极力推荐大佬的java项目的博客
此次说明：这是我从码云上拉取下来的java项目，仅供试验说明，不做任何获利渠道，若是发现有人拿此做其他用处，需像码云上这位大佬说明，特此感谢！！！
准备工作：
安装 maven，jdk1.8，下载项目（DBlog），mysql，redis，git
下载Maven 3安装包官网：http://maven.apache.org/download.cgi
清华镜像：https://mirrors.tuna.tsinghua.edu.cn/apache/maven/
老夫下载好的软件=====>>>>>链接：https://pan.baidu.com/s/1jHYfVGKOEM4WuU9OOaEvYQ 提取码：uutl
安装Maven
1 2 | [root@localhost opt]#tar xf apache‐maven‐3.3.9‐bin.tar.gz[root@localhost opt]# mv apache-maven-3.3.9 /usr/local/maven |
编辑/etc/profile文件
1 2 | export PATH=/usr/local/maven/bin:$PATHsource /etc/profile |
检查版本信息
1 2 3 4 5 6 7 | [root@localhost /]# mvn -vApache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)Maven home: /usr/local/mavenJava version: 1.8.0_181, vendor: Oracle CorporationJava home: /usr/java/jdk1.8.0_181-amd64/jreDefault locale: en_US, platform encoding: UTF-8OS name: "linux", version: "3.10.0-693.el7.x86_64", arch: "amd64", family: "unix" |
安装jdk1.8版本（只要是1.8即可，随便那种方式安装都行）
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | [root@localhost /]# rpm -ivh jdk-8u181-linux-x64.rpmwarning: jdk-8u181-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEYPreparing... ################################# [100%]Updating / installing... 1:jdk1.8-2000:1.8.0_181-fcs ################################# [100%]Unpacking JAR files... tools.jar... plugin.jar... javaws.jar... deploy.jar... rt.jar... jsse.jar... charsets.jar... localedata.jar... |
查看版本安装是否成功
1 2 3 4 | [root@localhost /]# java -versionjava version "1.8.0_181"Java(TM) SE Runtime Environment (build 1.8.0_181-b13)Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode) |
在码云上下载博客资源
特别说明：获取资源链接地址，开始下载，有安装git的可以使用git clone+链接的方式下载，没有的话只能安装git因为链接资源是git文件，其他方式下载打不开的
这里安装并设置下git，然后下载项目资源
1 2 3 4 5 6 7 8 9 10 11 12 | [root@localhost opt]# yum -y install git[root@localhost opt]# git init #初始化仓库，不过注意此仓库不要有其他文件[root@localhost opt]# git clone https://gitee.com/yadong.zhang/DBlog.git #https这就是从码云上获取的链接Cloning into 'DBlog'...remote: Enumerating objects: 6356, done.remote: Counting objects: 100% (6356/6356), done.remote: Compressing objects: 100% (3022/3022), done.remote: Total 6356 (delta 3147), reused 4916 (delta 2417)Receiving objects: 100% (6356/6356), 6.87 MiB | 3.32 MiB/s, done.Resolving deltas: 100% (3147/3147), done.[root@localhost opt]# lsDBlog |
将下载地址换成阿里云
原因：因为原地址是国外的，对于我们来说获取资源太慢，所以换成了国内的，比如阿里云
1 2 3 4 5 6 7 8 9 10 11 | [root@localhost opt]# cd /usr/local/maven/conf/[root@localhost conf]# lslogging settings.xml toolchains.xml[root@localhost conf]# cp settings.xml settings.xml.bak[root@localhost conf]# vim settings.xml ####将下面这段代码复制到相应代码行即可<mirror> <id>nexus-aliyun</id> <mirrorOf>*</mirrorOf> <name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror> |
安装mysql，redis并配置
先配置mysql
1 2 3 4 5 6 7 8 9 10 11 12 13 | [root@localhost opt]# mkdir /app将mysql二进制包放进来后解压[root@localhost app]# tar -xf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz改名[root@localhost app]# mv mysql-5.7.20-linux-glibc2.12-x86_64/ mysql设置变量[root@localhost app]# vim /etc/profileexport PATH=/app/mysql/bin:$PATH激活变量[root@localhost app]# source /etc/profile查看版本，意味着变量设置成功[root@localhost app]# mysql -Vmysql Ver 14.14 Distrib 5.7.20, for linux-glibc2.12 (x86_64) using EditLine wrapper |
添加mysql用户，设置授权目录并初始化

开启项目的前端和后台

测试环节：
浏览器检查：
浏览器检查（登录用户admin。密码123456）
事实上，上面的命令仅能保证xshell不退出有效，一旦退出自动杀掉了进程，所以为了退出xhsell进程不杀死java进程，可以使用下面的命令。
1 2 3 | 在主目录下使用下面两条命令，可以自定义访问端口，并且安全的放在后台nohup java -jar blog-web/target/blog-web.jar --server.port=8000 2>&1 &nohup java -jar blog-admin/target/blog-admin-2.2.1.jar --server.port=8001 2>&1 & |
后话：当我们去点击无论是前端还是以后台时，服务器内部的日志信息会刷新，提示写入redis缓存当中，等等这些，大有搞头，小伙伴们有兴趣可以试试。
