First, configuration scenario: Due to machine aging, considering the reliability of the machine, decided to replace the server, because the old server is 3 network (telecommunications, Unicom, mobile), so on the new machine needs to configure 3 network connection 3 GatewaySecond, the configuration steps1. Configure the IP address on the three NICDescription: Use 192.168.1.x 192.168.2.x 192.168.3.x instead of 3 public network[Email protected] ~]# cat/etc/sysconfig/network-scripts/ifcfg-eth1device

default./usr/sbin/dhcpd3. This is the execution file for DHCP./etc/init.d/dhcp3-server. This is a service file that is used by DHCP to start or stop the service.The main function of profile/etc/default/dhcp3-server is to set up a network device and bind DHCP to a NIC. DHCP main configuration file/etc/dhcp3/dhcpd.conf is mainly for the server's various function parameters to set.Next, let's look at the configuration of the DHCP server: First we install Dhcp3-server, specific commands such as 1:F

Workaround: One, the problem may be the network card driver, network card and router compatibility is not good, and so on, we can update the Driver Wizard through the network card driver; Second, set the IP address of the advanced settings in the automatic access to the DHCP server, the system will give you the automatic gateway address; Third, try fixed IP address, DNS set into Google's 8.8.8.8 and 8.8.4.4, do not use the operator, there is confli

Win7 open Web page with browser three ways to 502 bad gateway errors Method One, shutdown agent 1, the first may be our browser using the agent, we open the desktop browser to find the right corner of the tool open, in the Drop-down menu to find the proxy server option; 2, then in the pop-up Proxy server option, choose not to use the proxy option in the front tick, and then restart the browser can be.

Method of solving Nginx 504 Gateway time-out Application is NGINX+TOMCAT7 According to this error, it is because Tomcat did not respond to nginx in time, resulting in errors. First use fiddler to grab the page's request. Find the 504 request. Then find out why. Because the request time is longer, only 90 seconds. So modify Proxy_connect_timeout 90; Proxy_send_timeout 90; Proxy_read_timeout 90; Modified into Proxy_connect_timeout 18000;

Server normal operation 2 months, the day before yesterday the whole station suddenly appeared 502 bad Gateway, all pages are not open, using the NGINX+PHP-FPM mode.Server situation: This server traffic is relatively large, PV around 300,000 per day, database use of MYSQL5, the largest table data has 800,000, the total database capacity of about 10G.The failure occurred immediately after the thought may be php-fpm hang off. PS to see the PHP-FPM proce

The way to resolve 502 Bad Gateway is: 1. Depending on the performance of the server, in the php-fmp.conf to increase the value of Max_children, I currently use 15. (a php-fpm uses about 20M of RAM, if your memory is about 1G,1024/20=50) 2. Use the reload parameter to reload the PHP-FPM periodically. Release the memory used by PHP-FPM, the PHP script execution time is too long to cause memory to use excessively, overload php-fpm can eliminate this

Virus Detection mechanism: a virus is a piece of code, and the final form is a file. Any data streams that are transmitted on the Internet must be composed of files to be detected by the anti-virus scanning engine. When browsing the Web page, we actually get a lot of html files, gif icons, and script files through the http protocol, and the files will eventually arrive at the user's place. To implement http virus filtering, the gateway anti-virus prod
