Maven,yum,apt,nodejs

Nexus3 is a repository manager that greatly simplifies the maintenance of local internal repositories and the access to external repositories. Normally, we get maven repository resources from the official (or domestic mirror) of Maven, but if your production server does not have Internet access, At this point, it is necessary to set up a private warehouse on a server with Internet access permission on the LAN, so that other servers with Internet access permission can download and install Maven, APT, yum, Gradle, pypi, Docker and so on through the established private repository, just like downloading directly through the Internet.

Nexus support: Nexus in the remote warehouse while maintaining the local warehouse, to reduce the load of the central warehouse, save the bandwidth and time of the external network, Nexus private server can meet such needs. Nexus is an “out of the box” system that doesn’t need a database, but uses a file system plus Lucene to organize data. Nexus supports WebDAV and LDAP secure authentication. Nexus also offers powerful warehouse management, component search, reST-based, low memory footprint, and simple file systems instead of databases.

1. The JDK installation

Nexus3 is developed in Java and requires Jdk installation

Prepare the JDK-8u191-linux-x64.tar.gz ######## Decompress to the /usr/local directory: tar -xvf JDK-8u191-linux-x64.tar.gz -c /usr/local ######## Configure the JDK environment variable cat >> /etc/profile << EOFexport JAVA_HOME=/usr/local/jdk18.. 0_191 /export PATH=\$JAVA_HOME/bin:\$PATH
exportCLASSPATH=.:\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar EOF ######## Run the environment variables to take effect source /etc/profile ######## View Java -versionCopy the code

2. Install the Nexus software

Take nexus-3.29 as an example. Prepare nexus-3.29.1-01-UNIX.tar. gz

######## decompress mkdir /usr/local/nexus3 tar -xvf nexus3.291.- 01-unix.tar.gz -C /usr/local/nexus3
Copy the code

Nexus-3.29.1-01 is the program and Sonatype -work is the data directory

[root@localhost nexus3]# cd /usr/local/nexus3/
[root@localhost nexus3]# ls -hl
total 0
drwxr-xr-x. 9 root root 163 Jun 28 10:47 nexus3.291.- 01
drwxr-xr-x. 3 root root  20 Jun 28 10:47 sonatype-work
Copy the code

3. Modify the configuration

The Jvm configuration is in /usr/local/nexus3/nexus-3.29.1-01/bin/nexus.vmoptions

For example, if the memory is small, adjust VM parameters. The reference values are as follows

-Xms500M -Xmx500M -XX:MaxDirectMemorySize=800M

The default storage directory is nexus-3.29.1-01 in the installation directory. For example, if you want to change this to another directory, you can change the values of karaf.data, karaf.log, java.io

-Dkaraf.data=.. /sonatype-work/nexus3 -Dkaraf.log=.. /sonatype-work/nexus3/log -Djava.io.tmpdir=.. /sonatype-work/nexus3/tmp

/usr/local/nexus3/nexus-3.29.1-01/etc/nexus-default.properties /usr/local/nexus3/nexus-3.29.1-01

Port modification:

Sed -i ‘s/application – port = 8081 / application – port = 80 /’/usr/local/nexus3 / nexus – 3.29.1-01 / etc/nexus – default. The properties

Nexus – context – path changes

sed -i ‘s/nexus-context-path=//nexus-context-path=/nexus3/’ / usr/local/nexus3 / nexus – 3.29.1-01 / etc/nexus – default. The properties

4. Start, restart, and stop

/usr/local/nexus3/nexus3.291.- 01/bin/nexus start
/usr/local/nexus3/nexus3.291.- 01/bin/nexus restart
/usr/local/nexus3/nexus3.291.- 01/bin/nexus stop
Copy the code

5. Access tests

During the test, I changed /nexus-context-path to /nexus3, so the access address is as follows:http://192.168.56.101:8081/nexus3/ admin admin123

Maven,yum, APT, Docker, NPM private library construction

Maven private library:

Maven.aliyun.com/repository/… Maven.aliyun.com/repository/… Maven.aliyun.com/repository/… Maven.aliyun.com/repository/…

Yum private library:

3. Use of private libraries

Yum private library

Back up the old configuration, execute the new configuration, then yum Clean all to clear the cache, then do the normal yum install operation

cd /etc/yum.repos.d/
mkdir bak
mv *.repo bak
