CRS-0184: Cannot communicate with the CRS daemon

今天不小心重新启动了机器，导致用vmware做的2node redhat  4AS的 其中一起机器重启后运行crs_stat -t时出现

CRS-0184: Cannot communicate with the CRS daemon错误。

使用$ORA_CRS_HOME/bin/crsctl stop crs和$ORA_CRS_HOME/bin/crsctl start crs后，仍然不起作用，查看$ORA_CRS_HOME/log/rac1/crsd/crsd.log发现：

后到上搜索了一下，还真有解决办法：

the reason why it was unable to start was that each time  reboots it creates a socket at /tmp/.oracle or /var/tmp/.oracle directory .

Also if there are previously existing sockets they cannot be reused or deleted automatically from this directory .oracle.

Therefore the solution to above problem was obtained by deleting all the files ins

the reason why it was unable to start was that each time server reboots it creates a socket at /tmp/.oracle or /var/tmp/.oracle directory .

Also if there are previously existing sockets they cannot be reused or deleted automatically from this directory .oracle.

Therefore the solution to above problem was obtained by deleting all the files inside .oracle directoery in /var/tmp or /tmp.

ide .oracle directoery in /var/tmp or /tmp.

然后重新启动机器就可以了。

问题解决了，
删除node1机器上的/etc/oracle/scls_scr/rac1/oracle/cssfatal 文件
如果不删这个文件，运行root.sh 脚本时会报错。
然后重新运行下$ORA_CRS_HOME/root.sh脚本
