. As we all know,linux system everything is a file, so each process has its file descriptor, The Nginx process writes its own file descriptor to the Nginx.pid, and we need to tell Nginx to reopen a new log file (the configuration details of the log file can be seen here, simply by letting the log record what. So we need this directive:kill -USR1 `cat ${pid_path}`This instruction means: first cat to Nginx PID, is an integer, and then send the signal

Suse Linux DHCP configuration file The first step in configuring the DHCP server is to create a configuration file for storing the customer's network information. Global options can be declared for all customers, and optional options can be declared for each customer system. This configuration file can be simply formatted using any additional tab or blank lines. The keyword i

DHCP is a Dynamic Host Configuration protocol. This protocol is used to automatically provide computers with IP addresses, subnet masks, and routing information. Network administrators typically allocate a range of IP addresses to clients on the local area network. When the device is connected to the local area network, they request an IP address from the DHCP server. The DHCP server then assigns an address to each requested device until all IP addresses within that range are assigned. The assig

Add a broadcast routeIn this actual working environment, machines in the LAN are connected to the eth1 Nic of the Linux server through a switch. To broadcast the entire LAN on a Linux server, add the following route: #route add -host 255.255.255.255 -dev eth1 Add the preceding route to/etc/rc.
