第1步：将CouchDB存储库添加到Ubuntu

将Apache CouchDB存储库添加到Ubuntu方面很简单。

运行以下命令以添加存储库密钥和存储库。

sudo apt install curl
curl -L https://couchdb.apache.org/repo/bintray-pubkey.asc | sudo apt-key add 
echo "deb https://apache.bintray.com/couchdb-deb focal main" | sudo tee -a /etc/apt/sources.list

第3步：访问Apache CouchDB

安装CouchDB后，默认端口号是5984，
可以使用浏览器打开

http://127.0.0.1:5984/_utils/

输入管理员用户名和密码。

第2步：更新并安装Apache CouchDB

运行以下命令以更新并安装最新的Apache CouchDB包

sudo apt update
sudo apt-get install apache2 couchdb

在安装过程中，您应该看到一些选择选项的消息。

安装couchdb之后，下面的命令可用于停止，启动，启用和检查其状态。

sudo systemctl stop couchdb.service
sudo systemctl start couchdb.service
sudo systemctl enable couchdb.service
sudo systemctl status couchdb.service
