无法在CentOS 6中启动cassandra: numactl: execution

Question

我试图用Datastax Apache Cassandra安装OpenJDK

# java -version
java version "1.7.0_51"
OpenJDK Runtime Environment (rhel-2.4.4.1.el6_5-x86_64 u51-b02)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

# mkdir -p /var/log/cassandra /var/lib/cassandra
# chown -R `whoami` /var/log/cassandra /var/lib/cassandra

# curl -L http://downloads.datastax.com/community/dsc.tar.gz | tar xz
# cd dsc-cassandra-2.*

当我在前台运行cassandra时，会得到以下错误：

# bin/cassandra -f
numactl: execution of `': No such file or directory

设置JAVA_HOME似乎也行不通：

# echo $JAVA_HOME
/usr/local/jdk

# JAVA_HOME=/usr/local/jdk bin/cassandra -f
numactl: execution of `': No such file or directory

Answer 1

请设置您的JAVA_HOME变量。这应该能解决这个问题。

Answer 2

追加PATH并设置JAVA_HOME变量如下所示。请参见在基于RHEL的系统这里上安装Oracle的步骤4.

export PATH="$PATH:/usr/java/latest/bin"
set JAVA_HOME=/usr/java/latest
