一款模仿天猫的在线购物网站，基于centos7.9搭建

搭建数据库

官网下载软件包后上传

基于centos7.9搭建mysql5.6.42

[root@mysql02 ~]# ls
anaconda-ks.cfg  init.sh  MySQL-5.6.42-1.el7.x86_64.rpm-bundle.tar

解压

tar -xf MySQL-5.6.42-1.el7.x86_64.rpm-bundle.tar -C /opt/

[root@mysql02 ~]# ls /opt/
MySQL-client-5.6.42-1.el7.x86_64.rpm    MySQL-server-5.6.42-1.el7.x86_64.rpm         MySQL-test-5.6.42-1.el7.x86_64.rpm
MySQL-devel-5.6.42-1.el7.x86_64.rpm     MySQL-shared-5.6.42-1.el7.x86_64.rpm
MySQL-embedded-5.6.42-1.el7.x86_64.rpm  MySQL-shared-compat-5.6.42-1.el7.x86_64.rpm

检测是否有其他版本mysql，否则卸载

rpm -qa | grep -i mysql
rpm  -qa  |  grep  mariadb
rpm  -e  --nodeps  mariadb-libs-5.5.68-1.el7.x86_64

使用yum进行安装，注意搭配centos源

mount /dev/sr0 /mnt/
mv /etc/yum.repos.d/* /home/
cat > /etc/yum.repos.d/c.repo <<eof
[c]
name=c
baseurl=file:///mnt
gpgcheck=0
enabled=1
eof

[root@mysql02 ~]#

yum install -y /opt/*

配置my.cnf，并且需要跳过验证，设置密码，或者命令也可，二者选一

使用命令方式需要在数据库停止状态下使用，然后新开一个窗口进入数据库

 mysqld_safe --skip-grant-tables &

新开窗口执行

 mysql -uroot -p

USE mysql;
UPDATE user SET password=PASSWORD('123456') WHERE user='root';
FLUSH PRIVILEGES;

关闭mysqld_safe --skip-grant-tables &启动窗口后重启

systemctl restart mysql

mysql -uroot -p123456
SET PASSWORD = PASSWORD('123456');
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
FLUSH PRIVILEGES;

关闭防火墙和selinux

setenforce 0
systemctl stop firewalld

即可测试远程访问

PS C:\Users\huhy> mysql -h 192.168.200.100 -uroot -123456

配置Java

下载jdk1.8，然后上传到centos上

```python
[root@localhost ~]# ls jdk-8u144-linux-x64.tar.gz
jdk-8u144-linux-x64.tar.gz

解压到

mkdir -p /usr/local/java
tar -zxvf jdk-8u144-linux-x64.tar.gz -C /usr/local/java/

配置环境变量

vi /etc/profile

export JAVA_HOME=/usr/local/java/1.8.0_144
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

ln -s /usr/local/java/jdk1.8.0_144/bin/java /usr/bin/java

[root@localhost ~]# source /etc/profile
[root@localhost ~]# java -version
java version "1.8.0_144"

[root@localhost ~]#

配置jar包

yum install -y unzip
yum install -y zip

上传TmallDemo.jar

mkdir -p /u01/apps/mall
cd /u01/apps/mall
mv TmallDemo.jar .

编辑配置文件

vim TmallDemo.jar

找到并修改BOOT-INF/classes/application-prod.yml
