载并且安装。
执行上面两种方式，mysql已经可以在linux上安装完成了。
第二步：安装后出现问题及解决方法
安装过程问题：包冲突

删除mysql-libs
[root@localhost ~]# yum remove mysql-libs
再次重新安装第一步方法进行安装。
安装完成后，出现问题
mysql安装完成后，service mysql start，命令启动mysql，显示启动成功。
再次，录入mysql -uroot -p，执行命令，输入用户名和密码都是提示报错：
[root@centos-server01 soft]# service mysql start;
Starting MySQL. SUCCESS!
[root@centos-server01 soft]# msyql
-bash: msyql: command not found
[root@centos-server01 soft]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
解决方法：
# service mysql stop;
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root' and host='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
# service mysql start
# mysql -uroot -p
