CentOS 6.3安装配置nginx+php+mysql
<p><strong>准备篇</strong></p>
<p>
<span>1.配置防火墙，开启80端口、3306端口</span></p>
<p>
1 vim /etc/sysconfig/iptables<br>
2 -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT #允许80端口通过防火墙<br>
3 -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT #允许3306端口通过防火墙</p>
<p>
<code>service iptables restart</code> #重启防火墙，使配置生效</p>
<p>
<span>2.关闭SELINUX</span>（这个和服务器安全相关，先关闭。相关介绍：https://wiki.centos.org/zh/HowTos/SELinux）</p>

<span>3.安装第三方源</span></p>
<p>
1)安装EPEL仓库</p>
<p>
<code>yum install -y epel-release</code></p>
<p>
如果以上命令不起作用：</p>
<p>
CentOS/RHEL 7</p>
<p>
rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm</p>
<p>
CentOS/RHEL 6</p>
<p>
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm</p>
<p>
2)安装IUS仓库</p>
<p>
CentOS 6</p>
<p>
rpm -Uvh https://centos6.iuscommunity.org/ius-release.rpm</p>
<p>
CentOS 7</p>
<p>
rpm -Uvh https://centos7.iuscommunity.org/ius-release.rpm</p>
<p>
<strong>错误处理:</strong></p>
<p>
1.安装IUS仓库出错：curl: (35) SSL connect error。这个问题在RHEL 6.1 -> RHEL 6.4应该都会出现，原因是curl使用了REST API。解决：</p>
<p>
<code>yum update nss</code></p>
<p>
2.结果问题1没解决，出另一个问题：Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again。解决：</p>
<p>
<code>vim /etc/yum.repos.d/CentOS-Base.repo</code></p>
<p>
把有mirrorlist的都注释掉，有baseurl的都去掉注释，然后再进行步骤1，再安装IUS仓库。修改如下：</p>

mysql和php的版本都有些旧，他们都来源于mirrors.163.com这个源。而epel和ius源的软件版本一般比较新。</p>
<p>
使用以下命令列出所有mysql和php的版本：</p>
<p>
<code>yum list mysql* php*</code></p>
<p>
这会列出一大堆像这样的结果，接下来只要选择需要安装的软件版本就好：</p>

<strong>配置篇</strong></p>
<p>
nginx的配置文件是/etc/nginx下的nginx.conf。在nginx.conf文件的最后一行可以看到： include /etc/nginx/conf.d/*.conf; 它把 /etc/nginx/conf.d目录下后缀为.conf的文件都包含进来了，所以只要在/etc/nginx/conf.d/这个目录下配置一个.conf文件就行了。以下是我的配置：</p>
