我正在尝试确定elasticsearch实例是否正在运行,但它似乎不是:
ubuntu@ubuntu:~$ sudo service elasticsearch status * elasticsearch is not running ubuntu@ubuntu:~$ sudo service elasticsearch start * Starting Elasticsearch Server [ OK ] ubuntu@ubuntu:~$ sudo service elasticsearch status * elasticsearch is not running and ubuntu@ubuntu:~$ sudo /etc/init.d/elasticsearch status * elasticsearch is not running ubuntu@ubuntu:~$ sudo /etc/init.d/elasticsearch start * Starting Elasticsearch Server [ OK ] ubuntu@ubuntu:~$ sudo /etc/init.d/elasticsearch status * elasticsearch is not running ubuntu@ubuntu:/etc/elasticsearch# sudo service elasticsearch restart * Stopping Elasticsearch Server [ OK ] * Starting Elasticsearch Server [ OK ] ubuntu@ubuntu:/etc/elasticsearch# sudo service elasticsearch status * elasticsearch is not running
和
ubuntu@ubuntu:~$ curl -XGET localhost:9200/_nodes/_all/process?pretty curl: (7) Failed to connect to localhost port 9200: Connection refused
ubuntu@ubuntu:/etc/elasticsearch$ sudo netstat -nlp tcp6 0 0 :::9300 :::* LISTEN 4413/java
UPD
我的elasticsearch.log:

当启动失败时,Elasticsearch服务初始化脚本不会在控制台或日志文件上显示任何错误信息,而是荒谬地显示[OK]。
[OK]
您必须使用与初始化脚本相同的用户和参数来手动运行elaticsearch,以检查出了什么问题。错误消息将打印在控制台上。
在安装了elasticsearch-1.4.1.deb的Ubuntu 14.10上,未更改任何路径,运行elastisearch的命令是:
sudo -u elasticsearch /usr/share/elasticsearch/bin/elasticsearch -d -p /var/run/elasticsearch.pid --default.config=/etc/elasticsearch/elasticsearch.yml --default.path.home=/usr/share/elasticsearch --default.path.logs=/var/log/elasticsearch --default.path.data=/var/lib/elasticsearch --default.path.work=/tmp/elasticsearch --default.path.conf=/etc/elasticsearch
我只是添加了一行/etc/init.d/elasticsearch以打印出上面的命令:
/etc/init.d/elasticsearch
# Start Daemon log_daemon_msg "sudo -u $ES_USER $DAEMON $DAEMON_OPTS" # <-- Add this line start-stop-daemon --start -b --user "$ES_USER" -c "$ES_USER" --pidfile "$PID_FILE" --exec $DAEMON -- $DAEMON_OPTS log_end_msg $?
