A lotThe program you compile and install will automatically add/usr/local/lib to GCC's-l parameter at compile time, while running it automatically to/usr/local/lib under theFind a shared library.With these two types of dynamic shared libraries, applications will automatically find them and don't need your extra setup and worry. What is this for?

Original: routing configuration practices interconnection between two LAN hosts VM linux and vmlinux I believe that the network is essential for every O M personnel and developers. Today we want to talk about how to divide the three virtual machines in the vmvm into two local networks to implement different local networks. interconnection: the AC in the figure below communicates with each other through hos

When an slave server is connected to the master server, it notifies the master server of the last successful update location read from the server in the log. The slave server receives any updates from that time, blocks them, and waits for the master server to notify you of the next update. In the actual project, two hosts distributed in different regions are installed with MySQL databases, and the two servers are both active and standby. The customer

A stupid way to synchronize time between linux hosts in the LAN. in the past few days, a small cluster of eight nodes has been built in the lab using a obsolete pc to conduct an experiment on hama, from re-assembling the hardware to installing the system and configuring the cluster, after two days of busy working, it is full of gray. When installing a cluster, you often need to synchronize between nodes...

The difference between host name (Hostname) and domain name (domains)Hostname is the name of the machine itself, the domain name is used to resolve to the IP. But it is worth saying that in the local area network, the hostname can also be resolved to the IP, such as the example we said earlier;Display host Name:# HostnameRoot1The host name of this host is ROOT1, and no parameter is the hostname of the host that is us
