五、部署 Nginx 1.4.3 实现负载均衡   用Nginx做为负载均衡器,配置简单。而且通过Nginx访问到无响应的主机时,Nginx会自动将客户的请转到另一台主机,而无需客户重新提交请求。因此对于客户来讲,只要Nginx指向的主机中有一台有响应,客户就能访问到相应的数据。   1、安装 nginx 1.4.3 [root@nginx 桌面]# rpm -ivh nginx-1.4.3-1.e16.ngx.x86_64.rpm warning nginx-1.4.3-1.el6.ngx.x86_64.rpm:Header V4 RSA/SHA1 Signature, key ID 7bd9bf62: NOKEY Preparing... #####################################[100%] 1:nginx #####################################[100%] ------------------------------------------------------------ Thanks for using nginx! Please find the official documentation for nginx here: * http://nginx.org/en/docs/ Commercial subscriptions for nginx are available on: * http://nginx.com/products/ ------------------------------------------------------------   2、修改配置文件 /etc/nginx/conf.d/default.conf 使得来自 80 端口的请求转发到5台solr主机的 80 端口(即项目的网址),来自 9888 端口的请求转发至5台solr主机的9888端口(即SolrCloud的网址) [root@nginx 桌面]# vi /etc/nginx/conf.d/default.conf upstream SolrCloud{ server solr1.jyga.com:9998 max_fails=3 fail_timeout=5h; server solr2.jyga.com:9998 max_fails=3 fail_timeout=5h; server solr3.jyga.com:9998 max_fails=3 fail_timeout=5h; server solr4.jyga.com:9998 max_fails=3 fail_timeout=5h; server solr5.jyga.com:9998 max_fails=3 fail_timeout=5h; } upstream JYGA{ server solr1.jyga.com:80 max_fails=3 fail_timeout=5h; server solr2.jyga.com:80 max_fails=3 fail_timeout=5h; server solr3.jyga.com:80 max_fails=3 fail_timeout=5h; server solr4.jyga.com:80 max_fails=3 fail_timeout=5h; server solr5.jyga.com:80 max_fails=3 fail_timeout=5h; } server { listen 9998; server_name localhost; #access_log /var/log/nginx/log/host.access.log main; location / { root /usr/share/nginx/html; index index.html index.htm; proxy_pass http://SolrCloud; } #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 /usr/share/nginx/html; } } server { listen 80; server_name localhost; #access_log /var/log/nginx/log/host.access.log main; location / { root /usr/share/nginx/html; index index.html index.htm; proxy_pass http://JYGA; } #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 /usr/share/nginx/html; } }   3、启动 nginx[root@nginx 桌面]# nginx   4、访问项目和SolrCloud的网址     http://nginx.jyga.com/jyga         #项目的网址,实际是哪台服务器在提示Web服务,不得而知     http://nginx.jyga.com:9998/solr    #SolrCloud的访问网址
