有沒有辦法在不實際使用新版本的情況下檢查清漆配置語法?
我正在尋找相當於本機清漆apache2ctl configtest
答案1
您可以要求 Varnish 將您的 VLC 檔案編譯為臨時檔案。這是我們腳本的一部分,它將新配置載入到我們的清漆伺服器:
tmpfile=$(mktemp)
trap 'rm -f $tmpfile' 0
varnishd -C -f /srv/web/fe/varnish/default.vcl > $tmpfile
echo
if [ ! -s $tmpfile ]; then
echo "ERROR: There are errors in the varnish configuration." >&2
exit 1
fi
這是可行的,因為如果 VCL 中存在錯誤,varnishd -C
則不會產生任何輸出。stdout
答案2
是關於什麼的varnish_reload_vcl
?
一些例子:
VCL 檔案沒有問題
$ varnish_reload_vcl Loading vcl from /etc/varnish/default.vcl Current running config name is reload_2016-01-28T15:18:23 Using new config name reload_2016-01-28T15:19:57 VCL compiled.

VCL 檔案中有錯誤
$ varnish_reload_vcl Loading vcl from /etc/varnish/default.vcl Current running config name is reload_2016-01-28T15:19:57 Using new config name reload_2016-01-28T15:21:51 Message from VCC-compiler: Symbol not found: 'b1' (expected type BACKEND): ('input' Line 77 Pos 32) set req.backend_hint = b1; -------------------------------##- Running VCC-compiler failed, exited with 2 VCL compilation failed Command failed with error code 106 varnishadm -S /etc/varnish/secret -T 127.0.0.1:6082 vcl.load failed
