couchdb.service：失败，结果为“ start-limit-hit”

Question

在安装了Sofadb之后，我可以获得欢迎信息

$ curl localhost:5984       
{"couchdb":"Welcome","version":"2.1.2","features":["scheduler"],"vendor":{"name":"The Apache Software Foundation"}}

但是我无法通过systemctl

查看状态

$ systemctl status  couchdb.service
● couchdb.service
   Loaded: not-found (Reason: No such file or directory)
   Active: failed (Result: start-limit-hit) since 一 2018-12-03 14:52:14 CST; 6min ago

当我通过命令行运行couchdb时，我得到了

$ couchdb 
{"init terminating in do_boot",{{badmatch,{error,{bad_return,{{couch_app,start,[normal,["/etc/couchdb/default.ini","/etc/couchdb/local.ini"]]},{'EXIT',{{badmatch,{error,{error,eacces}}},[{couch_server_sup,start_server,1,[{file,"couch_server_sup.erl"},{line,56}]},{application_master,start_it_old,4,[{file,"application_master.erl"},{line,273}]}]}}}}}},[{couch,start,0,[{file,"couch.erl"},{line,18}]},{init,start_it,1,[]},{init,start_em,1,[]}]}}
[1]    2288 user-defined signal 2  couchdb

我的工作环境

Answer 1

这有点晚，但是“ start-limit-hit”消息是一条红色鲱鱼。我已经看到使用MySQL安装Moodle的情况非常相似，实际上是在说您（或服务启动过程）在尝试启动失败后尝试太多次或太早地重新启动数据库。基本上，此开始-限制-命中信息是说“停止尝试做相同的事情并期待不同的结果”。

实际问题将在系统日志中进一步讨论。无助地，服务状态没有返回足够多的错误消息行以实际查看出什么问题。尝试启动服务，然后去查看实际的系统日志，您将看到一系列的启动尝试，并且每行上方都有一行希望可以告诉您实际的问题。在我的情况下，您可以看到问题是缺少包含数据库的安装点-谢谢，Azure。对于一次服务启动尝试，它尝试快速连续启动5次，每次都失败，因为未安装数据目录，而在第六次尝试失败，并显示start-limit-hit。

在升级CouchDB之前总是备份data /和etc /目录。

We recommend that you overwrite your etc/default.ini file with the version provided by the new release. New defaults sometimes contain mandatory changes to enable default functionality. Always places your customization in etc/local.ini or any etc/local.d/*.ini file.
