nginx_安装测试

shaozhiqi 2018-04-03 15:13 原文

 

首先安装环境： 

[root@local nginx-1.9.14]#  yum install gcc-c++  pcre pcre-devel  zlib zlib-devel openssl openssl--devel –y

安装之前，最好检查一下是否已经安装有nginx

 $   find -name nginx

如果系统已经安装了nginx，那么就先卸载

$   yum remove nginx 
$   cd /usr/local

从官网下载最新版的nginx

  $   wget http://nginx.org/download/nginx-1.7.4.tar.gz // wget     http://nginx.org/download/nginx-1.8.1.tar.gz

　　

解压nginx压缩包

   $   tar -zxvf nginx-1.7.4.tar.gz

会产生一个nginx-1.7.4 目录，这时进入nginx-1.7.4目录

$   cd  nginx-1.7.4

接下来安装，使用--prefix参数指定nginx安装的目录,make、make install安装

 $  ./configure --prefix=/usr/local/nginx            //默认安装在/usr/local/nginx  
 $   make 
 $   make install

启动nginx# /usr/local/nginx/sbin/nginx

停止nginx# kill -QUIT `cat /usr/local/nginx/logs/nginx.pid`

重启nginxkill -HUP `cat /usr/local/nginx/logs/nginx.pid`

添加到自启动# echo "/usr/local/nginx/sbin/nginx">>/etc/rc.local

chmod a+x  /etc/rc.local    执行这个才能设置成功

如果没有报错，顺利完成后，最好看一下nginx的安装目录

 配置负载均衡

 

修改配置文件

 $   whereis nginx

　　

 

配置后台服务

upstream mysvr {   
        #weigth参数表示权值,权值越高被分配到的几率越大  
        server 16.158.51.206:8098 weight=5;   
        server 16.158.51.206:8097 weight=5;   
        #server 192.168.207.131:8080 weight=2; 

     }

　　

访问测试：

@Test
public void  testqueryCompAndOrders(){
    String url="http://16.158.51.2/wos/comp/sendDetail";
    Map map=new HashMap<String, String>();
    map.put("reqId","\'C4012016042214145900001\'");
    postHttpRequestParams(url, map.toString());
}

关闭防火墙

systemctl stop firewalld
设置开启不启动：systemctl disable  firewalld
