nginx

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

[root@local html]# vi /usr/local/nginx/conf/nginx.conf

[root@local html]# cat /usr/local/nginx/conf/nginx.conf #user  nobody; worker_processes  2; error_log  logs/error.log; #error_log  logs/error.log  notice; #error_log  logs/error.log  info; pid        logs/nginx.pid; events {     worker_connections  10240; } http {     include       mime.types;     default_type  application/octet-stream;     #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '     #                  '$status $body_bytes_sent "$http_referer" '     #                  '"$http_user_agent" "$http_x_forwarded_for"';     #access_log  logs/access.log  main;     sendfile        on;     #tcp_nopush     on;     #keepalive_timeout  0;     keepalive_timeout  65;     #gzip  on;     upstream mysvr {         #weigth参数表示权值,权值越高被分配到的几率越大         server 16.158.51.206:80 weight=5;         server 16.158.51.51:80 weight=5;         #server 192.168.207.131:8080 weight=2;     }     server {         listen       80;         server_name  16.158.51.2;         index index.html;         root /data0/htdocs/www;         #charset koi8-r;         #access_log  logs/host.access.log  main;         # location / {         #     root   html;         #     index  index.html index.htm;         # }         #对 "/" 启用负载均衡         location / {         proxy_pass http://mysvr;  #以这种格式来使用后端的web服务器         proxy_redirect off;         proxy_set_header Host $host;         proxy_set_header X-Real-IP $remote_addr;         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;         client_max_body_size 10m;         client_body_buffer_size 128k;         proxy_connect_timeout 90;         proxy_send_timeout 90;         proxy_read_timeout 90;         proxy_buffer_size 4k;         proxy_buffers 4 32k;         proxy_busy_buffers_size 64k;         proxy_temp_file_write_size 64k;         }         #error_page  404              /404.html;         # redirect server error pages to the static page /50x.html         #         # error_page   500 502 503 504  /50x.html;         # location = /50x.html {             #    root   html;             #}         # proxy the PHP scripts to Apache listening on 127.0.0.1:80         #         #location ~ \.php$ {             #    proxy_pass   http://127.0.0.1;             #}         # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000         #         #location ~ \.php$ {             #    root           html;             #    fastcgi_pass   127.0.0.1:9000;             #    fastcgi_index  index.php;             #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;             #    include        fastcgi_params;             #}         # deny access to .htaccess files, if Apache's document root         # concurs with nginx's one         #         #location ~ /\.ht {             #    deny  all;             #}     }     # another virtual host using mix of IP-, name-, and port-based configuration     #     #server {         #    listen       8000;         #    listen       somename:8080;         #    server_name  somename  alias  another.alias;         #    location / {         #        root   html;         #        index  index.html index.htm;         #    }         #}     # HTTPS server     #     #server {         #    listen       443 ssl;         #    server_name  localhost;         #    ssl_certificate      cert.pem;         #    ssl_certificate_key  cert.key;         #    ssl_session_cache    shared:SSL:1m;         #    ssl_session_timeout  5m;         #    ssl_ciphers  HIGH:!aNULL:!MD5;         #    ssl_prefer_server_ciphers  on;         #    location / {         #        root   html;         #        index  index.html index.htm;         #    }         #} } [root@vincentdembp html]#

 

启动ngnix

[root@local html]# /usr/local/nginx/sbin/nginx

重启nginx

[root@local html]# /usr/local/nginx/sbin/nginx -s reload

 $   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
