11月 25 17:42:01 erlang systemd[1]: zookeeper.service failed.

处理思路：

1.首先我们打开报错的文件。

# vim /usr/local/kafka_2.13-3.0.0/bin/kafka-run-class.sh

2.使用:set nu显示行号，并找到报错的342行。

342   exec "$JAVA" $KAFKA_HEAP_OPTS $KAFKA_JVM_PERFORMANCE_OPTS $KAFKA_GC_LOG_OPTS $KAFKA_JMX_OPTS $KAFKA_LOG4J_OPTS -cp "$CLASSPATH" $KAFKA_OPTS "$@"

看到这里，最直观的联想就是没有找到java命令。

3.查看是否运行java

[root@erlang]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

明明是有java命令，并且/etc/profile中也已经配置了环境变量

export JAVA_HOME=/usr/local/jdk1.8.0_171
export CLASSPATH=$:CLASSPATH:$JAVA_HOME/lib/
export PATH=$PATH:$JAVA_HOME/bin

4.百度找到解决方法(但是无果)
原帖是这样写的：
大概猜到需要使用java命令，所以我们在配置文件中加入该环境变量。
于是照做，将我服务器的环境变量更改后如下：

 export JAVA_HOME=/usr/local/jdk1.8.0_171
 export JAVA=/usr/local/jdk1.8.0_171/bin/java
 export CLASSPATH=$:CLASSPATH:$JAVA_HOME/lib/
 export PATH=$PATH:$JAVA_HOME/bin

再次执行systemctl start zookeeper还是报相同的错误。

5.最终大招（解决问题）
将java的路径软链接到/usr/bin和/usr/sbin目录下

# ln -s export JAVA=/usr/local/jdk1.8.0_171/bin/java  /usr/bin/java
# ln -s export JAVA=/usr/local/jdk1.8.0_171/bin/java  /usr/sbin/java

再次执行systemctl start zookeeper，成功运行。

6.查看结果。
