阿里雲Centos伺服器安裝Nginx

• 安裝依賴

  yum install openssl
  ​
  yum install zlib
  ​
  yum install pcre
  ​
  rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

• 安裝Nginx

  yum install nginx

• 啟動Nginx/重啟Nginx

  service nginx start  # 啟動
  service nginx restart  # 重啟

• 驗證安裝

  在安全組設定中，開放伺服器80埠。
  瀏覽器訪問http://{伺服器ip}，出現歡迎介面表示安裝且啟動成功。

  # 配置檔案路徑
  /etc/nginx/nginx.conf
  # 上面的檔案預設會引用/etc/nginx/conf.d資料夾下的所有結尾為.conf的配置檔案，其中該資料夾預設存在一個default.conf配置檔案。

• 簡單使用

  • 轉發

    server {
        listen       80;
        server_name  localhost;
    ​
        #access_log  /var/log/nginx/host.access.log  main;
    ​
        location / {
            # root   /usr/share/nginx/html;
            # index  index.html index.htm;
            proxy_pass http://127.0.0.1:5000;  # 將服務端80埠接收的請求轉發到127.0.0.1:5000
        }
    ​
        #error_page  404              /404.html;

        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    ​
        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {

        #
        #location ~ \.php$ {

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

  • 負載均衡

    upstream myserver {
            ip_hash;  # 負載均衡演算法，有多種可選，可以選擇多種均衡策略
            server 127.0.0.1:5000;
            server 127.0.0.1:5001;
            server 127.0.0.1:5002;
        }
    ​
    ​
    server {

        #access_log  /var/log/nginx/host.access.log  main;
    ​
        location / {
            proxy_pass http://myserver;  # 將伺服器80埠接收的請求轉發到負載均衡組myserver中
