是在是中不到JDK7在哪里下载，yum源里都是openjdk

http://download.csdn.net/download/love254443233/9179483

于是就在本地下载了，然后传服务器上,没有端口限制，如果有就 -P port

scp  ./Desktop/jdk-7u79-linux-x64.tar.gz  root@120.27.217.101:/root
jdk-7u79-linux-x64.tar.gz                                                                             100%  146MB   3.7MB/s   00:40

• 解压 tar -zxvf jdk-7u75-linux-x64.tar.gz
• 配置java环境 ~/.bas_profile

• 配置java环境变量就不讲了，直接

[root@izbp1gtcdnye16djqbbqjdz ~]# ls
jdk1.7.0_79  jdk-7u79-linux-x64.tar.gz
[root@izbp1gtcdnye16djqbbqjdz ~]# vi /etc/profile

(1)使用yum安装nginx需要包括Nginx的库，安装Nginx的库

rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

(2)使用下面命令安装nginx

yum install nginx

(3)启动Nginx

systemctl status nginx.service

用systemctl restart nginx.service重启

(4) cat /etc/nginx/nginx.conf 配置地址

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;


    server {
        listen       80;
        server_name  127.0.0.1:8080;

        location / {

            proxy_pass   http://127.0.0.1:8080;
        }

    }

}

server下的结点：

listen：监听80端口

server_name：转发到哪个地址

proxy_pass：代理到哪个地址

nginx常用命令（要进入到nginx的目录）：

开启：start nginx

重启：nginx -s reload
