It is well known that the replication of MySQL5.1 is rather rotten. Each version of MySQL updates about sync every time you see a whole bunch of them. But the MySQL 5.1 performance is more outstanding. So you can't resist using MySQL 5.1. So you also have to meet a few bugs frequently. Such as: Copy Code code as follows: Mysql> Show Slave Status\g 1. Row *************************** Slave_io_state:waiting for Master to send event master_host:192.168.10.118 Master_user:repl_wu mast

Today in the MySQL data directory of the local found many similar hostname-relay-bin.0000* files, the file is generally in the MySQL slave instance exists. The main purpose is to record the information of master-slave synchronization, which will normally be deleted automatically. This machine is not configured with Master, slave, and the source is really not clear. Since it is used on the slave, it can be relieved to delete. Delete the log file on th

section, the phenomenon has not changed, and Relay_log_file always on the same file.In order to find the cause of this phenomenon, we use strace to analyze. Because of the server phenomenon is very large disk write operations, so first use iotop to locate write a large number of thread ID, and then through the strace-p to analyze.The information collected through Strace is as follows:Read -,"376bin>303275t1721325322bg000k0000040005.5.31-"...,8192) = MaxLseek ( $,0, seekset) =0Write( $,"./

In wireless networking, we can simply divide it into two aspects from the user's perspective: home wireless networking and enterprise wireless networking. In enterprise networking, due to the wide network coverage and complicated structure, different Wireless AP network modes will be selected. Next we will introduce the wireless relay mode. The wireless relay mode, as its name implies, is the function of a

The complexity of the network structure also makes it difficult for us to maintain some of its services. Sometimes, some faults may inevitably occur. Here we will mainly explain the problem that the client in the DHCP relay fault cannot obtain the IP address of the same network segment as the IP address through the relay proxy. DHCP relay troubleshooting ◆ Networ

This section lets us learn the next Frame RelayFrame Relay in CCNA's exams and daily work are seldom useful, but we still want to know, it is after all a CCNA in the focus.Frame Relay (Frames relay)Also referred to as FRFrame Relay is an important WAN technology, its main function is to connect two or more long-distanc

Lab environment: 1. the topology is simple, but classic. The experiment is completed using the GNS simulator. 2. Four 36XX routers, one of which is configured as FR-SW. The router is directly connected to the frame relay switch. Lab requirements: 1. configure a vro as a frame relay switch 2. The other three routers are directly connected to the frame relay switch

Frame Relay is becoming increasingly popular today, but it has been widely used in past designs. This blog post briefly summarizes some concepts of FR from the second layer. Before introducing frame relay, let's first understand the differences between broadcast media and non-broadcast media: Broadcast media): Ethernet, token-ring, FDDI Features: The source can call all connected (L

A frame relay switch is a useful device, either in the lab or elsewhere. Like the boot register, the setting of the frame relay switch is also very profound in the router settings. You can build many different network models by learning how to configure a frame relay switch. As we are a "service provider", we must be able to independently allocate the full-induce

DHCP relay principle 1 When the dhcp client starts and initializes dhcp, it broadcasts the configuration request packets on the local network. 2. If the local network has a dhcp server, you can directly configure dhcp without the need for dhcp relay. 3. If the local network does not have a dhcp server, the network settings with the dhcprelay function connected to the local networkAfter receiving the broadca

Relay Knowledge:Relays have three terminals: normally open (NO), normally closed (NC), Grounded (C)If the connection takes a long time and occasionally requires a power outage, then NC and C are connected so that the relay set on is powered off. In addition, the relays can also control the keys, as well as the long press.The relay lights up when the

The smooth and fast sending and receiving of mails is the most basic and important function of the mail system. The unsatisfactory sending and receiving of mails seriously affects users' work efficiency and whether mail can be ensured, is the basic condition for determining whether a mail system is available. The turbogate email gateway system uses the Advanced Relay function for international mail sending and receiving. It supports multiple

Label:This document summarizes the definitions and explanations of the relevant parameters, which are generated by the relay log in the directory under the configuration file in the main master or master copy of MySQL. 1.

Frame Relay WAN Protocol Configuration 1. Frame Relay is a high-performance WAN protocol, which runs on the physical layer and data link layer of the OSI reference model. It is a data packet exchange technology and a simplified version of X.25. It skips some strong functions of X.25, such as window technology and data re-transmission technology, but relies on high-level protocols to provide error correction

Profile This article describes how to configure a remote domain for the Internet Information Services (IIS) Simple Mail Transfer Protocol (SMTP) mail relay server. IIS in Windows Server 2003 includes a full-featured SMTP virtual server that you can use to deliver messages on your internal network. The SMTP virtual server can also be used to accept messages from the Internet. Although the SMTP service does not provide an easily accessible message retri
