服务器可以打开多少个文件？
它是基于ram/cpu的吗？
/etc/security/limits.conf
* soft nproc 65536
* hard nproc 65536
* soft nofile 65536
* hard nofile 65536
root soft nproc 65536
root hard nproc 65536
root soft nofile 65536
root hard nofile 65536
我用它来增加限制，但我想知道这个数字是否65536可以更大？
另外，是否* sfot nproc也涵盖root soft nproc？还是需要为rootand指定*？
我最近运行了一个 sed 命令，但我输入了错误的命令（是的，确实发生了）。
所以现在我的目录和文件名看起来像'Call of Duty'. 如何递归返回并重命名所有文件和目录以删除'?
这是我运行的命令find . -type f -name "*.css" -exec sed -i'' -e 's|http://cdn|//cdn|g' {} +
我是 HAproxy 的新手，并且一直在遵循指南来帮助我入门。我想我得到了我需要的设置，但是当我尝试加载我的网站域时，我得到了一个

我不确定我在寻找什么，或者我可以从哪里开始寻找可能的问题。
我正在寻求帮助，可以为我指明正确的方向，甚至可以指出解决方案。
我一直试图找出为什么当我使用 ProFTPd 1.3.5b 上传全新的 wordpress 安装时，文件会被注入不属于文件的额外字符。
它只发生在/wp-includes/functions.php我所看到的
这些是我到目前为止打过的针

我通过端口 21 连接，常规 ftp（不是 sftp 或 tls）。也不使用被动模式。
我刚购买了一个 EV SSL，现在需要一些关于如何安装它的指导。
我遵循了 Geotrust 提供给我的步骤，但我无法弄清楚将我的代理服务器扔到哪里。
该域指向我的代理服务器，然后它很好地代理来自我的第二台服务器的内容。
在我的代理服务器中，我的 httpd.conf 中有这个
<VirtualHost *:80>
ProxyPreserveHost On
ProxyPass / http://xx.xx.xxx.xx:80/ connectiontimeout=300 timeout=300
ProxyPassReverse / http://xx.xx.xxx.xx:80/
</VirtualHost *:80>
在我的网络服务器中，我有
ServerName domain.com
ServerAlias www.domain.com
DocumentRoot "/var/www/html"
<Directory "/var/www/html">
AllowOverride All
Order allow,deny
Allow from all
</Directory>
我不知道在哪里插入这段代码
SSLEngine on
SSLCertificateFile /path/to/public_ee.crt
SSLCertificateKeyFile /path/to/private.key
SSLCertificateChainFile /path/to/EV_intermediate.crt
如果我将它添加到我的网络服务器，那么我会从代理收到“错误请求”错误，但我仍然可以通过以下方式访问该网址https
关于如何正确配置此类设置的任何线索？
谢谢您的帮助
