RPM 安装oracle18c 修改字符集的方法

1. 安装完preinstall 和 oracle 的rpm版本之后 到这个界面

rpm -ivh oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm 
warning: oracle-database-preinstall-18c-1.0-1.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

[root@CentOS75 oracle18c]# rpm -ivh oracle-database-ee-18c-1.0-1.x86_64.rpm

[INFO] Oracle home installed successfully and ready to be configured.
To configure a sample Oracle Database you can execute the following service configuration script as root: /etc/init.d/oracledb_ORCLCDB-18c configure

2. 修改一下文件

cd /etc/init.d/
vim oracledb_ORCLCDB-18c 

修改如图：

export ORACLE_HOME=/opt/oracle/product/18c/dbhome_1

export ORACLE_VERSION=18c
export ORACLE_SID=ORA18CRPMCDB
export TEMPLATE_NAME=General_Purpose.dbc
export CHARSET=ZHS16GBK
export PDB_NAME=ORA18CRPMPDB
export LISTENER_NAME=LISTENER
export NUMBER_OF_PDBS=1
export CREATE_AS_CDB=true

# General exports and vars
export PATH=$ORACLE_HOME/bin:$PATH
LSNR=$ORACLE_HOME/bin/lsnrctl
SQLPLUS=$ORACLE_HOME/bin/sqlplus
DBCA=$ORACLE_HOME/bin/dbca
ORACLE_OWNER=oracle
RETVAL=0
CONFIG_NAME="oracledb_$ORACLE_SID-$ORACLE_VERSION.conf"
CONFIGURATION="/etc/sysconfig/$CONFIG_NAME"

3. 增加相应的配置文件

cd /etc/sysconfig/

复制配置文件

cp oracledb_ORCLCDB-18c.conf oracledb_ORA18CRPMCDB-18c.conf

4. 进行配置

使用root 用户执行命令

/etc/init.d/oracledb_ORCLCDB-18c configure

5. 配置安装完成

[root@CentOS75 sysconfig]# /etc/init.d/oracledb_ORCLCDB-18c configure
Configuring Oracle Database ORA18CRPMCDB.
