), generally choose zabbix/cacti monitoring software.Selection of serversAll with stability as the premise and principle, in the case of price can be accepted by the company, you can choose a brand server like IBM and Dell, the quality is guaranteed.When server resources are tight, OpenStack virtualization (KVM) can be deployed, and virtual machines can act as test machines, beta machines, and internal deployment machines to take advantage of machine resources.(2)

1.HAProxy Introduction Haproxy is an open-source, high-performance, load-balancing software based on TCP (four-tier), HTTP (seven-tier) applications. That haproxy as a professional load balancer software, it has the following advantages: Very good reliability and stability, comparable to hardware-level F5

The VIP is on the master, and the round robin is switched to one of the servers. (The data volume of each customer is different, and redis is basically a persistent connection. Unlike Http, it is not completely load balancing) Master s

Brief introductionHaproxy is a free and open source software written in the C language that provides high availability, load balancing, and application proxies based on TCP and HTTP. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. The haproxy runs on the current hardware and can support tens of thousands of concurrent connections.

WebLogic load Balancing can be achieved by means of software and hardware. Hardware can use F5 and other devices, software generally use Apache to achieve. Here's how to use Apache. WebLogic load Balancing can be achieved by means of software and hardware. Hardware can use

Website access speed and enhancing website availability and security. DNS round robin and squid reverse proxy can be used to achieve Load Balancing for websites, thus improving the availability and reliability of websites. The reverse proxy server is also called the Web Acceleration Server.It is located at the front end of the web server and serves as the conten

18.6 Load Balancing Cluster introductionThe software that realizes load Balancing cluster is: LVS, keepalived, Nginx, Haproxy and so on. The LVS belong to four layer (network OSI model), Nginx belongs to seven layer, haproxy can be considered as four layer, also can be used as seven layer.LVS, Haproxy this four-tiered

server list is not changed.4. Weighted round-robin methodDifferent back-end servers may not have the same machine configuration and current system load, so they have varying compression capabilities. Configure a high, low-load machine with higher weights to handle more requests, and configure low, high-load machines,

DNS load balancing is the first implementation of load balancing technology. Configuring the same name for multiple addresses in a DNS configuration file is configured with multiple A records pointing to a different IP, and the client will randomly obtain one of the addresses when querying this a record. It is not diff

on the Web server. (1) The upstream command of the scheduling algorithm nginx is used to specify the backend servers used by proxy_pass and fastcgi_pass, that is, the reverse proxy function of nginx, therefore, the two can be combined to achieve load balancing, while nginx also supports multiple scheduling algorithms: 1. Round Robin (default) each request is dis

If there are high requirements for data reliability in the future, it will work with dump and master slave.

When a redis-server/server crashes, the VIP will be transferred to another server, but the backup server will be idle, our company is small and cannot be

Linux-Nginx simple Load Balancing (1), linux-nginx Here we will perform simple nginx load first, and we will not talk about nginx installation here. We assume that nginx has been installed: 1) check whether the upstrea Server Load balancer module in nginx is installed by default. Go to the nginx source code directory.

Max_fails: the default number of failed requests is 1. If the maximum number of failed requests is exceeded, an error defined by the proxy_next_upstream module is returned. Fail_timeout: The pause time after max_fails failed. Iii. Server
