- 对两个节点设置监听地址为0.0.0.0，管理员账号密码为 admin password，建议每个节点做同样的设置，避免出问题，然后，在窗体的下半部分，在“添加NODES”下，添加了另外一个节点。在远程主机中，键入n2couchdb.aniu.so，然后单击绿色的“添加节点”按钮。点击绿色的“配置群集”按钮完成。
查看集群节点：
curl http://admin:password@n1couchdb.aniu.so:5984/_membership
{"all_nodes":["couchdb@n1couchdb.aniu.so","couchdb@n2couchdb.aniu.so"],"cluster_nodes":["couchdb@n1couchdb.aniu.so","couchdb@n2couchdb.aniu.so"]}
curl http://admin:password@n2couchdb.aniu.so:5984/_membership
- 节点一
erl -sname bus -setcookie 'brumbrum' -kernel inet_dist_listen_min 9100 -kernel inet_dist_listen_max 9200
- 节点二
erl -sname bus -setcookie 'brumbrum' -kernel inet_dist_listen_min 9100 -kernel inet_dist_listen_max 9200
查看集群状态
配置couchdb daemon脚本
待更新
注意事项
建议不要直接修改/etc/couchdb/default.ini，因为default.ini会随着couchdb的更新而被覆盖，建议修改/etc/couchdb/local.ini
- 如果开启防火需要设置：
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 5984
配置使用证书
# cd /etc/couchdb
# openssl req -new -x509 -nodes -newkey rsa:4096 -keyout server.key -out server.crt
/etc/couchdb/local.ini
[daemons]
httpsd = {couch_httpd, start_link, [https]}
[ssl]
cert_file = /etc/couchdb/server.crt
key_file = /etc/couchdb/server.key
