Oracle19c安装图文教程
一、安装前环境配置
1.基本信息
| OS | DB | HostName | DB Name | IP |
|---|---|---|---|---|
| oracle linux 7.7 | Oracle 19C | STUDY | win | 192.168.2.98 |
2.配置/etc/hosts
[root@STUDY /]# echo '192.168.2.98 STUDY' >> /etc/hosts
3.关闭防火墙和Selinux
[root@STUDY etc]# systemctl stop firewalld.service
[root@STUDY etc]# systemctl disable firewalld.service
[root@STUDY etc]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
4.配置系统参数
[root@STUDY etc]# vi /etc/sysctl.conf
添加如下内容：
kernel.shmmni=4096
kernel.sem=250 32000 100 128
fs.file-max=6815744
fs.aio-max-nr=1048576
net.ipv4.ip_local_port_range=9000 65500
net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048576
kernel.shmmax=53687091200
kernel.shmall=52780232
[root@STUDY etc]# vi /etc/pam.d/login
添加如下内容：
session required /lib64/security/pam_limits.so
session required pam_limits.so
[root@STUDY etc]# vi /etc/security/limits.conf
添加如下内容：
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
说明：
生产环境注意这两个参数，需要根据服务器的内存大小调整
kernel.shmmax：内核共享内存段最大值
kernel.shmall：所有内存（单位是页 4096）
[root@STUDY etc]#sysctl -p --使上面参数生效
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
kernel.shmmax = 53687091200
kernel.shmall = 52780232
5.创建用户oracle用户和组
[root@STUDY etc]# groupadd oinstall
[root@STUDY etc]# groupadd dba
[root@STUDY etc]# groupadd oper
[root@STUDY etc]# useradd -g oinstall -G dba,oper oracle
[root@STUDY etc]# passwd oracle
Changing password for user oracle.
New password:
BAD PASSWORD: The password fails the dictionary check - it is too simplistic/systematic
Retype new password:
passwd: all authentication tokens updated successfully.
[root@STUDY etc]# id oracle
uid=1000(oracle) gid=1000(oinstall) groups=1000(oinstall),1001(dba),1002(oper)
6.创建安装目录
[root@STUDY etc]# mkdir -p /u01/app/oracle/product/19.3/dbhome_1
[root@STUDY etc]# chown -R oracle:oinstall /u01/app
[root@STUDY etc]# chmod -R 775 /u01/app
7.配置yum
[root@STUDY etc]# cd /etc/yum.repos.d
[root@STUDY etc]# vi local-oraclelinux.repo
8.配置oracle 用户环境变量
[root@STUDY etc]# su – oracle
[oraclet@STUDY ~]$ vi /home/oracle/.bash_profile
添加如下内容：
umask 022
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/19.3/dbhome_1
ORACLE_SID=win
PATH= P A T H : PATH: PATH:HOME/.local/bin: H O M E / b i n : HOME/bin: HOME/bin:ORACLE_HOME/bin
export PATH ORACLE_BASE ORACLE_HOME ORACLE_SID
[oracle@STUDY ~]$ source /home/oracle/.bash_profile
9.服务器上VNC安装与配置
#yum -y install tigervnc-server-1.8.0-17.el7.x86_64.rpm
# vi /etc/sysconfig/vncservers
添加：
VNCSERVERS=“1:root”
VNCSERVERARGS[2]=“-geometry 800x600 -nolisten tcp -localhost”
[root@STUDY sysconfig]# vncserver --启动vnc服务
You will require a password to access your desktops.
Password:
Verify:
Would you like to enter a view-only password (y/n)? y
Password:
Verify:
xauth: file /root/.Xauthority does not exist
New 'STUDY:1 (root)' desktop is STUDY:1
Creating default startup script /root/.vnc/xstartup
Creating default config /root/.vnc/config
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/STUDY:1.log
[root@STUDY sysconfig]# service vncserver status --查看服务开启状态
Redirecting to /bin/systemctl status vncserver.service
Unit vncserver.service could not be found.
# vi /root/.vnc/xstartup --修改配置文件，激活图形界面
注释掉倒数三行，并在末尾 增加：
gnome-session &
[root@STUDY sysconfig]# xhost +
xhost: unable to open display ""
[root@STUDY sysconfig]# export DISPLAY=192.168.2.98:1.0
[root@STUDY sysconfig]# xhost +
access control disabled, clients can connect from any host
[root@STUDY dbhome_1]# su - oracle
[oracle@STUDY dbhome_1]$ export LANG=en_US --避免安装界面是中文时出现乱码
二、安装数据库软件
1.数据库软件准备
[root@STUDY etc]# mkdir /u01/app/soft
--已将数据库软件上传到/u01/app/soft
[root@STUDY etc]# chown oracle:oinstall /u01/app/soft/LINUX.X64_193000_db_home.zip
[root@STUDY etc]$ su - oracle
[oracle@STUDY ~]$ cd /u01/app/soft
[oracle@STUDY soft]$ unzip LINUX.X64_193000_db_home.zip -d /u01/app/oracle/product/19.3/dbhome_1 --解压到$ORACLE_HOME目录
2.数据库软件安装
[oracle@STUDY dbhome_1]$ ./runInstaller
安装过程记录如下：
[root@STUDY soft]# yum -y install libaio-devel-0.3.109-13.el7.x86_64.rpm
[root@STUDY soft]# yum -y install smartmontools-7.0-1.el7.x86_64.rpm
[root@STUDY soft]# yum -y install ksh-20120801-139.0.1.el7.x86_64.rpm
ksh包可以忽略
3.创建数据库
[oracle@STUDY ~]$ dbca
[oracle@STUDY dbhome_1]$ ps -ef|grep smon
oracle 109287 1 0 18:18 ? 00:00:00 ora_smon_win
