我本来只是为了搭建简单的LAMP环境，亲自动手，却发现有这么多的问题会发生。(by default7#zbphp.com)

很多地方给的安装Mysql的提示是通过yum一键安装。shell命令如下：

yum install mysql

yum install mysql-server

yum install mysql-devel

但是，这个命令安装的mysql版本很旧，5.1.0x版本的，官网的Mysql已经是 5.6.x版本了。太旧了，记得08年的时候就出了 5.1的版本了。

坚持安装最新版本的，在MYSQL官网下载rpm-.tar安装包，300MB左右。linux64。

[root@localhost mysqlinstall]# ls 
MySQL-client-5.6.19-1.linux_glibc2.5.x86_64.rpm
MySQL-devel-5.6.19-1.linux_glibc2.5.x86_64.rpm
MySQL-embedded-5.6.19-1.linux_glibc2.5.x86_64.rpm
MySQL-server-5.6.19-1.linux_glibc2.5.x86_64.rpm
MySQL-shared-5.6.19-1.linux_glibc2.5.x86_64.rpm
MySQL-shared-compat-5.6.19-1.linux_glibc2.5.x86_64.rpm
MySQL-test-5.6.19-1.linux_glibc2.5.x86_64.rpm
[root@localhost mysqlinstall]# pwd
/home/default7@zbphp.com/Downloads/mysqlinstall
[root@localhost mysqlinstall]#  

但是按照网上（CSDN博客、blogcn博客）一步步提示来安装但是总是各种问题，各种问题，无法运行。

最后尝试了很多遍终于安装成功，正常运行：

其实我一直不断的重新安装，总是问题，无法启动或者报错，原因在与第一次安装步骤不正确，然后接下来不断的重装。

但是并没有彻底卸载干净。rpm -e Mysql 这个似乎区分大小写，而我一开始直接删除文件夹来卸载，后来用 rpm -e -nodeps mysql来卸载，但是还是有残留。

最后是用的yum remove mysql ,mysql-server,mysql-shared 来卸载，为了卸载干净，之后，将所有文件夹中有mysql的删除掉。然后再重新安装。

修改设置密码，原始密码在/root/这个文件夹里面，ls -a可以看到一个mysql的文件，里面有原始密码：
