Nginx: worker_connections are not enough, reusing connections
We meet an error log on nginx: worker_connections are not enough, reusing connections
. To resolve this issue, here is my working solution according to the references:
Linux (pronounced Listeni/ˈlɪnəks/ lin-əks or, less frequently, /ˈlaɪnəks/ lyn-əks) is a Unix-like and mostly POSIX-compliant computer operating system (OS) assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on 5 October 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy.

It is becoming pretty slow in SSH to a CentOS server.
Trying to print a verbose log:

SSH Port Forwarding is a mechanism in SSH for tunneling application ports from the client machine to the server machine, or vice versa.
Suppose we wish to visit a port on a remote machine that is behind a firewall; we can use SSH port forwarding to bind that port to our local machine.
This post lists a few examples to check the status of your system in macOS and Linux
Here documents are indeed a powerful feature in Unix-like operating systems, allowing for the efficient creation and manipulation of files from within a shell script. They are particularly useful when you need to insert multiple lines of text into a file without having to resort to looping constructs or temporary files.
Changing the name of your os could be the first step after initialized you server -- at least it works for me. (more…)
一般情况下, 我们有很多工具可以安装字体, 即便在 linux 下, Gnome 等也提供了很多工具来这么做.
不过有时候会有些特殊需求. 比如我们要在某个远程服务器上添加一个字体.
有一些简单的方法可以处理. (more…)
效率上说和c++差不多,作为一个函数式程序,看起来也挺美观.官方的tutorial也做得很不错.目前为止,rust刷版本号已经刷到了1.1了,个人觉得可以试着做点东西了. (more…)
我们通常编辑 /etc/fstab
来确定启动时候挂载的硬盘, swap 等. 若文件内容有误, 重启后的效果就是直接挂了, 然后必须通过安全模式或者单用户模式进去修改, 这很麻烦.
可否不重启就检查下 fstab 呢? 答案是可以的. (more…)
