Package: nginx-extras
Version: 1.2.0-1
Severity: important
Tags: patch
I've been experiencing an issue with worker processes crashing when
using lua-resty-mysql (which uses cosocket) in an access_by_lua block,
returning with ngx.exit().
This issue has been reported here --
https://github.com/chaoslawful/lua-nginx-module/issues/110
and fixed here --
https://github.com/chaoslawful/lua-nginx-module/commit/d00976d807c64c50cd6e6d5895d17c95d9b1baef
I've confirmed that rebuilding the package with an updated
lua-nginx-module fixes this issue.
For reference, here's the config in question:
server {
listen 80;
error_page 401 403 /back-to-portal.html;
location = /back-to-portal.html {
internal;
root /usr/local/share/www;
}
location / {
access_by_lua '
local mysql = require "resty.mysql"
local db = mysql:new()
db:set_timeout(1000)
local ok, err, errno, sqlstate =
db:connect{
path = "/run/mysqld/mysqld.sock",
database = "testdb",
user = "testuser",
password = "password" }
ngx.exit(403)
';
}
}
