环境准备

ip                 主机名                        端口
192.168.148.130    Nginx                         80
192.168.148.131    Tomcat-node1                  8080
192.168.148.132    Tomcat-node2                  8080

关闭iptables防火墙和selinux。如果是生产环境，开启iptables后，需要开放对应的应用端口，每台机器同样执行。

[root@Nginx ~]# setenforce 0
[root@Nginx ~]# getenforce
disabled
[root@Nginx ~]# cat /etc/sysconfig/selinux |grep "SELINUX=disabled"
SELINUX=disabled
[root@Nginx ~]# /etc/init.d/iptables stop

安装Nginx

[root@Nginx ~]# cd /usr/local/src/
[root@Nginx src]# ll
[root@nginx ~]# wget http://nginx.org/download/nginx-1.8.1.tar.gz 
[root@nginx ~]# tar  xvf nginx-1.8.1.tar.gz
[root@nginx ~]# cd nginx-1.8.1
[root@nginx nginx-1.8.1]# ./configure  --prefix=/usr/local/nginx  --sbin-path=/usr/local/nginx/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --error-log-path=/var/log/nginx/error.log  --http-log-path=/var/log/nginx/access.log  --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock  --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre  && make && make install
安装成功后配置nginx
[root@Nginx  nginx-1.8.1]# cd /usr/local/nginx/conf/
[root@Nginx conf]# cp nginx.conf nginx.conf.bak
