准备篇
1.配置防火墙，开启80端口、3306端口
1 vim /etc/sysconfig/iptables 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 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
service iptables restart #重启防火墙，使配置生效
2.关闭SELINUX（这个和服务器安全相关，先关闭。相关介绍：https://wiki.centos.org/zh/HowTos/SELinux）
vim /etc/selinux/config #SELINUX=enforcing #注释掉 #SELINUXTYPE=targeted #注释掉 SELINUX=disabled #增加 :wq #保存退出
shutdown -r now #重启系统
3.安装第三方源
1)安装EPEL仓库
yum install -y epel-release
如果以上命令不起作用：
- CentOS/RHEL 7
rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
- CentOS/RHEL 6
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
2)安装IUS仓库
- CentOS 6
rpm -Uvh https://centos6.iuscommunity.org/ius-release.rpm
- CentOS 7
rpm -Uvh https://centos7.iuscommunity.org/ius-release.rpm
错误处理:
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：
yum update nss
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：
vim /etc/yum.repos.d/CentOS-Base.repo
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：
[epel] name=Extra Packages for Enterprise Linux 6 - $basearch baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 [epel-debuginfo] name=Extra Packages for Enterprise Linux 6 - $basearch - Debug baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch/debug #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-6&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 gpgcheck=1 [epel-source] name=Extra Packages for Enterprise Linux 6 - $basearch - Source baseurl=http://download.fedoraproject.org/pub/epel/6/SRPMS #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-6&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 gpgcheck=1
查看仓库列表，看看是否安装成功了：
yum repolist
ius | 2.3 kB 00:00 ius/primary_db | 183 kB 00:00 repo id repo name status base CentOS-6 - Base 5,062 epel Extra Packages for Enterprise Linux 6 - i386 9,992 extras CentOS-6 - Extras 39 ius IUS Community Packages for Enterprise Linux 6 - i386 329 updates CentOS-6 - Updates 382 repolist: 15,804
安装仓库成功。接下来安装nginx,mysql,php。

安装篇
查看即将要安装的软件的版本：
yum list nginx mysql php
结果：
[[email protected] ~]# yum list nginx mysql php
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: mirrors.163.com
* extras: mirrors.163.com
* ius: hkg.mirror.rackspace.com
* updates: mirrors.163.com
Available Packages
mysql.i686 5.1.73-7.el6 base
nginx.i686 1.10.1-1.el6 epel
php.i686 5.3.3-48.el6_8 updates
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。
使用以下命令列出所有mysql和php的版本：
yum list mysql* php*
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：
软件名字 软件版本 #软件所在仓库php56u.i686 5.6.26-1.ius.centos6 ius mysql55.i686 5.5.52-1.ius.centos6 ius
安装nginx
yum remove httpd* php* #删除系统自带的软件包 yum install nginx #安装nginx 根据提示输入y进行安装 chkconfig nginx on #设置nginx开机启动 service nginx start #启动nginx
安装MySQL
yum remove mysql* #删除系统已经安装的mysql yum list mysql* #列出mysql所有版本，找到要安装的版本的名字 yum install mysql57u* #我安装的是mysql5.7.15。输入Y即可自动安装,直到安装完成 service mysqld start #启动MySQL chkconfig mysqld on #设为开机启动
安装PHP
yum install php56u-fpm php56u-mbstring php56u-bcmath php56u-mcrypt php56u-xmlrpc php56u-pdo php56u-xml php56u-xmlrpc php56u-mysqlnd php56u-gd php56u-opcache #安装php5.6及扩展 chkconfig php-fpm on #设置php-fpm开机启动 service php-fpm start #启动php-fpm

配置篇
- 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：
#
# The default server
#
server {
listen 80;
server_name n.com;
root /usr/share/nginx/html;
index index.php index.html;
# Load configuration files for the default server block.
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ .*\.(php)?$ {
expires -1s;
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include fastcgi_params;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass 127.0.0.1:9000;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
重启nginx：
service nginx restart
在/usr/share/nginx/html/这个目录下新建一个index.php
cd /usr/share/nginx/html #进入html目录 vim index.php #新建index.php，加上phpinfo();
浏览器访问：centos的ip地址/index.php。完成！
