solr master-slave cluster 2

I want to use nginx 1.4.4 for load balancing. I have never been exposed to it before and many problems occurred. I will record them bit by bit.

1. root /html; and root html; the former refers to the path under the drive letter, and the latter is the path under the nginx root directory, such as E:/html/index.html and E:/nginx-1.4.4/ html/index.html

2. Start nginx has been executed multiple times, and there are many nginx processes in the process. Modifying nginx.conf later will be invalid

3. The two ports of proxy_set_header Host $host:port; and listen port are consistent

4. You can only set ip and port in upstream, but you need to use the project address/aaa when accessing.

There are several methods: 1. Manually add the project address http://server_name/aaa

2. Change aaa to ROOT

3. Use proxy_pass http://backend/aaa/; but there will be problems accessing other addresses in the project

4. proxy_pass http://backend; rewrite ^/$ /aaa last; this will Automatically add /aaa to the address

If you have a better way, please leave a message.

The above introduces the Solr master-slave cluster 2, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
