无法登陆mysql服务器
我在vps上搭建了一个apache+mysql+php的环境，然后安装phpcms，在进行到第五步 账号设置时，配好创建的用户和数据后，显示“无法连接数据库服务器，请检查配置”。
然后我安装了phpMyAdmin测试是否能连接mysql，用创建的一般账户登陆
结果显示“#1045 无法登陆MySQL服务器”
用root登陆显示“2002无法登陆MySQL服务器”
我已经查了网上，然后把php.ini session.auto_start 改为1。重启服务，然后我试了下这次普通用户登陆，显示的也是“2002无法登陆MySQL服务器”。
请问我怎么配置才能使其顺利连上mysql呢
php 版本是5.4，自行编译集成mysql httpd扩展。
httpd mysql是yum安装，mysql版本是5.0.95,httpd 是2.2.3
版本查询 php-mysql-5.1.6-43.el5_10

我试过了，没有用
尝试用 root 用户连接
你现在命令行直接直接命令看看能不能连上
mysql -uroot -p
你的mysql启动了吗？
先启动你的mysql（也可设置为开机自启动）
然后如楼上所说命令行下链接或者用phpMyAdmin连接也可以甚至也可以用你的程序去连接测试一下！
首先确保你的mysql是否安装正确，可查看3306端口是否开启.
然后确定是否能通过命令或者工具连接mysql,如果显示连接错误，可查看错误日志,mysql配置文件里可以找到错误日志的路径。
再确认你的php是否加载上mysql,可查看phpinfo()函数。
你确定是 "2002无法登陆MySQL服务器" 这个错误么,
我上午的是 2003无响应. 然后我到 安装目录下的 bin 目录手动点击了 mysql.exe 就好了
还有1045错误是 用户名或者密码错误!
已解决，是localhost导致的。用ip登录即解决
