nginx

环境

centerOS 7

yum -y install gcc gcc-c++ make libtool zlib zlib-devel openssl openssl-devel pcre pcre-devel

./configure –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module –with-http_realip_module

make && make install

测试 /usr/local/nginx/sbin/nginx

---

例：./configure –prefix=/usr/local/nginx-1.6 –with-pcre \
–with-http_stub_status_module –with-http_ssl_module \
–with-http_gzip_static_module –with-http_realip_module \
–add-module=../nginx_upstream_check_module-0.3.0
nginx大部分常用模块，编译时./configure –help以–without开头的都默认安装。
–prefix=PATH ： 指定nginx的安装目录。默认 /usr/local/nginx
–conf-path=PATH ： 设置nginx.conf配置文件的路径。nginx允许使用不同的配置文件启动，通过命令行中的-c选项。默认为prefix/conf/nginx.conf
–user=name： 设置nginx工作进程的用户。安装完成后，可以随时在nginx.conf配置文件更改user指令。默认的用户名是nobody。–group=name类似
–with-pcre ： 设置PCRE库的源码路径，如果已通过yum方式安装，使用–with-pcre自动找到库文件。使用–with-pcre=PATH时，需要从PCRE网站下载pcre库的源码（版本4.4 – 8.30）并解压，剩下的就交给Nginx的./configure和make来完成。perl正则表达式使用在location指令和 ngx_http_rewrite_module模块中。
–with-zlib=PATH ： 指定 zlib（版本1.1.3 – 1.2.5）的源码解压目录。在默认就启用的网络传输压缩模块ngx_http_gzip_module时需要使用zlib 。
–with-http_ssl_module ： 使用https协议模块。默认情况下，该模块没有被构建。前提是openssl与openssl-devel已安装
–with-http_stub_status_module ： 用来监控 Nginx 的当前状态
–with-http_realip_module ： 通过这个模块允许我们改变客户端请求头中客户端IP地址值(例如X-Real-IP 或 X-Forwarded-For)，意义在于能够使得后台服务器记录原始客户端的IP地址
–add-module=PATH ： 添加第三方外部模块，如nginx-sticky-module-ng或缓存模块。每次添加新的模块都要重新编译（Tengine可以在新加入module时无需重新编译）

}`

在conf目录创建 vhosts目录
增加节点配置文件如
`server {
listen 80;
server_name i.image.com;
access_log /var/log/nginx/access.log ;
error_log /var/log/nginx/error.log;

    proxy_connect_timeout 300;
    proxy_read_timeout 300;
    proxy_send_timeout 300;
    proxy_buffer_size 64k;
    proxy_buffers 4 64k;
    proxy_busy_buffers_size 128k;


    location / {
            root /data;
            expires 7d;
    }

    #location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ { 
    #root /data/static;
    #       expires      7d; 
    #}

}`

或
upstream web{
server 127.0.0.1:10004;
#server ;
}

server {
listen 80;
server_name www.xx.com;
access_log /var/log/nginx/access.log ;

            proxy_pass http://web;
            break;

/usr/local/nginx/sbin/nginx -t 检查

/usr/local/nginx/sbin/nginx -V 显示编译参数

./sbin/nginx -s stop 或 pkill nginx

重启，不会改变启动时指定的配置文件

./sbin/nginx -s reload

或 kill -HUP cat /usr/local/nginx-1.6/logs/nginx.pid
