問(wèn)題解答

首先不能用root用戶登陸，sudo默認(rèn)就是root用戶，sudo時(shí)需要指定其他用戶名。例如：sudo -iu user_a bin/elasticsearch

新增了一個(gè)用戶，讓后在以新增用戶啟動(dòng)完成。不知道各路大神有沒(méi)有在root下啟動(dòng)的方法？

vi /etc/sysconfig/elasticsearch將 JAVA_HOME=/root/jdk1.8.0_60 寫到文件中保存后啟動(dòng)service elasticsearch start正在啟動(dòng) elasticsearch： [確定]

3樓正解，我以root用戶啟動(dòng)了

@geekfranca 我的Logstash是2.2.2版本，系統(tǒng)環(huán)境是ubuntu kylin 16，然后從[官網(wǎng)]下載的logstash_2.2.2-1_all.deb文件進(jìn)行安裝的，使用的是普通用戶，執(zhí)行sudo service logstash configtest時(shí)，提示如下：

Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME.

安裝@geekfranca 說(shuō)的方法，修改了/etc/init.d/logstash 文件，執(zhí)行成功了，道理應(yīng)該都是一樣的
