无法启动 lighttpd 服务守护进程

Question

我想在我的远程 ubuntu 服务器上设置 lighttpd 并启动 flask 应用程序，但是当我使用 systemctl restart lighttpd

时遇到了一些麻烦

这是错误日志：

systemctl status lighttpd

这是我的 lighttpd.conf

cat /etc/lighttpd/lighttpd.conf

server.modules = (
        "mod_access",
        "mod_alias",
        "mod_compress",
        "mod_redirect",
        "mod_rewrite",
        "mod_fastcgi",
)

server.document-root        = "/var/www/"
server.upload-dirs          = ( "/var/cache/lighttpd/uploads" )
server.errorlog             = "/var/log/lighttpd/error.log"
server.pid-file             = "/var/run/lighttpd.pid"
server.username             = "www-data"
server.groupname            = "www-data"
server.port                 = 80

index-file.names            = ( "index.php", "index.html", "index.lighttpd.html" )
url.access-deny             = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )

compress.cache-dir          = "/var/cache/lighttpd/compress/"
compress.filetype           = ( "application/javascript", "text/css", "text/html", "text/plain" )

include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"

fastcgi.server = (
    "/" =>
    ((
        "socket" => "/tmp/landing-fcgi.sock",
        "bin-path" => "/var/www/landing/landing.fcgi",
        "check-local" => "disable",
        "max-procs" => 1
    ))
)

alias.url = (
    "/static/" => "/var/www/landing/static/",
)

url.rewrite-once = (
    "^(/static($|/.*))$" => "",
    "^(/.*)$" => "/landing.fcgi"
)

还有我的landing.fcgi

from flup.server.fcgi import WSGISerever
import app

if __name__ == '__main__':
    WSGIServer(app, bindAddress='/tmp/landing-fcgi.sock').run()

Answer 1

解决方案： 我发现非常好 python script 可以为 Flask 应用程序生成框架并创建基本的 lighttpd 配置。

它对我来说非常好，只是我与 flup 库发生冲突。

我安装了flup==1.0.3.dev-20110405版本并将python3解释器更改为python2解释器在我的 *.fcgi 文件中。

还有一件事我想说的是我删除了 118 字符串：

input("Press enter to continue (if everything is okay)...") 因为某些原因我遇到了异常。

希望我的回答对大家有所帮助。

Answer 2

lighttpd 可以执行 fastcgi 和 uwsgi（以及其他协议）。

flask 可以做 fastcgi 和 uwsgi，以及其他协议。

如果您使用 Flask 作为 WSGI 服务器，那么您应该使用 mod_scgi（而不是 mod_fastcgi）并使用 scgi.protocol = "uwsgi"[=12= 配置 mod_scgi ]
