actually borrows the name of the Libeventstruct event, because each instance of the event class corresponds to an object of Libeventevent. The focus we need to focus on is Procedure and the Client class.
Procedure class
There are two key features of the Procedure class:
Each object has a LIBCO, which has its own independent contextual information that can be used to write a separate server process (procedure);
It is necessary to write concurrent service-side programs while doing network service. The stability of the front-end client application is partly dependent on the client itself, and more depends on whether the server is fast enough and stable enough. The common Linux concurrent Server model;
Multi-Process Concurrent server
Multi-threaded Concurrent server
Select multi-channel I/O transfer server
process of disaster recovery, in simple terms, is the following steps:
Clone all virtual servers in area A, and revert to the ESX server in area B.
Open firewall port to ensure the connectivity between servers.
Sets the application portion of the server.
The first two steps are fixed routines that can be done according to standard practice.
The phpcurl function can be used to download files. the following example uses phpcurl to download files to process files manually synchronized between servers. if you are interested, go to the page. one requirement is as follows: two servers, one test server [apa... the php curl function can be used to download files. the following example uses php curl to downl
In the face of DHCP services and other related content, we not only understand some basic information about it, but also introduce some configuration and troubleshooting content. Next, we will mainly explain the troubleshooting process of DHCP servers based on the interface address pool. We have introduced its network environment and processing process.
DHCP ser
must find a port that can be accessed externally. However, the firewall does not allow external access to all ports. After some tests, we found that all ports allowed to access are occupied. Look at the process carefully and find that chatserver occupies 4 ports, each of which corresponds to a chat room, and no one is using these chat rooms. So I will kill one of the processes first, so that a shell can be bound to the corresponding port.

Because the company has two Windows servers, development in the operation of the general is to upload some data on these two servers or modify something, and Linux server on the windows to be consistent with the data and do not need to implement this process, based on this process, yesterday took a little time, Complet
Linux vsftp servers must be refined throughout the entire process-Linux Enterprise applications-Linux server application information. The following is a detailed description. 1. First, check whether rpm qa | grep vsftpd is installed.
If not, download the ftp://vsftpd.beasts.org/users/cevans/ here
2. Let's download the latest version 2.01 and put it under ftp://vsftpd.beasts.org/users/cevans/
3. Then we need

So far, our servers have no practical use. Next we will start to implement some practical and useful functions.
What we need to do is: select a file, upload the file, and view the uploaded file in the browser.
First, we need a processing area (textarea) for the user to input the content, and the
Nethogs is an open source network traffic monitoring tool that shows the bandwidth usage of each process, which makes it more intuitive to use the network. Nethogs supports IPV4 and IPV6 protocols, supports local network cards, and PPP links.Where the PID column shows the program's process number, the user column shows the program's owner, the program column shows the specific name of the programs, the Dev

After the https load balancer is started, if an instance fails to register, the server intranet IP, port, firewall, SELinux, security Group Policy, The status of the Apache server to troubleshoot the problem (pay attention to the addition of port 443 for HTTPS) or refer to the official troubleshooting document. If the account does not have administrator rights after the audit starts, please contact the administrator to obtain the appropriate permissions. finally use El
