整个过程下载可能会比较慢,最好是抓取下载链接,然后使用wget下载,例如
[root@terwergreen opt]# wget https://download.oracle.com/otn/linux/oracle12c/122010/linuxx64_12201_database.zip?AuthParam=1552132547_497757efbab4cd9c91b5d9c3fde56635

1.root身份安装依赖包:
yum -y install binutils compat-libcap1 compat-libstdc++-33 compat-libstdc++-33*.i686 elfutils-libelf-devel gcc gc
2.建立用户和组:
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba,oper oracle
echo "123456" | passwd --stdin oracle #oracle用户的登录密码,后续登录要用,记着。
3.创建安装目录:
mkdir -p /orcl/app/oracle/product/12.1.0/db_1
chown -R oracle:oinstall /orcl/app
chmod -R 775 /orcl/app
4.修改内核参数vim /etc/sysctl.conf
,添加:
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 1200000000
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
改好后,使之生效
sysctl -p
另外 上面的kernel.shmmax = 1200000000
可能会有问题,后面咱们再说。
或者你直接现在就写成4098955264
5.改文件限制:vim /etc/security/limits.conf
,添加:
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
注意:修改此文件是即时生效的,但可能要重登录后再看
6.以及vim /etc/pam.d/login
,添加:
session required pam_limits.so
7.修改ulimit:vim /etc/profile
,添加:
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536a
else
ulimit -u 16384 -n 65536
fi
fi
8.修改环境变量。vim ~oracle/.bash_profile
,添加:
ORACLE_BASE=/orcl/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
ORACLE_SID=orcl
export ORACLE_BASE ORACLE_HOME ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH
export PATH
9.用yum remove *openjdk*
把系统自带的openjdk卸载,再安装
sun jdk:rpm -ivh jdk-8u144-linux-x64.rpm
。

(openjdk环境安装oracle GUI会报class not found的错)。然后$>java -version检查一下安装是否成功。上述工作完成后,建议重启系统。
