1、把/ssd/oracle/u01/app/oraInventory下的全部清空
2、设置CV_ASSUME_DISTID
由于在该版本的cvu_prereq.xml文件中只是写了oel支持,现在的操作系统是Kylin，不在他的列表里面，所以需要在.bash_profile中添加export CV_ASSUME_DISTID=RHEL7.6
3、ar 和 as 两个二进制, Oracle使用的是绝对路径，使用 ln 绕过，解决方法：
mkdir -p /opt/rh/devtoolset-8/root/usr/bin/
ln -s /bin/ar /opt/rh/devtoolset-8/root/usr/bin/ar
ln -s /bin/as /opt/rh/devtoolset-8/root/usr/bin/as
也有这种说法，但是么有成功，无法下载：由于缺少了/opt/rh/devtoolset-8/root/usr/bin/ar程序导致,对其进行安装然后重试编译
4、dbca无法正常启动，静默方式直接退出，选择命令方式创建库
Exception in thread "main"
java.lang.UnsatisfiedLinkError: oracle.ops.mgmt.nativesystem.Native.getEnvironment(Ljava/lang/String;Loracle/ops/mgmt/nativesystem/NativeResult;)V
进入$ORACLE_HOME/dbs目录
orapwd file=orapwCDB password=cdb19c*- ignorecase=no
cp init.ora initCDB.ora
修改 initCDB.ora文件如下：
db_name='CDB'
memory_target=10G
processes = 1024
audit_file_dest='/ssd/oracle/u01/app/oracle/admin/CDB/adump'
audit_trail ='db'
db_block_size=8192
db_domain='oracle.com'
db_recovery_file_dest='/ssd/oracle/u01/app/oracle/fast_recovery_area'
db_recovery_file_dest_size=2G
diagnostic_dest='/ssd/oracle/u01/app/oracle'
#dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
# You may want to ensure that control files are created on separate physical
# devices
control_files = ('/ssd/oracle/u01/app/oracle/oradata/CDB/disk1/cdb_control1', '/ssd/oracle/u01/app/oracle/oradata/CDB/disk2/cdb_control2')
compatible ='19.3.0'
sqlplus / as sysdba
create spfile from pfile;
startup nomount;
@/home/oracle/dbcreate.sql
其中，dbcreate.sql建库命令：

好友安装时遇到的错误及解决方法：
1、报错1：$ORACLE_HOME/perl/bin/perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
使用ldd命令查看发现libnsl.so.1 => not found，安装库包dnf install libnsl解决。
2、报错2：PRVG-0282：failed to retrieve the operating system distribution ID
通过export CV_ASSUME_DISTID=RHEL7.6解决。
3、报错3:Error in invoking target 'libasmclntsh19.ohso libasmperl19.ohso client_sharedlib' of makefile
查看详细日志提示缺少libc_nonshared.a、libpthread_nonshared.a文件，从centos7.6上拷贝到麒麟/usr/lib64目录下解决。
