ps auxwww|grep -i 'server'should return all process which has serverin them. Otherwise, server may have already stopped.
ps auxwww|grep -i 'server'应该返回其中包含的所有进程server。否则，服务器可能已经停止。
You should be able to determine the PID (and store it in a file) as follows:
您应该能够确定 PID（并将其存储在文件中），如下所示：
nohup server &
print $! >> my_server.pid

The best way to launch a server in centos is with the service command.
在 centos 中启动服务器的最佳方式是使用 service 命令。
So
service httpd start
所以
service httpd start
There is a chance that you want to write your program as a daemon
您可能希望将程序编写为守护进程
A daemon (or service) is a background process that is designed to run autonomously,with little or not user intervention. The Apache web server http daemon (httpd) is one such example of a daemon. It waits in the background listening on specific ports, and serves up pages or processes scripts, based on the type of request.
守护进程（或服务）是一个后台进程，旨在自主运行，很少或不需要用户干预。Apache Web 服务器 http 守护程序 (httpd) 就是一个这样的守护程序示例。它在后台等待特定端口，并根据请求类型提供页面或处理脚本。

There is no definitive way to catch the exact process with the help of pscommand, but you can use the following:
在ps命令的帮助下没有确定的方法来捕获确切的过程，但您可以使用以下方法：
ps -a | grep "server"
You will get a list of all the processes running with the name "server"
您将获得所有以“服务器”名称运行的进程的列表
Or, you can use any other keywords as well to grep the ps output.
或者，您也可以使用任何其他关键字来 grep ps 输出。

If a nohup.out file was created, you may run in bash:
如果创建了 nohup.out 文件，您可以在 bash 中运行：
# lsof nohup.out
it will return the pid which created/is running the file
它将返回创建/正在运行文件的 pid
best regards!
此致！
