CentOS5.5使用yum來安裝LAMP

今天用yum方法搭建起了個LAMP環境，中間遇到了很多問題，經過google和各位前輩的幫助，終於將環境搭建起來，現在把完整的步驟記錄下來，

1.  換源，sohu的相當好用。

1.1備份CentOS-Base.repo

cd /etc/yum.repos.d/
cp CentOS-Base.repo CentOS-Base.repo.bak
1.2替換源

用vi打開CentOS-Base.repo，並將內容清空，然後將下面的內容複製進去，並保存。

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

#additional packages that may be useful

1.3更新一下。

yum -y update

2.  用yum安裝Apache,Mysql,PHP.

2.1安裝Apache

yum install httpd httpd-devel

安裝完成後，用/etc/init.d/httpd start 啓動apache

設爲開機啓動:chkconfig httpd on

2.2 安裝mysql

2.2.1 yum install mysql mysql-server mysql-devel

         同樣，完成後，用/etc/init.d/mysqld start 啓動mysql

2.2.2 設置mysql密碼

         mysql> USE mysql;
         mysql> UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';
         mysql> FLUSH PRIVILEGES;
2.2.3 允許遠程登錄

         mysql -u root -p
         Enter Password: <your new password>

         mysql&gt;GRANT ALL PRIVILEGES ON *.* TO '用戶名'@'%' IDENTIFIED BY '密碼' WITH GRANT OPTION;

         完成後就能用mysql-front遠程管理mysql了。

2.2.4 設爲開機啓動

         chkconfig mysqld on

3.  安裝php

yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml

/etc/init.d/httpd start

4.  測試一下

在/var/www/html/新建個test.php文件，將以下內容寫入，然後保存。

<?

phpinfo();

?>

然後在客戶端瀏覽器裏打開http://serverip/test.php，若能成功顯示，則表示安裝成功。        

至此，安裝完畢。感慨，yum真是太好用了。
