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]# 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。
