Linux
清漆,隱藏埠號
我的設置如下:
**作業系統:**在 OpenVZ 虛擬機上執行的 CentOS 6.2。
Web 伺服器: Nginx 監聽 8080 埠
反向代理: varnish 監聽 80 埠
問題是 Varnish 將我的請求重定向到埠 8080,這會出現在地址欄中,像這樣
http://mysite.com:8080/directory/
,導致站點上的相關連結在請求中包含埠號 (8080),從而繞過 Varnish。該網站由 WordPress 提供支持。
如何允許 Varnish 使用 Nginx 作為埠 8080 上的後端而不將埠號附加到地址?
**編輯:**清漆設置如下:
我已經告訴 Varnish 守護程序預設監聽 80 埠。
VARNISH_VCL_CONF=/etc/varnish/default.vcl # # # Default address and port to bind to # # Blank address means all IPv4 and IPv6 interfaces, otherwise specify # # a host name, an IPv4 dotted quad, or an IPv6 address in brackets. # VARNISH_LISTEN_ADDRESS= VARNISH_LISTEN_PORT=80 # # # Telnet admin interface listen address and port VARNISH_ADMIN_LISTEN_ADDRESS=127.0.0.1 VARNISH_ADMIN_LISTEN_PORT=6082 # # # Shared secret file for admin interface VARNISH_SECRET_FILE=/etc/varnish/secret # # # The minimum number of worker threads to start VARNISH_MIN_THREADS=1 # # # The Maximum number of worker threads to start VARNISH_MAX_THREADS=1000 # # # Idle timeout for worker threads VARNISH_THREAD_TIMEOUT=120 # # # Cache file location VARNISH_STORAGE_FILE=/var/lib/varnish/varnish_storage.bin # # # Cache file size: in bytes, optionally using k / M / G / T suffix, # # or in percentage of available disk space using the % suffix. VARNISH_STORAGE_SIZE=1G # # # Backend storage specification VARNISH_STORAGE="file,${VARNISH_STORAGE_FILE},${VARNISH_STORAGE_SIZE}" # # # Default TTL used when the backend does not specify one VARNISH_TTL=120
Varnish 呼叫的 VCL 文件(通過 include in
default.vcl
)包括:backend playwithbits { .host = "127.0.0.1"; .port = "8080"; } acl purge { "127.0.0.1"; } sub vcl_recv { if (req.http.Host ~ "^(.*\.)?playwithbits\.com$") { set req.backend = playwithbits; set req.http.Host = regsub(req.http.Host, ":[0-9]+", ""); if (req.request == "PURGE") { if (!client.ip ~ purge) { error 405 "Not allowed."; } return(lookup); } if (req.url ~ "^/$") { unset req.http.cookie; } } } sub vcl_hit { if (req.http.Host ~ "^(.*\.)?playwithbits\.com$") { if (req.request == "PURGE") { set obj.ttl = 0s; error 200 "Purged."; } } } sub vcl_miss { if (req.http.Host ~ "^(.*\.)?playwithbits\.com$") { if (req.request == "PURGE") { error 404 "Not in cache."; } if (!(req.url ~ "wp-(login|admin)")) { unset req.http.cookie; } if (req.url ~ "^/[^?]+.(jpeg|jpg|png|gif|ico|js|css|txt|gz|zip|lzma|bz2|tgz|tbz|html|htm)(\?.|)$") { unset req.http.cookie; set req.url = regsub(req.url, "\?.$", ""); } if (req.url ~ "^/$") { unset req.http.cookie; } } } sub vcl_fetch { if (req.http.Host ~ "^(.*\.)?playwithbits\.com$") { if (req.url ~ "^/$") { unset beresp.http.set-cookie; } if (!(req.url ~ "wp-(login|admin)")) { unset beresp.http.set-cookie; } } }
所以我設法解決了這個問題,向任何試圖找到答案的人道歉,因為這不是我診斷的問題。
在我應用清漆之前,我告訴 wordpress 我的網站 url 是
playwithbits.com:8080
為了正確地提供內容,所以它將埠號附加到我的所有 URL 上。我完全忘記了這個設置,一旦我刪除了埠號,我的網站就開始正常工作了。
Varnish 本身從不發送 301 答案(除非你做了一些主要的 VCL 魔法),所以如果你得到一個重定向,它必須來自你的後端。
