NGINX代理tomcat网站，tomcat挂掉三次了

royzs

上周的周四网站挂掉了，ps -ef查看tomcat进程都没了，这周周一网站挂了一次，还是用ps -ef查看tomcat进程消失了，周三又挂了一次，
我看nginx的错误日志只有以下内容

tomcat的catalina.out里面只有上千行的

1. 判断参数类型是栏目页面，还是内容页面
   
2. 判断参数类型是栏目页面，还是内容页面

在周一出问题之后，我在nginx.conf里面添加了

1. fastcgi_buffer_size 512k;
   
2. fastcgi_buffers 6 512k;
   
3. fastcgi_busy_buffers_size 512k;
   
4. fastcgi_temp_file_write_size 512k;

复制代码

并且修改了conf.d/www.conf中的内容成为

1. server {
   
2.         listen 80;
   
3.         server_name www.example.com
   
4.         if ($host != 'www.example.com' ) {
   
5.                 rewrite ^/(.*)$ http://www.example.com/$1 permanent;
   
6.         }
   
7. 
   
8.         location = / {
   
9.                 rewrite ^ /jeecms/index.jhtml break;
   
10.                 proxy_pass http://127.0.0.1:8080;
    
11.         }
    
12. 
    
13.         location / {
    
14.                 proxy_pass http://127.0.0.1:8080;
    
15.                 proxy_set_header Host $host;
    
16.                 proxy_set_header X-Real-IP $remote_addr;
    
17.                 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    
18. 
    
19.                 client_max_body_size         512m;
    
20.                 client_body_buffer_size      1024k;
    
21.                 proxy_connect_timeout        100;
    
22.                 proxy_send_timeout           100;
    
23.                 proxy_read_timeout           100;
    
24.                 fastcgi_read_timeout         180;
    
25.                 proxy_buffer_size            8k;
    
26.                 proxy_buffers                128 64k;
    
27.                 proxy_busy_buffers_size      128k;
    
28.                 proxy_temp_file_write_size   128k;
    
29.         }
    
30. }

复制代码

其中

1. 
   
2.                 client_max_body_size         512m;
   
3.                 client_body_buffer_size      1024k;
   
4.                 proxy_connect_timeout        100;
   
5.                 proxy_send_timeout           100;
   
6.                 proxy_read_timeout           100;
   
7.                 fastcgi_read_timeout         180;
   
8.                 proxy_buffer_size            8k;
   
9.                 proxy_buffers                128 64k;
   
10.                 proxy_busy_buffers_size      128k;
    
11.                 proxy_temp_file_write_size   128k;

是新增的内容
求助，我的配置有问题吗，这种情况该怎么解决呢

tomcat的bin目录下catalina.sh文件中添加有一行

1. JAVA_OPTS="-Xms1024m -Xmx1024m -Xss1024K -XX:PermSize=128m -XX:MaxPermSize=256m"

复制代码

设置tomcat启动参数，让它生成dump文件，然后分析dump文件。参考：
