linux - 无法以 root 用户身份启动 Oracle 监听器

Question

我想以 root 用户身份启动 Oracle Listner。我能够以 oracle 用户身份启动监听器。 但它不是以 root 用户身份启动的。 我能够以 root 用户身份停止并检查状态。

当我以 root 身份启动监听器时，它会给出以下消息:-

# lsnrctl start

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 08-MAY-2012 15:08:11

Starting /opt/oracle/102/bin/tnslsnr: please wait...

/opt/oracle/102/bin/tnslsnr: error while loading shared libraries: libclntsh.so.10.1: cannot open shared object file: No such file or directory
TNS-12547: TNS:lost contact
 TNS-12560: TNS:protocol adapter error
  TNS-00517: Lost contact
   Linux Error: 32: Broken pipe

请帮助我以 root 用户身份启动监听器。

您不应以 root 用户身份运行 Oracle，这是一种安全风险。没有理由以 root 用户身份运行 rdbms 和/或监听器，除非你完全搞砸了安装，否则甚至不允许以 root 用户身份运行。

如果您确实需要以 root 用户身份运行监听器，请确保您的环境变量是正确的。在你的情况下:

   # export ORACLE_HOME=/opt/oracle/102
   # export PATH=$PATH:$ORACLE_HOME/bin

   # cd $ORACLE_HOME/bin
   # chmod u+s lsnrctl
   # lsnrctl start

不要这样做；如果你这样做，你就错了。选择属于 dba 组但不是 root 的任何其他用户。

顺便说一句:在这个小演示之后我不得不解决一个小问题:

Started with pid=5215 Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))) TNS-12555: TNS:permission denied TNS-12560: TNS:protocol adapter error
TNS-00525: Insufficient privilege for operation Linux Error: 1: Operation not permitted

问题很明显 -/var/tmp/.oracle/sLISTENER 归 root 所有。对正确的用户稍加点赞就解决了这个问题。
