Then install jdk:

// First retrieve the list containing java yum list java * // then retrieve the list of 1.8 yum list java-1.8 * // and install all the files of 1.8.0 yum install java-1.8.0-openjdk *-y

How can I check if nginx has been installed on centos7:

If you install nginx with an rpm package, run the following command:

nginx -V　　

If you are compiling and installing the source code package and your installation path is/usr/local/nginx, you can use:

/usr/local/nginx/sbin/nginx -V

Note that it is written in uppercase, so that you can see the modules loaded by nginx.
