Nginx (Web server)

Loading

工作平台為 CentOS 7.2 最小安裝. Nginx (音同 Engine X ,Web ,HTTP 伺服器)

YUM 預設並沒有 Nginx (Web server),所以我們需要手動的新增 Nginx 的 Repo 檔 ,手動編寫 /etc/yum.repos.d/nginx.repo 或是直接安裝 nginx 提供的 Repo 設定套件.

[root@localhost ~]# yum install nginx
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: centos.cs.nctu.edu.tw
 * extras: centos.cs.nctu.edu.tw
 * updates: centos.cs.nctu.edu.tw
No package nginx available.
Error: Nothing to do
[root@localhost ~]# rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

這樣就會在 /etc/yum.repos.d/ 目錄產生 nginx.repo 檔案

 
[root@localhost ~]# cat /etc/yum.repos.d/nginx.repo 
# nginx.repo

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

接下來就可以安裝 nginx 了.

[root@localhost ~]# yum install nginx                                              

這樣就結束了,確認一下 nginx 是否開啟 #systemctl start , 開機是否啟動 #systemctl enable

[root@localhost ~]# systemctl start nginx.service
[root@localhost ~]# systemctl status nginx
● nginx.service - nginx - high performance web server
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)

           ├─28772 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx....
           └─28773 nginx: worker process

確認 nginx.service; 狀態為 enabled

[root@localhost ~]# systemctl enable nginx.service

透過瀏覽器來檢查一下,如果可以看到如下的畫面即代表 nginx 服務已經正常啟動.
nginx01

nginx 的設定檔 /etc/nginx/nginx.conf 與 /etc/nginx/conf.d/default.conf ,這邊有定義了他的 http Root (網站內容的根目錄) 為 /usr/share/nginx/html (與 Apache 的 Document Root – /var/www/html 不相同) , 預設已經有 index.html (就是剛剛看到的 HTML)

[root@localhost html]# cat /etc/nginx/conf.d/default.conf
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}

不過現在 nginx 還不認識 PHP ,這時候開啟關於 PHP 檔案 Nginx 會把它當作一般檔案來下載,我們還需要設定 PHP-FPM – https://benjr.tw/95767
