<p>
</p>
<p>
<strong>1、配置防火墙，开启80端口、3306端口</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_408447">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">vi /etc/sysconfig/iptables</code>
</div>
<div class="line number2 index1 alt1">
<code class="plain plain">-a rh-firewall-1-input -m state --state new -m tcp -p tcp --dport 80 -j accept</code>
</div>
<div class="line number3 index2 alt2">
<code class="plain plain">-a rh-firewall-1-input -m state --state new -m tcp -p tcp --dport 3306 -j accept</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
:wq! #保存退出</p>
<p>
添加好规则后的防火墙配置文件如下图所示：</p>

<p>
/etc/init.d/iptables restart #重启防火墙使配置生效</p>
<p>
<strong>2、关闭selinux</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_190883">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
<div class="line number4 index3 alt1">
4</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">vi /etc/selinux/config</code>
</div>
<div class="line number2 index1 alt1">
<code class="plain plain">#selinux=enforcing #注释掉</code>
</div>
<div class="line number3 index2 alt2">
<code class="plain plain">#selinuxtype=targeted #注释掉</code>
</div>
<div class="line number4 index3 alt1">
<code class="plain plain">selinux=disabled #增加</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
:wq! #保存退出<br>
setenforce 0 #使配置立即生效</p>
<p>
<strong>3、添加第三方yum源</strong></p>
<p>
centos默认yum源软件版本太低了，要安装最新版本的lamp，这里使用第三方yum源<br>
wget http://www.atomicorp.com/installers/atomic #下载，首先使用默认yum源安装wget命令 yum install wget<br>
sh ./atomic #安装<br>
yum clean all #清除当前yum缓存<br>
yum makecache #缓存yum源中的软件包信息<br>
yum repolist #列出yum源中可用的软件包</p>
<p>
<strong>安装篇：</strong></p>
<p>
<strong>一、安装apache</strong><br>
yum install httpd #根据提示，输入y安装即可成功安装<br>
/etc/init.d/httpd start #启动apache<br>
备注：apache启动之后会提示错误：</p>
<p>
httpd:httpd: could not reliably determine the server's fully qualif domain name, using ::1 for servername</p>
<p>
<strong>解决办法：</strong></p>
<p>
vi /etc/httpd/conf/httpd.conf #编辑<br>
servername www.example.com:80 #去掉前面的注释</p>
<p>
:wq! #保存退出<br>
chkconfig httpd on #设为开机启动<br>
/etc/init.d/httpd restart #重启apache</p>
<p>
在浏览器中打开服务器ip地址，会看到下面的界面，说明安装成功。</p>
<p>

<p>
<strong>二、安装mysql</strong></p>
<p>
1、安装mysql</p>
<p>
yum install mysql mysql-server #询问是否要安装，输入y即可自动安装,直到安装完成</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="CentOS 5.11服务器安装配置LAMP服务器(Apache+PHP5+MySQL)" alt="CentOS 5.11服务器安装配置LAMP服务器(Apache+PHP5+MySQL)" height="381" src="https://zhuji.jb51.net/uploads/img/202305/994985cd7468c45af7f7aebb579d376b.jpg" width="636"></p>
<p>
/etc/init.d/mysqld start #启动mysql</p>
<p>
chkconfig mysqld on #设为开机启动</p>
<p>
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf #拷贝配置文件（注意：如果/etc目录下面默认有一个my.cnf，直接覆盖即可）</p>
<p>
/etc/init.d/mysqld start #启动</p>
<p>
2、为root账户设置密码</p>
<p>
mysql_secure_installation</p>
<p>
回车，根据提示输入y</p>
<p>
输入2次密码，回车</p>
<p>
根据提示一路输入y</p>
<p>
最后出现：thanks for using mysql!</p>
<p>
mysql密码设置完成，重新启动 mysql：</p>
<p>
/etc/init.d/mysqld stop #停止</p>
<p>
/etc/init.d/mysqld restart #重启</p>
<p>
<strong>三、安装php</strong></p>
<p>
<strong>1、安装php</strong></p>
<p>
yum install php #根据提示输入y直到安装完成</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="CentOS 5.11服务器安装配置LAMP服务器(Apache+PHP5+MySQL)" alt="CentOS 5.11服务器安装配置LAMP服务器(Apache+PHP5+MySQL)" height="381" src="https://zhuji.jb51.net/uploads/img/202305/1f2f122c8ff522a6ca8edc86cd968163.jpg" width="640"></p>
<p>
2、安装php组件，使php支持mysql</p>
<p>
yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt</p>
<p>
这里选择以上安装包进行安装</p>
<p>
根据提示输入y回车</p>
<p>
/etc/init.d/mysqld restart #重启mysql</p>
<p>
/etc/init.d/httpd restart #重启apche</p>
<p>

<strong>二、php配置</strong></p>

#列出php可以禁用的函数，如果某些程序需要用到这个函数，可以删除，取消禁用。<br>
expose_php = off #禁止显示php版本的信息<br>
short_open_tag = on #在229行支持php短标签<br>
open_basedir = .:/tmp/ #在380行 设置表示允许访问当前目录(即php脚本文件所在之目录)和/tmp/目录,可以防止php木马跨站,如果改了之后安装程序有问题(例如：织梦内容管理系统)，可以注销此行，或者直接写上程序的目录/data/www.osyunwei.com/:/tmp/<br>
:wq! #保存退出</p>
<p>
/etc/init.d/mysqld restart #重启mysql<br>
