查看ubuntu版本名

lsb_release -c

备份原来的软件源

sudo cp -v /etc/apt/sources.list /etc/apt/sources.list.backup

执行chmod命令更改文件权限使软件源文件可编辑

sudo chmod 777 /etc/apt/sources.list

2.1 go

https://golang.google.cn/doc/install

2.1.1 建立软件目录并安装软件

tar zxvf go1.20.2.linux-amd64.tar.gz -C /usr/local/app

2.1.2 建立go工作目录

mkdir /usr/local/gopro

2.1.3 配置环境变量

gedit /etc/profile

export GO_ROOT=/usr/local/app/go
export GOPATH=/usr/local/gopro
export GOPROXY=https://goproxy.cn  #代理
export PATH=$PATH:$GO_ROOT/bin

2.2 mysql

2.2.1 安装

sudo apt-get install -y mysql-server

2.2.2 建立对外用户并更改密码

sudo cat /etc/mysql/debian.cnf
# 登录 mysql
mysql -u debian-sys-maint -p
# 修改 root 密码
use mysql;
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';

# 建立用户wyt，密码wyt，并授权
CREATE USER 'wyt'@'%' IDENTIFIED BY 'wyt';
GRANT ALL PRIVILEGES ON *.* TO 'wyt'@'%';
FLUSH PRIVILEGES;

2.2.3 修改配置文件运行远程链接

# 修改 mysql 配置文件
sudo gedit /etc/mysql/mysql.conf.d/mysqld.cnf
#bind-address           = 127.0.0.1
#mysqlx-bind-address    = 127.0.0.1

2.3 redis

select 0
keys *
set amy 10  # 赋值
get amy  # 取值
del amy  # 删除
