CentOS6 安装couchdb2 集群

参考：http://blog.csdn.net/wh211212/article/details/74359497 安装节点

安装couchdb2 节点二

参考安装节点一，使用一键安装脚本进行节点二的安装

配置集群

修改node1 和node2 hosts配置

# n1couchdb.aniu.so127.0.0.1   localhost localhost.localdomain n1couchdb.aniu.so192.168.0.154 n1couchdb.aniu.so192.168.0.155 n2couchdb.aniu.so# n2couchdb.aniu.so127.0.0.1   localhost localhost.localdomain n2couchdb.aniu.so192.168.0.154 n1couchdb.aniu.so192.168.0.155 n2couchdb.aniu.so

登录web界面配置

• http://n1couchdb.aniu.so:5984/_utils/#setup

• 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:[e-mail]:5984/_membership{"all_nodes":["[e-mail]","[e-mail]"],"cluster_nodes":["[e-mail]","[e-mail]"]}curl http://admin:[e-mail]: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

• http://192.168.0.155:5984/_membership

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.crtkey_file = /etc/couchdb/server.key
