環境：Redhat Linux 7.6 + Oracle 11.2.0.4 RAC
現象：圖像化安裝過程中，按照提示執行root.sh腳本，報錯中斷。
1. 具體現象
[root@mm1903 ~]# /u01/app/11.2.0/grid/root.sh Performing root user operation for Oracle 11g The following environment variables are set as: ORACLE_OWNER= grid ORACLE_HOME= /u01/app/11.2.0/grid Enter the full pathname of the local bin directory: [/usr/local/bin]: The contents of "dbhome" have not changed. No need to overwrite. The contents of "oraenv" have not changed. No need to overwrite. The contents of "coraenv" have not changed. No need to overwrite. Entries will be added to the /etc/oratab file as needed by Database Configuration Assistant when a database is created Finished running generic part of root script. Now product-specific root actions will be performed. Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params User ignored Prerequisites during installation Installing Trace File Analyzer Adding Clusterware entries to inittab ohasd failed to start Failed to start the Clusterware. Last 20 lines of the alert log follow: 2020-03-20 11:46:34.715: [client(14293)]CRS-2101:The OLR was formatted using version 3. 2020-03-20 11:57:25.130: [ohasd(15204)]CRS-0715:Oracle High Availability Service has timed out waiting for init.ohasd to be started. /u01/app/11.2.0/grid/perl/bin/perl -I/u01/app/11.2.0/grid/perl/lib -I/u01/app/11.2.0/grid/crs/install /u01/app/11.2.0/grid/crs/install/rootcrs.pl execution failed [root@mm1903 ~]#
Redhat 7.6搭建11g RAC時遇到報錯：
[ohasd(15204)]CRS-0715:Oracle High Availability Service has timed out waiting for init.ohasd to be started.
2. 定位問題
官方文檔：
Install of Clusterware fails while running root.sh on OL7 - ohasd fails to start (Doc ID 1959008.1)
由此篇官方文檔可知，致使root.sh腳本執行時報的原因是因為Linux 7與Linux 6啟動/重新啟動進程並將其作為服務運行的方式不同。
Linux 6是由initd啟動進程，而Linux 7則是由systemd啟動進程。
在11.2.0.4 & 12.1.0.1安裝GI時，無法加載集群資源進程，所以不會成功。
若想要在Linux 7上運行此兩個版本GI軟件，需要應用補丁程序18370031。
Because Oracle Linux 7 (and Redhat 7) use systemd rather than initd for starting/restarting processes and runs them as a service the current software install of both 11.2.0.4 & 12.1.0.1 will not succeed because the ohasd process does not start properly. In OL7 it needs to be set up as a service and patch fix for Bug 18370031 needs to be applied for this , BEFORE you run root.sh when prompted .
3. 解決問題
此外還有中簡單有效的解決方法，也是永久性的：
修改ohasd守護進程文件 vi /etc/init.d/ohasd 在文件中找到如這部分，在里面添加標注部分： ———————————————— if [ -r $AUTOSTARTFILE ] then case `$CAT $AUTOSTARTFILE` in enable*) $LOGERR "Oracle HA daemon is enabled for autostart." /bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1 & ---標注 my_crsctl start has -nowait sleep 600 ---標注 ps -ef | grep dd| grep hasd|awk '{print $2}'|xargs kill -9 ---標注 ;; disable*) $LOGERR "Oracle HA daemon is disabled for autostart." ;; *) $LOGERR "Oracle HA daemon is disabled by damaged install." $LOGERR "Unexpected settings found in $AUTOSTARTFILE." ;; esac else ————————————————
服務器再次重啟后，稍等片刻集群即會正常啟動。
正常加載日志：
