Linux consolidation Records (1) Java EE Development Environment construction and network configuration

It's a lot more time to operate Linux due to the recent use of Hadoop and other related tasks.

Previously, only the Java EE Project execution Environment was configured on Linux, with the provision of a JDK, deployment of Tomcat, and automatic deployment via Docker or Jenkins

Look at the process, copy and paste deletion and other basic operations, a lot of things for a long time forget, all write a demo to consolidate the Linux knowledge

Follow-up will be the mainstream of Hadoop and other major data-related environment to build and use

--------------------------------------------------------------------------------------------------------------- ------------------------------------------

This talk about the most basic Java EE environment to build VMware 12 under Centos-7-x86_64-everything

1. The virtual machine is configured as a static address and in the same network segment (try not to use DHCP, if the IP is changed, it will affect such as the network between Hadoop nodes is not through)

A is configured as a static address and the specified network segment and host are the same

Edit "Virtual Network Editor" VMnet8 "

　　

　　

When a virtual machine is selected, right-click Settings network adapter is set to bridge mode

　　

　　

After entering the system vi/etc/sysconfig/network-scripts/ifcfg-enxxxx the last point may not be the same, please confirm the change to the following similar

Type= "Ethernet" bootproto= "static" defroute= "yes" peerdns= "yes" peerroutes= "yes" ipv4_failure_fatal= "no" ipv6init= "yes" ipv6_autoconf= "yes" ipv6_defroute= "yes" ipv6_peerdns= "yes" ipv6_peerroutes= "yes" ipv6_failure_fatal= "No" ipv6_addr_gen_mode= "Stable-privacy" name= "Ens33" uuid= "0689ca28-6b38-4226-b55a-e2e5a2825556" DEVICE= "Ens33" onboot= "Yes"ipaddr=192.168.0.80netmask=255.255.255.0gateway=192.168.0.1dns1=61.139.2.69

Also shuts down the firewall and disables boot booting

Systemctl Stop Firewalld.service systemctl disable Firewalld.service

Reboot the system and verify that it is able to ping each other with the host

If the virtual machine and host are not on the same network segment, you need to increase the routing to ping the

Route-p Add 192.168.65.0 255.255.255.0 192.168.0.168

2. Configuring the JDK

The full version of the system comes with OPENJDK and is replaced with Oracle's JDK

First, the OpenJDK uninstall

#查找带有openjdk的安装项目rpm-qa | grep java# Delete rpm-e--nodeps by name xxxxx

Download the Linux version jdk to the/home directory and pass the tar--xzvf jdk-xxxx.tar.gz/jdk1.8.0

Vi/etc/profile

and add the following content,

Export Java_home=/home/jdk1.8.0export classpath=.: $JAVA _home/jre/lib/rt.jar: $JAVA _home/lib/dt.jar: $JAVA _home/lib /tools.jarexport path= $PATH: $JAVA _home/bin export Java_homeexport pathexport CLASSPATH

Make configuration effective immediately

#立即生效source/etc/profile

Confirm the configuration is successful by java-version

In the same way, other things like Maven are consistent with the JDK configuration, which can be added to the path in/etc/profile after decompression.

Tomcat can be extracted directly via Ps-ef | grep "Tomcat" to view the running status
