找不到python解释器。中止- Opscenter

Question

我只想问一下在我们的opscenter rpm上有什么可能性。启动opscenter时出现此错误

[opscenter@mybox]$ sudo /etc/init.d/opscenterd start
Starting Cassandra cluster manager opscenterd
Starting opscenterdNo python interpreter found. Abort.
[opscenter@mybox start-stop-scripts]$ cd            [FAILED]

我看到安装了python，但不确定如何使操作员将其指向此位置。

[opscenter@mybox ~]$ python -V ; which python
Python 2.7.1
/opt/mybox/pkg/python/bin/python

Opscenter安装在/opt/mybox/pkg/opscenter上，我在位于bin的opscenter文件中看到了一些变量

# get around sudo vagaries in setting $HOME
if [ "x$OPSC_HOME" = "x" ]; then
if [ $is_mac = 1 ]; then
    OPSC_HOME="/Users/$USER"
else
    OPSC_HOME=$(getent passwd $(id -u) | cut -d ':' -f 6)
fi
fi
export HOME=$OPSC_HOME

cd "$(dirname "$0")"/../

if [ $(uname -m) = "x86_64" ]; then

exit 3
}

不确定如何使操作者将其指向此位置

由于这是你的具体问题，我将在这里回应我的评论作为答案。

在运行opscenter init脚本之前，可以将PYTHON设置为python解释器。这将绕过对Python2.6或2.7的检查(通过-z测试)，并允许您只需告诉脚本python在哪里。

$ export PYTHON=/opt/mybox/pkg/python/bin/python
$ sudo /etc/init.d/opscenterd start

至于发生这种情况的根本原因，我怀疑PM 2Ring是正确的，python不在启动OpsCenter的用户(似乎是根用户)的路径上。
