1、安装jdk
更新软件源
sudo apt-get update
搜索jdk
sudo apt search openjdk
安装 OpenJDK 8
sudo apt install openjdk-jdk8
查看是否安装成功
java -version
2、安装mysql
参考了：blog.csdn.net/u014378628/…
注意：Ubuntu20.0.4后默认的 mysql 是 mysql8，可以直接安装
安装mysql8
apt install mysql-server
查看mysql 服务状态
systemctl status mysql
查看版本
mysql --version
linux中在 mysql8 后，mysql 的 root 登录方式是使用系统身份登录认证，可以看到 root 账户的 plugin是 auth_socket。auth_socket 是 MySQL 的一种用户身份验证插件，它是基于系统用户的身份进行认证的。当使用 auth_socket 插件时，MySQL 将使用操作系统的用户和组信息来检查用户是否有权限访问 MySQL 服务器。
具体来说，如果一个 MySQL 用户账户使用 auth_socket 插件进行身份验证，则只有拥有该用户账户同名的系统用户才能登录到 MySQL 服务器。
root@iZ7xvcns9k722thqiufsvnZ:/home/laibin# mysql --version
mysql Ver 8.0.35-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))
root@iZ7xvcns9k722thqiufsvnZ:/home/laibin# mysql

我们需要修改root的加密规则，将其改为密码登录，其中 new_password 是自己想设置的代码。
ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'new_password';
退出后即可使用密码登录了，后面就可以在代码里面使用账号密码进行连接数据库了，但是需要其他账号的话需要自己新建。
mysql -u root -p
默认情况下，mysql服务器监听本地回环地址（127.0.0.1），如果需要从其他计算机连接，需要将其更改为适当的 IP 地址。
vim /etc/mysql/mysql.conf.d/mysqld.cnf
在该文件中修改 bind-address 字段
bind-address= 127.0.0.1 修改为 bind-address= 0.0.0.0
给 root 用户启用 GRANT OPTION 权限
ALTER USER 'root'@'%' WITH GRANT OPTION;
新建用户并授权远程连接数据库，对所有数据库都有增删改查创建删除功能，然后刷新权限
CREATE USER 'laibin'@'%' IDENTIFIED BY 'laibin用户密码';
GRANT ALL PRIVILEGES ON *.* TO 'laibin'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
重启服务
service mysql restart
之后用navicat等数据库可视化工具就可以连接上了，连接用户是新建的laibin。
记得要在阿里云控制台的安全组开放3306端口。
3、安装redis
更新数据源
apt update
查询redis-server
apt search redis-server
安装redis-server
apt install redis-server
安装完成后，Redis 会自动启动。你可以使用以下命令检查 Redis 是否正在运行：
systemctl status redis
连接 redis
redis-cli
远程连接redis，将bind 127.0.0.1 ::1 ，改为bind 0.0.0.0
################################## NETWORK #####################################
# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 loopback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1 ::1
开放6379端口
4、安装nginx
4.1、apt包管理器下载
安装nginx
apt install nginx
安装的nginx默认在/etc目录下，静态资源在/var/www/html/，日志在/var/log/nginx/目录下
启动nginx服务
systemctl start nginx
关闭nginx服务
systemctl stop nginx
配置文件在/etc/nginx/nginx.conf，修改完后
systemctl reload nginx
4.2、官网下载
下载1.25.1
wget http://nginx.org/download/nginx-1.25.1.tar.gz
解压
tar -zxf nginx-1.25.1.tar.gz
检查配置，可能会缺少error: the HTTP rewrite module requires the PCRE library
.configure --- 缺少执行 apt-get install libpcre3 libpcre3-dev
编译
make&&make install
/usr/local/nginx/conf目录配置
执行启动停止操作需要进入/usr/local/nginx/sbin目录
./nginx 启动 Nginx
./nginx -s stop 停止 Nginx
./nginx -s reload 重新加载 Nginx
./nginx -v 查看 Nginx 版本
5、代理服务器
1、相关地址
- 主页 lanproxy.thingsglobal.org
- lanproxy-go-client github.com/ffay/lanpro…
- 发布包下载地址 github.com/ffay/lanpro…
2、上传
上传proxy-client-0.1.rar或者zip包，需要解压，安装unrar软件或者unzip
apt-get install unrar
或者
apt-get install unzip
然后解压
unrar x proxy-client-0.1.rar
或者
unzip proxy-client-0.1.rar
进入bin目录下，执行startup.sh文件，先给文件添加执行权限，再执行
laibin@iZ7xvcns9k722thqiufsvnZ:~/proxy-server-0.1/bin$ chmod +x startup.sh
laibin@iZ7xvcns9k722thqiufsvnZ:~/proxy-server-0.1/bin$ ./startup.sh
Starting the proxy server ...started
PID: 9659
接下来输入ip:端口输入设置的用户名密码即可访问。
端口开放可以去阿里云的云服务控制台的安全组中开放。
