ubuntu24.04 搭建 java 环境服务，以及mysql数据库

安装 nginx

安装 nginx

sudo apt update
apt-get install nginx

nginx 检查 安装环境以及配置文件地址

nginx -t

检查环境是否正常

systemctl status nginx.service

重启 nginx 服务

systemctl restart nginx.service

停止 nginx 服务

# 停止
systemctl stop nginx.service

启动 nginx 服务

# 启动
systemctl start nginx.service

nginx 项目使用端口 配置文件配置方式

server {listen 8082 default_server;listen [::]:8082 default_server;root /mnt/data/system/tms/dist;location / {try_files $uri $uri/ /index.html;index  index.html index.htm;}location /prod-api/ {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header REMOTE-HOST $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://127.0.0.1:8080/;}
}

📌 功能说明：

• 监听 IPv4 和 IPv6 的 8082 端口；
• 根目录指向前端打包文件（Vue/React 等）；
• 对根路径 / 使用了 try_files 来支持前端路由；
• 对 /prod-api/ 路径做反向代理到本地 8080 接口服务。

# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.

#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.
#
# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
### Default server configuration
#
server {listen 8082 default_server;listen [::]:8082 default_server;root /mnt/data/system/tms/dist;location / {try_files $uri $uri/ /index.html;index  index.html index.htm;}location /prod-api/ {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header REMOTE-HOST $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://127.0.0.1:8080/; }
}
server {listen 8083 default_server;listen [::]:8083 default_server;root /mnt/data/system/tms/work;location / {try_files $uri $uri/ /index.html;index  index.html index.htm;}location /prod-api/ {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header REMOTE-HOST $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://127.0.0.1:8080/; }
}

nginx文件安装完成之后的文件位置：

• /usr/sbin/nginx：主程序
• /etc/nginx：存放配置文件
• /usr/share/nginx：存放静态文件
• /var/log/nginx：存放日志
  

mysql

安装mysql

sudo apt update
# 下载mysql 默认版本一般是 8.0.19
sudo apt-get install mysql-server
# 安装mysql开发包
sudo apt install -y libmysqlclient-dev
# 设置mysql server开机自启
sudo systemctl enable mysql
# 设置安全内容，启动配置第一次会让你输入密码，或者执行时 选择忽略密码，后续配置完返回再次执行这个
sudo mysql_secure_installation
# 启动
sudo service mysql start

检查 mysql 是否正常启动

sudo service mysql status

碰到以下问题

Warning: The unit file, source configuration file or drop-ins of mysql.service changed on disk. Run 'systemctl daemon-reload' to reload units.

麻烦 重启systemd管理器

systemctl daemon-reload

开放用户远程登录权限

# 第一次没配置密码可以直接进入
mysql -uroot -p# 进去mysql 数据库
use mysql;# 查询用户， 可以用 更新语句把 host 只为 localhost 的root 用户开放 修改为 %
select User,host from user;
# 刷新
FLUSH TABLES‌;

开放mysql配置远程登录权限

进入修改文件页面

vim /etc/mysql/mysql.conf.d/mysqld.cnf
# 修改 bind-address = 0.0.0.0
# 添加 character_set_server=utf8
#重启 msyql
service mysql restart

安装 openjdk 17

sudo apt update
# 检查是否以及安装过
java -version

安装OpenJDK
默认是最新的

sudo apt install default-jdk

安装自己需要的版本

sudo apt install openjdk-8-jdk
sudo apt install openjdk-11-jdk
sudo apt install openjdk-17-jdk
sudo apt install openjdk-21-jdk

检查是否安装完成

java -version
