登錄oracle官網(wǎng)，搜索19c，點(diǎn)擊第一條

點(diǎn)擊左下角的ownload Database 19c

本文下載的是rpm版本

下載預(yù)安裝環(huán)境wget https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

執(zhí)行安裝命令sudo rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

顯示缺少依賴包

sudo yum install -y gcc-c++ make

sudo? yum install -y ksh

sudo yum install -y sysstat

sudo yum install libaio-devel

compat-libstdc++-33及compat-libcap1通過yum下載不到

百度搜索找到一個(gè)網(wǎng)址下載

http://mirror.centos.org/centos/7/os/x86_64/Packages/compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

http://mirror.centos.org/centos/7/os/x86_64/Packages/compat-libcap1-1.10-7.el7.x86_64.rpm

rpm -ivh?compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

rpm -ivh?compat-libcap1-1.10-7.el7.x86_64.rpm

ok，環(huán)境若還缺的朋友可以通過yum把配置補(bǔ)全

sudo rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

sudo rpm -ivh oracle-database-ee-19c-1.0-1.x86_64.rpm

sudo /etc/init.d/oracledb_ORCLCDB-19c configure

要等挺久的

netstat -nultp | grep -E '1521|5500'

ps -ef | grep -i orcl | grep -v grep

至此安裝完成。

安裝完后自然是連接

切換到root用戶

vim .bash_profile

加上export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1

export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/bin

export ORACLE_SID=ORCLCDB

切換到oracle用戶，執(zhí)行 sqlplus / as sysdba
