### 下载安装conda
下载地址：https://docs.conda.io/en/latest/
笔者下载的是`Miniconda3-latest-Linux-x86_64.sh`
安装：
```shell
bash Miniconda3-latest-Linux-x86_64.sh -b -p /home/software/miniconda3
# -p 可指定安装目录
# 安装后添加conde到 环境变量PATH中
export PATH=/home/software/miniconda3/bin/$PATH
# 执行初始化
conda init
```
### 创建环境报错
错误信息：
```shell
[root@localhost software]# conda create -n langchain python=3.9
Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate is not yet valid (_ssl.c:1032)'))': /pkgs/main/terms.json
```
错误原因：系统时间不正确
修改并同步时间：
```shell
# 停止 chronyd
sudo systemctl stop chronyd
# 手动设置一个可靠的时间源（可选）
sudo timedatectl set-ntp true
# 编辑 chrony 配置，使用国内源（加快同步）
sudo tee /etc/chrony.conf <<EOF

keyfile /etc/chrony.keys
leapsectz right/UTC
logdir /var/log/chrony
EOF
# 重启 chronyd
sudo systemctl restart chronyd
# 强制立即同步
sudo chronyc makestep
# 等待几秒后检查

# 更新 ca-certificates 包
sudo dnf update -y ca-certificates
# 重建证书信任链
sudo update-ca-trust force-enable
sudo update-ca-trust extract
