1. Prepare the operating system environment
Close selinx (the configuration file of selinux is /etc/selinux/config), and the configuration will take effect after restarting the machine
turn off firewall
2. Create the required users (oinstall) and groups (oinstall, dba)
3. Create the required directory (/u01) and modify the permissions
4. Configure the local yum source and install the package
12c需要安装的包有binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat compat-libcap* numactl-devel unix0DBC unix0DBC-devel openmotif22 openmotif compat-db libXp
5. Configure the kernel parameters (the configuration file is /etc/sysctl.conf)fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 //This should already exist in the file, and in general the value is greater than the recommended value, so it can be deleted kernel.shmmax = 536870912 //same as above 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 = 1048586
6. Configure soft and hard limits (configuration file is /etc/security/limits.conf)
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240
7. Configure access restrictions (the configuration file is /etc/oam.d/login)
session required /lib64/security/pam_limits.so [root@OCP3 ~]# xhost +8. Start the installation
Configure local parsing before installation
[root@OCP3 ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.40.13 OCP3
I use the zip package for the installation here, just copy the package to /home/oracle, decompress it, it should be a directory named database after decompression, modify the group of this directory to oinstall, and the owner to oracle, The permission is 775, then log in with the oracle user, enter the database/ directory, execute the script, and install
[oracle@OCP3 database]# ./runInstaller
Then select the installation option you need and follow it step by step.
