1.安装说明：
系统环境：Ubuntu 14.04.3 LTS
软件：nginx-1.8.0.tar.gz
安装位置：/opt/nginx
2.安装
需要用到的安装包：
openssl-fips-2.0.10.tar.gz
zlib-1.2.8.tar.gz
pcre-8.37.tar.gz
nginx-1.8.0.tar.gz
安装顺序依次为:openssl、zlib、pcre, 然后安装Nginx包
2.1安装openssl-fips-2.0.2.tar.gz
tar –zxvf openssl-fips-2.0.10.tar.gz
cd openssl-fips-2.0.10
./config
make
make install
2.2 安装zlib-1.2.8.tar.gz
tar –zxvf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure
make
make install
2.3安装pcre-8.37.tar.gz (需安装编译c++环境: apt-get install build-essential)
在安装pcre-8.37.tar.gz之前需要安装c++编译环境，否则在执行./configure时会报错。
apt-get install build-essential
tar –zxvf pcre-8.37.tar.gz
cd pcre-8.37
./configure
make
make install
2.4安装nginx-1.8.0.tar.gz
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --with-pcre=../pcre-8.37 --with-zlib=../zlib-1.2.8 --with-openssl=../openssl-fips-2.0.10
make
make install
至此Nginx的安装完成!
检测nginx是否安装成功
cd /usr/local/nginx/sbin
./nginx –t
出现如下所示提示,表示安装成功
root@wcyong :/usr/local/nginx/sbin# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
启动nginx
./ngixn
查看端口：
netstat -tnlp | grep nginx
root@wcyong :/usr/local/nginx/sbin# netstat -tnlp | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 2957/nginx
并且通过浏览器访问
3.nginx负载均衡配置
打开 /usr/local/nginx/conf/nginx.conf 配置文件，做如下配置即可：
user root root;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
error_log logs/error.log warn;
pid logs/nginx.pid;
events {
worker_connections 1024;
}

default_type application/octet-stream;
