Oracle Enterprise Manager Error - NMO setuid (root)
提问by user3041770
I've been trying for days to fix the "Connection to host as user SYSDBA failed.ERROR: NMO not setuid-root (Unix-only)".
几天来我一直在尝试修复“以用户 SYSDBA 身份连接到主机失败。错误：NMO not setuid-root（仅限 Unix）”。
All, without exception, of the blogs I visited, say that in order to fix the issue, it's only needed to run the root.sh script as root, where script path is $ORACLE_HOME. I did that during Oracle Grid and Database install as requested, but re-run to make sure.
无一例外，我访问过的所有博客都说，为了解决这个问题，只需要以 root 身份运行 root.sh 脚本，其中脚本路径是 $ORACLE_HOME。我按照要求在 Oracle Grid 和 Database 安装期间这样做了，但重新运行以确保。
If i list the permissions of nmo and nmb binary files after running the root.sh, i get:
如果我在运行 root.sh 后列出 nmo 和 nmb 二进制文件的权限，我会得到：
ls -la ./nm? -rws--x--- 1 root oinstall 34166 Apr 16 02:10 ./nmb -rws--x--- 1 root oinstall 44437 Apr 16 02:05 ./nmo
ls -la ./nm? -rws--x--- 1 root oinstall 34166 Apr 16 02:10 ./nmb -rws--x--- 1 root oinstall 44437 Apr 16 02:05 ./nmo
After following tutorials, i did: chown root nmo chmod 6750 nmo chown root nmb chmmod 6750 nmb
按照教程之后，我做了： chown root nmo chmod 6750 nmo chown root nmb chmmod 6750 nmb
permissions went like so:
权限是这样的：
ls -la ./nm? -rwsr-s--- 1 root oinstall 34166 Apr 16 02:10 ./nmb -rwsr-s--- 1 root oinstall 44437 Apr 16 02:05 ./nmo
ls -la ./nm? -rwsr-s--- 1 root oinstall 34166 Apr 16 02:10 ./nmb -rwsr-s--- 1 root oinstall 44437 Apr 16 02:05 ./nmo
Above permissions are according to what most blogs said they should be like. SO I relaunched EM:
以上权限是根据大多数博客所说的。所以我重新启动了 EM：
emctl stop dbconsole emctl start dbconsole
emctl 停止 dbconsole emctl 启动 dbconsole
and Still got the error. I am almost performing a fresh install of Grid and Database, because I repeated the procedures multiple times, backed up /etc/oratab, deleted it and re run root.sh (so it could recreate oratab and fix possible mistakes).
仍然有错误。我几乎正在执行网格和数据库的全新安装，因为我多次重复这些过程，备份 /etc/oratab，将其删除并重新运行 root.sh（因此它可以重新创建 oratab 并修复可能的错误）。
I installed everything following the documentation, opened root.sh and referenced scripts so I could read them, but found nothing suspect.
我按照文档安装了所有内容，打开了 root.sh 并引用了脚本，以便我可以阅读它们，但没有发现任何可疑之处。
My EM version is 11.2.0.3.0
我的EM版本是11.2.0.3.0
I am running Oracle Linux under VirtualBox.
我在 VirtualBox 下运行 Oracle Linux。
AGAIN: I've executed the root.sh as suggested in 99% of the websites regarding the setuid nmo error... Any clues or different procedures?
再次：我已经按照 99% 的网站中关于 setuid nmo 错误的建议执行了 root.sh ......任何线索或不同的程序？
Thanks.
谢谢。

Check if the filesystem that $ORACLE_HOME is in, is mounted with the nosuidoption. If it is, that will prevent any executable running as root, even if SUID bit is set.
检查 $ORACLE_HOME 所在的文件系统是否使用该nosuid选项挂载。如果是，即使设置了 SUID 位，也会阻止任何以 root 身份运行的可执行文件。
Hope that helps.
希望有帮助。

Execute root.sh script in $ORACLE_HOME directory as root user:
以 root 用户身份在 $ORACLE_HOME 目录中执行 root.sh 脚本：
For example:
例如：
sh /opt/oracle/product/11g/root.sh
sh /opt/oracle/product/11g/root.sh

Beside root.sh. You might run into my case.
在 root.sh 旁边。你可能会遇到我的情况。
Got the similar problem and found out the error came from inadequate swap space. My swap is low and run down to 300MB, this problem "Failed to launch process: Cannot run program "/opt/OEMAgent/sbin/nmo" (in directory /opt/OEMAgent/agent_inst/bin"): error=12, Not enough space" suddenly shows up.
遇到了类似的问题，发现错误来自交换空间不足。我的交换很低，运行到 300MB，这个问题“无法启动进程：无法运行程序“/opt/OEMAgent/sbin/nmo”（在目录/opt/OEMAgent/agent_inst/bin 中）：错误=12，不是足够的空间”突然出现。
It goes away immediately after adding additional swap space.
添加额外的交换空间后，它会立即消失。
