centos安裝nginx有兩種方式，分別是yum 安裝和 源碼包 安裝。詳細能夠看這篇文章
yum安裝和源碼包安裝的區別

本網站的後臺用的是yum安裝，相對來說比源碼包安裝要簡單點，基本就一條命令，不過缺點是安裝後的nginx文件比較分散，咱們在修改配置文件的時候常常不知道去哪找，不像源碼包那樣文件基本能夠放在一個路徑下，比較好找。

不過咱們能夠用下面這個命令來查看nginx的安裝位置。

rpm -ql nginx

運行後的結果以下：

/etc/logrotate.d/nginx
/etc/nginx/fastcgi.conf
/etc/nginx/fastcgi.conf.default
/etc/nginx/fastcgi_params
/etc/nginx/fastcgi_params.default
/etc/nginx/koi-utf
/etc/nginx/koi-win
/etc/nginx/mime.types
/etc/nginx/mime.types.default
/etc/nginx/nginx.conf
/etc/nginx/nginx.conf.default
/etc/nginx/scgi_params
/etc/nginx/scgi_params.default
/etc/nginx/uwsgi_params
/etc/nginx/uwsgi_params.default
/etc/nginx/win-utf
/usr/bin/nginx-upgrade
/usr/lib/systemd/system/nginx.service
/usr/lib64/nginx/modules
/usr/sbin/nginx

/usr/share/nginx/html/404.html

/usr/share/vim/vimfiles/ftdetect/nginx.vim
/usr/share/vim/vimfiles/indent/nginx.vim
/usr/share/vim/vimfiles/syntax/nginx.vim
/var/lib/nginx
/var/lib/nginx/tmp
/var/log/nginx

而後咱們就找到配置文件的路徑/etc/nginx/nginx.conf。
