LAMP环境搭建【rpm】+ 实例应用

服务器ip地址 192.168.1.25

lamp  à    linux +apache +mysql +php

1.安装apache服务

[root@localhost ~]# yum install httpd –y

2.安装mysql服务

[root@localhost ~]# yum list all |grep mysql

[root@localhost ~]# yum install mysql mysql-server

3.启动服务

[root@localhost ~]# service mysqld start

[root@localhost ~]# service httpd start

4．设置开机启动

[root@localhost ~]# chkconfig httpd on

[root@localhost ~]# chkconfig mysqld on

5.测试mysql服务

[root@localhost ~]# mysql     

mysql> use mysql; 

mysql> show tables;    ß查看数据库

mysql> \q

[root@localhost ~]# mysqladmin -u root -p password '1234' --登录密码

Enter password:    原始密码为空

[root@localhost ~]# mysql

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

6.重新登录mysql

[root@localhost ~]# mysql -u root –p     

Enter password:

Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql> \q

7.安装php

[root@localhost ~]# yum list all |grep php

[root@localhost ~]# yum install php php-mysql

8.安装完php以后在/etc/httpd/conf.d的目录下新加了php.conf文件

[root@localhost ~]# cd /etc/httpd/conf.d

[root@localhost conf.d]# ll

总计 32

-rw-r--r-- 1 root root 560 2009-02-26 php.conf

-rw-r--r-- 1 root root 566 2009-07-15 proxy_ajp.conf

-rw-r--r-- 1 root root 392 2009-07-15 README

-rw-r--r-- 1 root root 299 2009-07-15 welcome.conf

9.测试php是否安装成功，创建index.php

[root@localhost conf.d]# cd /var/www/html

[root@localhost html]# vim index.php

输入如下：

<?

 phpinfo()

?>

保存退出测试，能够正常访问phpinfo()

10.测试php 能否调用mysql 数据库，修改index.php

[root@localhost html]# vim index.php

<?

 $link=mysql_connect('127.0.0.1','root','1234');

if($link)

echo"it is ok ";

else

echo"it is faild";

?>

 [root@localhost html]# service mysqld restart

关闭mysql  可以看到访问不到

[root@localhost html]# service mysqld stop

[root@localhost html]# service mysqld start                   

搭建完成。
