Linux上部署Java应用

Posted 2021-02-07 hello-yz

给了Linux的测试环境，目前需要install JDK, Tomcat，此处记录下小白的操作过程。

1. 查询Linux发行版本，包括内核信息

(1) Linux查询内核信息

$ uname -a

Linux ECA-LPH000007 3.10.0-514.6.1.el7.x86_64 #1 SMP Wed Jan 18 13:06:36 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

$ cat /proc/version

Linux version 3.10.0-514.6.1.el7.x86_64 ([email protected]centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) #1 SMP Wed Jan 18 13:06:36 UTC 2017

大概猜出发行版CentOS 7, 64位

(2) Linux查询发行版

$ lsb_release -a

-bash: lsb_release: command not found

命令不支持

$ cat /etc/issue

S
Kernel on an m

没有具体版本信息

$ ls -l /etc | grep release
$ cat /etc/centos-release

-rw-r--r--. 1 root root 38 Dec 9 2015 centos-release
-rw-r--r--. 1 root root 51 Dec 9 2015 centos-release-upstream
-rw-r--r--. 1 root root 393 Dec 9 2015 os-release
lrwxrwxrwx. 1 root root 14 Mar 17 2017 redhat-release -> centos-release
lrwxrwxrwx. 1 root root 14 Mar 17 2017 system-release -> centos-release
-rw-r--r--. 1 root root 23 Dec 9 2015 system-release-cpe

CentOS Linux release 7.2.1511 (Core)

确认CentOS 7, 64位发行版。

2. 是否安装JDK

$ java -version

-bash: java: command not found

$ which java

/usr/bin/which: no java in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/xxx/.local/bin:/home/xxx/bin)

确认无JDK配置
