环境搭建
JDK准备
1.卸载原有的JDK
[doudou@hadoop101 software]$ tar -zxvf jdk-8u212-linux-x64.tar.gz -C /opt/module/
2.把准备好的JDK拖到xshell里安装新的JDK
3.配置环境变量并分发
[doudou@hadoop101 opt]$ cd module/
[doudou@hadoop101 module]$ ll
total 0
drwxr-xr-x. 7 doudou root 245 Apr 1 2019 jdk1.8.0_212
[doudou@hadoop101 module]$ cd jdk1.8.0_212/
[doudou@hadoop101 jdk1.8.0_212]$ pwd
/opt/module/jdk1.8.0_212
[doudou@hadoop101 jdk1.8.0_212]$ sudo vim /etc/profile.d/my_env.sh
#JAVA_HOME
export JAVA_HOME=/opt/module/jdk1.8.0_212
export PATH=$PATH:$JAVA_HOME/bin
[doudou@hadoop101 jdk1.8.0_212]$ source /etc/profile.d/my_env.sh
[doudou@hadoop101 jdk1.8.0_212]$ java -version
java version "1.8.0_212"
Java(TM) SE Runtime Environment (build 1.8.0_212-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.212-b10, mixed mode)
[doudou@hadoop101 module]$ xsync jdk1.8.0_212/
日志生成
1.来到目录下把准备好的日志拖到进入的文件夹中
[doudou@hadoop101 applog]$ ll
total 15288
-rw-r--r--. 1 doudou root 979 Aug 6 22:35 application.yml
-rw-r--r--. 1 doudou root 15640308 Aug 6 22:35 gmall2020-mock-log-2021-01-22.jar
drwxr-xr-x. 2 doudou root 32 Aug 6 22:43 log
-rw-r--r--. 1 doudou root 1039 Aug 6 22:35 logback.xml
-rw-r--r--. 1 doudou root 565 Aug 6 22:35 path.json
[doudou@hadoop101 applog]$
2.生成对应的日志
[doudou@hadoop101 applog]$ java -jar gmall2020-mock-log-2021-01-22.jar
查看：会出现log
[doudou@hadoop101 applog]$ ll
total 15288
-rw-r--r--. 1 doudou root 979 Aug 6 22:35 application.yml
-rw-r--r--. 1 doudou root 15640308 Aug 6 22:35 gmall2020-mock-log-2021-01-22.jar
drwxr-xr-x. 2 doudou root 32 Aug 6 22:43 log
-rw-r--r--. 1 doudou root 1039 Aug 6 22:35 logback.xml
-rw-r--r--. 1 doudou root 565 Aug 6 22:35 path.json
进入log，查看对应日志
[doudou@hadoop101 applog]$ cd log/
[doudou@hadoop101 log]$ ll
total 772
-rw-r--r--. 1 doudou root 788755 Aug 6 22:43 app.2022-08-06.log
