2. 驗證需要的rpm包
rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXext libXtst libX11 libXau libxcb libXi make sysstat
查詢結果
binutils-2.27-27.base.el7.x86_64 compat-libcap1-1.10-7.el7.x86_64 package compat-libstdc++-33 is not installed gcc-4.8.5-28.el7.x86_64 gcc-c++-4.8.5-28.el7.x86_64 glibc-2.17-222.el7.x86_64 glibc-devel-2.17-222.el7.x86_64 package ksh is not installed libaio-0.3.109-13.el7.x86_64 package libaio-devel is not installed libgcc-4.8.5-28.el7.x86_64 libstdc++-4.8.5-28.el7.x86_64 libstdc++-devel-4.8.5-28.el7.x86_64 libXext-1.3.3-3.el7.x86_64 libXtst-1.2.3-1.el7.x86_64 libX11-1.6.5-1.el7.x86_64 libXau-1.0.8-2.1.el7.x86_64 libxcb-1.12-1.el7.x86_64 libXi-1.7.9-1.el7.x86_64 make-3.82-23.el7.x86_64 sysstat-10.1.5-13.el7.x86_64
安裝沒有安裝的仨個包
yum install -y compat-libstdc++-33 yum install -y libaio-devel
yum install -y ksh
3. 修改 系統配置
vi /etc/sysctl.conf 添加或修改下面參數 kernel.shmmax = 68719476736 kernel.shmall = 106029312 kernel.shmmni = 4096 kernel.sem =250 32000 100 128 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1262144 net.ipv4.ip_local_port_range =9000 65500 fs.file-max=7065536 fs.aio-max-nr=1048576
修改
/etc/security/limits.conf
內容中添加如下配置。
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240 oracle hard stack 10240
關閉防火牆 關閉selinux
添加用戶
groupadd oinstall groupadd dba useradd -g oinstall -G dba oracle 修改密碼 passwd oracle 創建oracle主目錄 mkdir -p /u01/oracle 修改目錄權限 chown -R oracle:oinstall /u01/oracle chmod -R 775 /u01/oracle
修改環境變量. 在/etc/profile.d目錄下新增一個oracle.sh 增加內容為
ORACLE_BASE=/u01/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/18.3.0/db_1; export ORACLE_HOME ORACLE_SID=ora18c; export ORACLE_SID ORACLE_TERM=xterm; export ORACLE_TERM PATH=/usr/sbin:$PATH; export PATH PATH=$ORACLE_HOME/bin:$PATH; export PATH LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi
重新登錄 驗證 環境變量正常
echo $ORACLE_HOME
echo $ORACLE_SID
4. 上傳linux 的安裝包文件
xftp或者其他方式
解壓縮 修改 安裝權限
修改host 關閉防火牆 關閉 selinux 等步驟不在復述
5. 進入 GUI 圖形化安裝
注意 18c 與之前的不一樣 需要將 安裝文件放到 oracle_home 路徑下來執行安裝 沒有再選擇 oracle_home的選項了
mkdir -p $ORACLE_HOME
mv -R * $ORACLE_HOME
6. dbca 建庫
tips 本次安裝與其他的區別
注意加黑與紅色字體部分
這次安裝失敗了三次 才想到官網找解決方案.
1. 下載地址 http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html 2. 本次安裝應用端的速度很快好像更改了部分地方 官網地址: https://docs.oracle.com/en/database/oracle/oracle-database/18/ladbi/running-oracle-universal-installer-to-install-oracle-database.html#GUID-DD4800E9-C651-4B08-A6AC-E5ECCC6512B9 1. Log in as the Oracle installation owner user account (oracle) that you want to own the software binaries. Download the Oracle Database installation image files (db_home.zip) to a directory of your choice. For example, you can download the image files to the /tmp directory. Create the Oracle home directory and extract the image files that you have downloaded in to this Oracle home directory. For example: $ mkdir -p /u01/app/oracle/product/18.0.0/dbhome_1 $ chgrp oinstall /u01/app/oracle/product/18.0.0/dbhome_1 $ cd /u01/app/oracle/product/18.0.0/dbhome_1 $ unzip -q /tmp/db_home.zip Note: 2. Oracle recommends that the Oracle home directory path you create is in compliance with the Oracle Optimal Flexible Architecture recommendations. Also, unzip the installation image files only in this Oracle home directory that you created. From the Oracle home directory, run the runInstaller command to start the Oracle Database Setup Wizard. $ cd /u01/app/oracle/product/18.0.0/dbhome_1 $ ./runInstaller Note: Run the runInstaller command from the Oracle home directory only. Do not run runInstaller from any other location. 3. In the Select Configuration Option screen, select Create and configure a single instance database. 4.Select your installation type. Installation screens vary depending on the installation option you select. Respond to the configuration prompts as needed. Note: Click Help if you have any questions about the information you are asked to submit during installation.
