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

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 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

[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

nexus-aliyun

*

Nexus aliyun

http://maven.aliyun.com/nexus/content/groups/public

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

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

[Install]

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.

Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

在mysql中创建dblog库即可； ##这里是项目需要dblog数据库

3306 [(none)]>create database dblog charset utf8mb4;

Query OK, 1 row affected (0.00 sec)

3306 [(none)]>

[root@localhost ~]# mysql -uroot -p123456 dblog < /opt/DBlog/docs/db/dblog.sql

mysql: [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

[root@localhost config]# pwd

/opt/DBlog/blog-core/src/main/resources/config

[root@localhost config]# ll

-rw-r--r--. 1 root root 190 May 1 23:44 application-center.yml

[root@localhost config]# vim application-center-dev.yml #只需修改数据库的密码，redis的链接地址和密码即可

[root@localhost config]# vim application-center-test.yml #该文件和上面文件修改完全一样，只截一张图说明

项目根目录下执行mvn -X clean package -Dmaven.test.skip=true -Ptest编译打包(注：-Ptest中的test为环境标识)，然后cd到blog-web目录下执行java -jar target/blog-web.jar

[root@localhost DBlog]# ll

测试环节：浏览器访问http://127.0.0.1:8443   这是前端

浏览器检查：

浏览器访问http://127.0.0.1:8443       这是后台

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。
