Can't find phpize on older versions of CentOS, can't compile php extensions. How to install phpize?
Maybe in the old version of the docker environment, when using Docker compose to start the container, you will encounter the following error: Error response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network This is actually this It is a symptom of running out of default-address-pools. In some environments, docker-compose will use the private network of Class B by default. The private IP of segment 172 has a range, from 172.16.0.0 to 172.31.255.255. That is to say, when we start a docker-compose Project, it will eat a private section of Class B, which is very heroic.
