Nginx安装 http://www.linuxidc.com/Linux/2016-08/134110.htm
安装前的准备
1）准备 pcre-8.12.tar.gz。该文件为正则表达式库。让nginx支持rewrite需要安装这个库。
2) 准备 nginx-1.5.0.tar.gz。该文件为nginx的linux版本安装文件。
3）确保进行了安装了linux常用必备支持库。
1）确保进行了安装了linux常用必备支持库。检查是否安装了g++、gcc。rpm -qa | grep gcc 之后需要出现3个包如下图所示。如果没有出现。需要安装g++、gcc。
# yum install gcc-c++
2)解压pcre-8.12.tar.gz
# cd /usr/local/src/nginx
# tar zxvf pcre-8.12.tar.gz
cd pcre-8.12
./configure
make
make install
Nginx安装
0) 创建用户nginx使用的www用户。
# groupadd www #添加www组
# useradd -g www www -s /bin/false #创建nginx运行账户www并加入到www组，不允许www用户直接登录系统
a) 安装目录
# mkdir /usr/local/nginx
b) 日志目录
# mkdir /data0/logs/nginx
# chown www:www /data0/logs/nginx -R
1) 判断系统是否安装了zlib-devel。如果没有安装。使用
# yum install -y zlib-devel
2) 解压
# cd /usr/local/src/nginx
# tar zxvf nginx-1.5.0.tar.gz
3) 进入目录
# cd nginx-1.5.0
4) 配置。通常将软件安装在/usr/local/目录下。
# ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module
5）编译
# make
6) 安装
# make install
7) 检查是否安装成功
# cd /usr/local/nginx/sbin
# ./nginx -t
配置防火墙80端口
#修改防火墙配置：
# vi + /etc/sysconfig/iptables
#添加配置项
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
#重启防火墙
# service iptables restart
3.5 上传配置文件
1）上传nginx.conf （文件下载地址见上面的Linux公社资源站）
# cd /usr/local/nginx/conf
# rz nginx.conf
2) 上传fastcgi_params.phis
# rz fastcgi_params.phis
3.6 启动停止重启与测试
1）启动
#方法1
# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
#方法2
# cd /usr/local/nginx/sbin
# ./nginx
2) 停止
#查询nginx主进程号
ps -ef | grep nginx
#停止进程
kill -QUIT 主进程号
#快速停止
kill -TERM 主进程号
#强制停止
pkill -9 nginx
3) 重启(首次启动需：/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf)
/usr/local/nginx/sbin/nginx -s reload
4）测试
#测试端口
netstat -na | grep 80
#浏览器中测试
http://ip:80
******************************************************************简单模拟 http://blog.csdn.net/lishaojun0115/article/details/53200629
1、模拟n个http服务器作为目标主机
用作测试，简单的使用2个tomcat实例模拟两台http服务器，分别将tomcat的端口改为8081和8082
2、配置IP域名
192.168.72.49 8081.max.com
192.168.72.49 8082.max.com
3、配置nginx.conf
upstream tomcatserver1 {
server 192.168.72.49:8081;
}
upstream tomcatserver2 {
server 192.168.72.49:8082;
}
server {
listen 80;
server_name 8081.max.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_pass http://tomcatserver1;
index index.html index.htm;
}
}
server {
listen 80;
server_name 8082.max.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_pass http://tomcatserver2;
index index.html index.htm;
}
}
流程：
1）浏览器访问8081.max.com，通过本地host文件域名解析，找到192.168.72.49服务器（安装nginx）
2）nginx反向代理接受客户机请求，找到server_name为8081.max.com的server节点，根据proxy_pass对应的http路径，将请求转发到upstream tomcatserver1上，即端口号为8081的tomcat服务器。
4、效果展示
请求8081.max.com，tomcat1接收返回首页
请求8082.max.com，tomcat2接收返回首页
