例外：bus.Bus 不可用 - Odoo 10

Question

目前我在不同的机器上有两个不同的数据库，它们显示以下错误。第一次出现是几个月前，偶尔出现在日志中，有时连续多次出现，有时一天只出现一次。

只有在 proxy_mode = True 和/或工作人员数量 > 0 的情况下运行 Odoo 时才会发生这种情况。禁用代理后，错误就会停止。

Traceback (most recent call last):
  File "/odoo/odoo-server/odoo/http.py", line 638, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)
  File "/odoo/odoo-server/odoo/http.py", line 675, in dispatch
    result = self._call_function(**self.params)

这是我当前的 Nginx 配置：

upstream odoo10 {
    server myipaddres:8069 weight=1 fail_timeout=0;
}

upstream odoo10-im {
    server myipaddres:8072 weight=1 fail_timeout=0;
}

## http redirects to https ##
server {
    listen 80;
    server_name mydomain.com;

    # Strict Transport Security
    add_header Strict-Transport-Security max-age=2592000;

    rewrite ^/.*$ https://$host$request_uri? permanent;
}

server {
    # server port and name
    listen 443 ssl;
    server_name mydomain.com;

    # Specifies the maximum accepted body size of a client request,
    # as indicated by the request header Content-Length.
    client_max_body_size 200m;

    # add ssl specific settings
    keepalive_timeout 60;
    ssl on;
    ssl_certificate /etc/ssl/nginx/mydomain.crt;
    ssl_certificate_key /etc/ssl/nginx/mydomain.key;

    # limit ciphers
    ssl_ciphers HIGH:!ADH:!MD5;
    ssl_protocols SSLv3 TLSv1;
    ssl_prefer_server_ciphers on;

    # increase proxy buffer to handle some OpenERP web requests 
    proxy_buffers 16 64k;
    proxy_buffer_size 128k;

    #general proxy settings
    # force timeouts if the backend dies
    proxy_connect_timeout 600s;
    proxy_send_timeout 600s;
    proxy_read_timeout 600s;

    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;

    # set headers
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;

    # Let the OpenERP web service know that we’re using HTTPS, otherwise
    # it will generate URL using http:// and not https://
    proxy_set_header X-Forwarded-Proto https;

    # by default, do not forward anything
    proxy_redirect off;
    proxy_buffering off;

    location / {
        proxy_pass http://odoo10;
    }

    location /longpolling {
        proxy_pass http://odoo10-im;
    }

    # cache some static data in memory for 60mins.
    # under heavy load this should relieve stress on the OpenERP web interface a bit.

    location /web/static/ {
        proxy_cache_valid 200 60m;
        proxy_buffering on;
        expires 864000;
        proxy_pass http://odoo10;
    }

}

以及 etc/odoo-conf 中与性能相关的部分：

[options] 
# ...
db_maxconn = 64  
limit_memory_hard = 2684354560 
limit_memory_soft = 2147483648 
limit_request = 8192 
limit_time_cpu = 600 limit_time_real = 1200 limit_time_real_cron = 2400
max_cron_threads = 2 
osv_memory_age_limit = 1.0 
osv_memory_count_limit = False 
proxy_mode = True 
workers = 5 xmlrpc = True 
xmlrpc_interface = myipaddress 
netrpc_interface = myipaddress
# ...

这目前在 Digital Ocean 基础设施上运行，在具有 2GB RAM 和 2 个 CPU 内核的机器上。

Answer 1

在您的 nginx.conf 文件中，添加以下行：

location /longpolling {
proxy_pass http://127.0.0.1:8072;
}
location / {
    proxy_pass http://127.0.0.1:8069;
}

Answer 2

你需要很多行

最新文档：https://www.odoo.com/documentation/12.0/setup/deploy.html#https

一些值得注意的 odoo.conf 设置，db maxconn 可能会导致 postgres 出现问题，并且假设至少有一个 8GB RAM 四核服务器，请在此处查看详细信息：https://gist.github.com/Guidoom/d5db0a76ce669b139271a528a8a2a27f

db_maxconn = 256
proxy_mode = True
limit_memory_hard = 1395864371
limit_memory_soft = 572662306
limit_request = 8192
limit_time_cpu = 1800
limit_time_real = 1800
workers = 9

这是一个有效的 nginx 配置，代理超时和上游的东西似乎也很重要。但是，代理缓冲区值得商榷：https://stackoverflow.com/a/50891625/1689770

不要复制 certbot 的东西，它是由 certbot 自动生成的，我只是把它留在那里以供上下文参考

    keepalive_timeout   600;

    # Redirect longpoll requests to odoo longpolling port
    location /longpolling {
