nginx源码编译安装，第三方模块扩展，功能实现

实验环境

iptables和selinux关闭
redhat6.5
nginx:server2 172.25.254.2
服务器：
server1：172.25.254.1
server3：172.25.254.3

安装nginx

[root@server2 ~]# ls
nginx-1.14.0.tar.gz
[root@server2 ~]# tar zxf nginx-1.14.0.tar.gz
[root@server2 ~]# cd nginx-1.14.0/src/core
[root@server2 core]# vim nginx.h  //改变显示
#define NGINX_VER       "nginx"
[root@server2 core]# cd ..
[root@server2 src]# cd ..
[root@server2 nginx-1.14.0]# cd auto/cc
[root@server2 cc]# vim gcc  //注释
172 #CFLAGS="$CFLAGS -g"
[root@server2 cc]# ./configure --help
[root@server2 nginx-1.14.0]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-threads --with-file-aio  //检测编译环境是否完善
[root@server2 nginx-1.14.0]# make
[root@server2 nginx-1.14.0]# make install
[root@server2 nginx-1.14.0]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-threads --with-file-aio
[root@server2 nginx-1.14.0]# cd /usr/local/nginx/sbin/
[root@server2 sbin]# ln -s /usr/local/nginx/sbin/nginx /sbin/
[root@server2 sbin]# nginx -t   //检测语法错误
[root@server2 sbin]# nginx  //打开nginx
[root@server2 sbin]# nginx -s reload  //重新加载
[root@server2 sbin]# nginx -s stop  //关闭nginx
[root@server2 sbin]# cd ..
[root@server2 nginx]# cd html
[root@server2 html]# vim index.html

www.westos.org

[root@server2 html]# nginx

nginx做调度器 

[root@server2 ~]# cd /usr/local/nginx/conf
[root@server2 conf]# lscpu
CPU(s):                2
[root@server2 conf]# vim nginx.conf
user  nginx nginx;
worker_processes  2;
worker_cpu_affinity 01 10;
events {
    worker_connections  65535;
}
http {
        upstream ying {
#ip_hash;  //Ip不变后端服务器不变，持续的后端连接(默认为轮询)
        server 172.25.254.1:80;
        server 172.25.254.4:80;
        server 127.0.0.1;
        }
server{
                listen 80;
                server_name www.westos.org;  //域名访问
                location / {
                proxy_pass http://westos;  //调度westos
        }
        }
[root@server2 conf]# vim /etc/security/limits.conf
 nginx   -       nofile 65536
[root@server2 conf]# useradd -M -d /usr/local/nginx/ nginx
[root@server2 conf]# id nginx
uid=500(nginx) gid=500(nginx) groups=500(nginx)
[root@server2 conf]# nginx -t
[root@server2 conf]# nginx
[root@server2 conf]# nginx -s reload

打开服务器的httpd服务:
[root@server1 ~]# cat /var/www/html/index.html
www.westos.org -server1

[root@server4 ~]# cat /var/www/html/index.html
www.westos.org-server4

扩展模块

[root@server2 ~]# nginx -s stop
[root@server2 ~]# tar zxf nginx-1.10.1.tar.gz
[root@server2 ~]# tar zxf nginx-sticky-module-ng.tar.gz
[root@server2 ~]# cd nginx-1.10.1
[root@server2 nginx-1.10.1]# ./configure --prefix=/opt/nginx --with-http_ssl_module --with-http_stub_status_module --with-threads --with-file-aio --add-module=/root/nginx-sticky-module-ng//添加模块指定路径
[root@server2 nginx-1.10.1]# make
[root@server2 nginx-1.10.1]# make install
[root@server2 conf]# cd /opt/nginx/conf
[root@server2 conf]# cp /usr/local/nginx/conf/nginx.conf .
[root@server2 conf]# vim nginx.conf
http {
        upstream ying {
        sticky;  //上面14版本不支持本算法
        server 172.25.254.1:80;
        server 172.25.254.4:80;
        #server 127.0.0.1;
        }
[root@server2 conf]# /opt/nginx/sbin/nginx -t
[root@server2 conf]# /opt/nginx/sbin/nginx

虚拟主机的配置

[root@server2 conf]# vim nginx.conf
 server{
         listen 80;
         server_name www.westos.org;
         location / {
                 root /www1;
                 index index.html;
         }
 }
 server{
         listen 80;
         server_name www.linux.org;
         location / {
                 root /www2;
                 index index.html;
         }
 }

[root@server2 ~]# mkdir /www1
[root@server2 ~]# mkdir /www2
[root@server2 ~]# cd /www1
[root@server2 www1]# cat index.html
www.westos.org
[root@server2 www1]# cd
[root@server2 ~]# cd /www2
[root@server2 www2]# cat index.html
www.linux.org

 https加密
