为什么弹性搜索不会在Ubuntu 14.04上运行？ [英] why elasticsearch won't run on Ubuntu 14.04?

问题描述

我正在尝试确定弹性搜索实例是否正在运行，但它似乎不是：

I'm trying to determine if the elasticsearch instance is running, but it doesn't appear to be:

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

和

ubuntu@ubuntu:/etc/elasticsearch$ sudo netstat -nlp
tcp6       0      0 :::9300                 :::*                    LISTEN      4413/java       

UPD

我的elasticsearch.log：

My elasticsearch.log:

推荐答案

Elasticsearch服务初始化脚本不会在控制台或日志上打印任何错误信息文件，当它无法启动，而不是可笑地显示 [OK] 。

Elasticsearch service init script doesn't print any error information on console or log file when it fails to startup, instead it ridiculously shows [OK].

你必须手动运行elaticsearch相同的用户和与init脚本相同的参数来检查出了什么问题。

You have to run elaticsearch manually with the same user and same parameters as what the init script does to check what's going wrong. The error message will be printed on console.

在我的Ubuntu 14.10中安装了elasticsearch-1.4.1.deb，没有任何路径更改，运行弹性搜索的命令是：

On my Ubuntu 14.10 with elasticsearch-1.4.1.deb installed, without any path changed, the command to run elastisearch is:

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

我刚刚在 /etc/init.d/elasticsearch 中添加了一行，以打印出以上命令：

I just added a line into /etc/init.d/elasticsearch to print out the above command:

# 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 $?
