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 - $basearchbaseurl=http://download.fedoraproject.org/pub/epel/6/$basearch#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearchfailovermethod=priorityenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6[epel-debuginfo]name=Extra Packages for Enterprise Linux 6 - $basearch - Debugbaseurl=http://download.fedoraproject.org/pub/epel/6/$basearch/debug#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-6&arch=$basearchfailovermethod=priorityenabled=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6gpgcheck=1[epel-source]name=Extra Packages for Enterprise Linux 6 - $basearch - Sourcebaseurl=http://download.fedoraproject.org/pub/epel/6/SRPMS#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-6&arch=$basearchfailovermethod=priorityenabled=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6gpgcheck=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 statusbase CentOS-6 - Base 5,062epel Extra Packages for Enterprise Linux 6 - i386 9,992extras CentOS-6 - Extras 39ius IUS Community Packages for Enterprise Linux 6 - i386 329updates CentOS-6 - Updates 382repolist: 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：
[root@localhost ~]# yum list nginx mysql phpLoaded plugins: fastestmirror, securityLoading mirror speeds from cached hostfile* base: mirrors.163.com* extras: mirrors.163.com* ius: hkg.mirror.rackspace.com* updates: mirrors.163.comAvailable 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nginxyum 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MySQLyum remove mysql* #删除系统已经安装的mysqlyum 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MySQLchkconfig 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！
