Jun 01, 2016 pm 01:01 PM

 

一、安装问题:

首先进入 :http://dev.mysql.com/downloads/repo/yum/ 下载界面,拿到rpm的地址

选择yum下载:

\

2、下载redhat 6 对应的rpm

\

右键另存为 连接地址:

\

在linux 服务器上下载这个rpm服务器:

 

wget http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
Copy after login

本地安装 repository

<code lang="">sudo yum localinstall mysql-community-release-el6-5.noarch.rpm</code>
Copy after login
操作完成后,当前server还没有安装任何的软件。所以我我们还得安装 MySQL Server:

<code lang=""><code lang="">sudo yum install mysql-community-server</code></code>
Copy after login

<code lang="">mysql 的安装路径为: /var/lib/mysql

<code lang="">理论上,这步完成后,就可以启动mysql了。

<code lang=""><code lang=""><code lang="">sudo service mysqld start</code></code></code>
Copy after login
<code lang=""><code lang="">但是,当我启动的时候,我报错了


<code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I0351560-435F.jpg" class="lazy" alt="\" />


<code lang=""><code lang="">查看错误日志:

<code lang=""><code lang=""><code lang=""><code lang="">cat /var/log/mysqld.log</code></code></code></code>
Copy after login

<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I03A620-51A5.jpg" class="lazy" alt="\" />

<code lang=""><code lang=""><code lang="">发现者三个文件是多余的,直接把这些文件删了。重启下就好了,删除路径如下所示:

<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I03RQ0-62U3.jpg" class="lazy" alt="\" />

<code lang=""><code lang=""><code lang="">然后直接登录。(默认的账号和密码都是 root /root)

<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I0401560-M530.jpg" class="lazy" alt="\" />

<code lang=""><code lang=""><code lang="">这就算装好了。

<code lang=""><code lang=""><code lang="">二、远程登录问题

<code lang=""><code lang=""><code lang="">我用第三方远程连接的时候,报错。查了下,发现有两个root用户,其中有一个是绑定本机(127.0.0.1)登录的。

<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I041GZ-U515.jpg" class="lazy" alt="\" />



<code lang=""><code lang=""><code lang="">所以想办法改变所有root的密码:

Copy after login

 

<code lang=""><code lang=""><code lang=""><code lang="">mysql> use mysql;<br> mysql> UPDATE user SET password=password("root") WHERE user='root';<br> mysql> flush privileges;<br> mysql> exit; 然后再登录,就ok了。
