After configuring MySQL 's master-slave replication structure, we want to implement read-write separation, spread the reads to the slave server, and load balance multiple slave servers. read-write separation and load balancing are the basic requirements of MySQL cluster, and M

cannot detect it and will not forward the request. The common advantage of R-proxy and mod_jk is that only Apache can be deployed on the public network, saving public IP Address resources. Apache can handle static web pages through settings, so Tomcat can handle dynamic requests such as JSP and servlet. The common disadvantage is that if the front-end Apache proxy server stops running, all cluster services cannot be provided externally. R-proxy and mod_jk can be used to select an optimal effect

Use lvs keepalived to configure redis high availability and load balancing, lvsredisRequirement We use elasticsearch for log service. The architecture is upstream data source => redis => logstash => ES Redis is still a single point of use, and there is no high availability. Now there is more and more data. If downstream consumption is not a problem, it will take place if data in redis comes, but once the do
