su - grid
解压 GRID 到 GRID用户的$ORACLE_HOME下
[grid@db40 grid]$ pwd/u01/app/18.3.0/grid[grid@db40 grid]$ unzip /tmp/LINUX.X64_180000_grid_home.zip 在自己的Windows系统上成功安装Xmanager Enterprise之后，运行Xstart.exe可执行程序，
配置如下
Session：db40
Host：192.168.1.40
Protocol：SSH
User Name：grid
Execution Command：/usr/bin/xterm -ls -display $DISPLAY
点击RUN，输入grid用户的密码可以正常弹出命令窗口界面，即配置成功。
当然也可以通过开启Xmanager - Passive，直接在SecureCRT连接的会话窗口中临时配置DISPLAY变量直接调用图形：
export DISPLAY=192.168.1.31:0.0
vi /etc/udev/rules.d/12-dm-permissions.rules
# MULTIPATH DEVICES## Set permissions for all multipath devicesENV{DM_UUID}=="mpath-?*", OWNER:="grid", GROUP:="asmadmin", MODE:="660"配置重载生效：
# udevadm control --reload# udevadm triggerXmanager通过grid用户登录，进入$ORACLE_HOME目录，运行gridSetup配置GI
$ cd $ORACLE_HOME$ ./gridSetup.sh其实从12cR2开始，GI的配置就跟之前有一些变化，18c也一样，下面来看下GI配置的整个图形化安装的过程截图：
注：这里Public网卡这里用的enp0s3，ASM&Private这里用的enp0s8，enp0s9和enp0s10是模拟IPSAN用到的网卡，所以这里不使用它们。
注：这里跟之前区别不大，我依然是选择3块1G的盘，Normal冗余作为OCR和voting disk。
注：这里有一个新的存储GIMR的，我这里选择是外部冗余的一个40G大小的盘，这是12c新引入的概念，18c依然如此。
注：这里检查出来的问题都需要认真核对，确认确实可以忽略才可以点击“Ignore All”，如果这里检测出缺少某些RPM包，需要使用yum安装好。
注：执行root脚本，确保先在一节点执行完毕后，再在其他节点执行。
第一个节点root执行脚本：

这段时间也很漫长，看来Oracle集群软件是越来越庞大了，老DBA们此时此刻有没有怀念11g甚至10g的时代呢？
安装过程中可以跟踪安装日志：
tail -20f /tmp/GridSetupActions2018-08-03_11-27-06PM/gridSetupActions2018-08-03_11-27-06PM.log注：日志中可以看到有一个阶段starting read loop消耗了1个多小时才进入到下个阶段，这很可能是有异常导致时间过长，但即使排除这个异常时间段依然还有将近2小时的时间。
INFO: [Aug 4, 2018 2:04:42 PM] ... GenericInternalPlugIn: starting read loop.INFO: [Aug 4, 2018 3:25:37 PM] Completed Plugin named: mgmtca
注：最后这个报错提示，查看日志发现是因为使用了一个scan ip的提示，可以忽略。
至此GI配置完成。
crsctl stat res -t查看集群资源状态信息，看到18c又新出现一些资源了，看来DBA又有新东西需要学习了~
