0. 查看操作系统版本
[root@12c01 ~]# cat /etc/os-release 微信PK10源码搭建 [企俄：2152876294] 网址diguaym.com
NAME="Oracle Linux Server" VERSION="6.8"
1. 修改用户的SHELL的限制，vi /etc/security/limits.conf 文件,文件末尾添加修改如下 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240
2. 修改linux内核，修改 /etc/sysctl.conf 文件 vi /etc/sysctl.conf 文件并添加如下内容： fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 4294967295 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 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 或者kernel.shmall和kernel.shmmax的默认值已经超过上述值，使用默认值即可。 修改生效 [root@12c01 ~]# /sbin/sysctl -p
3. 创建用户 /usr/sbin/groupadd -g 54321 oinstall /usr/sbin/groupadd -g 54322 dba /usr/sbin/groupadd -g 54323 oper /usr/sbin/groupadd -g 54324 backupdba /usr/sbin/groupadd -g 54325 dgdba /usr/sbin/groupadd -g 54326 kmdba /usr/sbin/groupadd -g 54327 asmdba /usr/sbin/groupadd -g 54328 asmoper /usr/sbin/groupadd -g 54329 asmadmin /usr/sbin/groupadd -g 54330 racdba /usr/sbin/useradd -u 54321 -g oinstall -G dba,asmdba,oper oracle /usr/sbin/useradd -u 54322 -g oinstall -G asmdba,asmadmin grid
4. 确认用户： [root@12c01 ~]# id oracle uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper),54327(asmdba) [root@12c01 ~]# id grid uid=54322(grid) gid=54321(oinstall) groups=54321(oinstall),54327(asmdba),54329(asmadmin)
5. 修改密码：让你输入密码，密码任意输入2次，但必须保持一致，回车确认 [root@12c01 ~]# passwd oracle Changing password for user oracle. New password: BAD PASSWORD: it is based on a dictionary word BAD PASSWORD: is too simple Retype new password: passwd: all authentication tokens updated successfully. [root@12c01 ~]# passwd grid Changing password for user grid. New password: BAD PASSWORD: it is too short BAD PASSWORD: is too simple Retype new password: passwd: all authentication tokens updated successfully.
6. 创建目录结构： mkdir -p /home/oracle/app/oracle/product/12.2.0/dbhome_1 mkdir -p /home/oracle/app/oradata chown -R oracle:oinstall /home/oracle/
7. 设置oracle用户的环境变量: #vi .bash_profile --将如下代码添加到.bash_profile文件中： # Oracle Settings umask 022 export TMP=/tmp; export TMPDIR=$TMP; export ORACLE_BASE=/home/oracle/app/oracle; export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/dbhome_1; export ORACLE_SID=andycdb; export ORACLE_TERM=xterm; export PATH=/usr/sbin:$PATH; export PATH=$ORACLE_HOME/bin:$PATH; export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;
8. 检查 /etc/hosts 文件确认是否添加主机名和域名全称 [root@12c01 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.100.25.16 12c01
9. 将Oracle安装包(以64位为例)复制到linux的home目录下，打开终端命令行界面，运行unzip命令解压oracle安装文件。 输入命令： [oracle@12c01 ~]$ ll total 3372760 drwxr-xr-x. 4 oracle oinstall 4096 May 6 03:31 app -rw-r--r--. 1 oracle oinstall 3453696911 May 6 03:38 linuxx64_12201_database.zip [oracle@12c01 ~]$ du -h linuxx64_12201_database.zip 3.3G linuxx64_12201_database.zip [oracle@12c01 ~]$ unzip linuxx64_12201_database.zip
PRVF-0002 : could not retrieve local node name
解压完成后 cd 进入其解压后的目录database 输入命令： cd database 执行安装 输入命令： ./runInstaller
缺包，自行补包。
root 执行完点击ok，12c软件安装结束。
dbca 建库。
[oracle@12c01 database]$ dbca
[oracle@12c01 ~]$ sqlplus / as sysdba
