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
[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
export PATH=/usr/local/maven/bin:$PATH source /etc/profile
检查版本信息
[root@localhost /]# mvn -v Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00) Maven home: /usr/local/maven Java version: 1.8.0_181, vendor: Oracle Corporation Java home: /usr/java/jdk1.8.0_181-amd64/jre Default locale: en_US, platform encoding: UTF-8 OS 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）
[root@localhost /]# rpm -ivh jdk-8u181-linux-x64.rpm
warning: jdk-8u181-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

查看版本安装是否成功
[root@localhost /]# java -version java 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
[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]# ls DBlog
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
[root@localhost opt]# cd /usr/local/maven/conf/ [root@localhost conf]# ls logging 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
[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/profile export 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 -V mysql 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
[root@localhost app]# useradd mysql [root@localhost app]# mkdir /data/mysql -p [root@localhost app]# chown -R mysql.mysql /app/* [root@localhost app]# chown -R mysql.mysql /data/* [root@localhost app]# mysqld --initialize-insecure --user=mysql --basedir=/app/mysql --datadir=/data/mysql 2019-05-01T16:11:19.720627Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

[root@localhost app]# cd /data/mysql/ [root@localhost mysql]# ll total 110628 -rw-r-----. 1 mysql mysql 56 May 2 00:11 auto.cnf -rw-r-----. 1 mysql mysql 419 May 2 00:11 ib_buffer_pool -rw-r-----. 1 mysql mysql 12582912 May 2 00:11 ibdata1 -rw-r-----. 1 mysql mysql 50331648 May 2 00:11 ib_logfile0 -rw-r-----. 1 mysql mysql 50331648 May 2 00:11 ib_logfile1 drwxr-x---. 2 mysql mysql 4096 May 2 00:11 mysql drwxr-x---. 2 mysql mysql 8192 May 2 00:11 performance_schema drwxr-x---. 2 mysql mysql 8192 May 2 00:11 sys
添加配置文件
[root@localhost mysql]# vim /etc/my.cnf [root@localhost mysql]# mv /etc/my.cnf /opt/my.cnf.bak [root@localhost mysql]# vim /etc/my.cnf [mysqld] user=mysql basedir=/app/mysql datadir=/data/mysql server_id=6 port=3306 socket=/tmp/mysql.sock [mysql] socket=/tmp/mysql.sock prompt=3306 [\d]> [root@localhost mysql]# cp /app/mysql/support-files/mysql.server /etc/init.d/mysqld [root@localhost mysql]# service mysqld start|stop|restart ###这里和上一步是为了使用service命令控制服务， [root@localhost mysql]# vim /etc/systemd/system/mysqld.service ###如果上面的方式不爽，想用systemctl命令需要这样设置 [Unit] Description=MySQL Server Documentation=man:mysqld(8) Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html After=network.target After=syslog.target [Install] WantedBy=multi-user.target [Service] User=mysql Group=mysql ExecStart=/app/mysql/bin/mysqld --defaults-file=/etc/my.cnf LimitNOFILE = 5000 [root@localhost mysql]# mysqladmin -uroot -p password 123456 Enter password: ###这里直接回车，因为初始状态没设置密码 mysqladmin: [Warning] Using a password on the command line interface can be insecure.

[root@localhost ~]# mysql -uroot -p123456 dblog < /opt/DBlog/docs/db/init_data.sql mysql: [Warning] Using a password on the command line interface can be insecure.
安装配置redis
yum -y install redis [root@localhost opt]# vim /etc/redis.conf #编辑之前做好这个文件的备份，别问我为什么，这是运维的基本素养 61 bind 192.168.171.144 ###这个61是行数，设置服务器的ip，不要使用127.0.0.1的地址 479 equirepass 123456 ###479是行数，设置密码 root@localhost opt]# systemctl restart redis [root@localhost opt]# ps -ef |grep redis redis 13042 1 0 00:52 ? 00:00:00 /usr/bin/redis-server 192.168.171.144:6379 root 13047 2452 0 00:52 pts/1 00:00:00 grep --color=auto redis
对项目开始动手了

开启项目的前端和后台
[root@localhost DBlog]# cd blog-web/ [root@localhost blog-web]# ls pom.xml src target [root@localhost blog-web]# ll total 4 -rw-r--r--. 1 root root 1575 May 1 23:44 pom.xml drwxr-xr-x. 4 root root 30 May 1 23:44 src drwxr-xr-x. 6 root root 137 May 2 01:08 target [root@localhost blog-web]# java -jar target/blog-web.jar & ###前端 [root@localhost DBlog]# cd blog-admin/ [root@localhost blog-admin]# ll total 4 -rw-r--r--. 1 root root 1942 May 1 23:44 pom.xml drwxr-xr-x. 4 root root 30 May 1 23:44 src drwxr-xr-x. 6 root root 141 May 2 01:08 target [root@localhost blog-web]# java -jar target/blog-admin.jar & ###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。
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。
