In order to enable the company's developers to package the java project faster, there is no need to download related jar packages on the public Internet every time.
Build a Nexus private warehouse, this component has two versions of paid and community, if there is a network problem when downloading, you can use this link to download the software package next week -------- http://www.liyuanshu.top:83/nexus -3.22.1-02-unix.tar.gz
The working principle is as follows:
Operating procedures:
First, install the JDK environment
2. After downloading the Nexus installation package, directly decompress it and start it with the script
[root@localhost /usr/local/nexus-3.22.1-02/bin]# ./nexus run
Note: This time the nexus service is installed in Centos, and it has always been reported to be wrong when it is started during Ubuntu system installation. In addition, 2G of memory space is required, and the startup time is longer. . .
After successful startup, you can see the 8081 default port is activated.
You can access it after entering the server IP address and port. It has been modified to listen on port 80 -------- http: //192.168.1.127/, initial account: admin password: admin:
Modify the Nexus execution public warehouse to Alibaba Cloud warehouse, which is faster to download. http://maven.aliyun.com/nexus/content/groups/public/
