- 前期准备
1.创建目录存放安装包
mkdir /opt/software/2.上传安装包并解压
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip3.修改hostname
vi /etc/hosts #末尾添加ip+名称 如：172.19.20.92 citrus_014.修改系统参数
vi /etc/sysctl.conf # 物理内存32G时
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 4194304
kernel.shmmax = 17179869184
kernel.shmmni = 4096
kernel.sem = 250 128000 100 1024
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 # 物理内存16G时
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 8589934592
kernel.shmmni = 4096
kernel.sem = 250 128000 100 1024
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- - 保存后运行 sysctl -p使其生效
sysctl -p5.修改认证模块
vi /etc/security/limits.conf # 末尾添加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 655366.修改用户登录
vi /etc/pam.d/login # 末尾添加
session required /lib/security/pam_limits.so
session required pam_limits.so7.修改配置文件
vi /etc/profile # 末尾添加
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536

fi8.关闭防火墙（安装VNC时已关闭，检查是否关闭即可）
systemctl status firewalld.service # 首先查看防火墙的状态
systemctl stop firewalld service # 关闭防火墙
systemctl disable firewalld.service # 开机禁止防火墙服务器
systemctl enable firewalld.service # 开机启动防火墙服务器9.关闭selinux
# 临时关闭：setenforce 0
vim /etc/selinux/config # 设置SELINUX=disabled10.创建用户组
groupadd oinstall
groupadd dba useradd -g oinstall -g dba -m oracle
passwd oracle
# 弹出输入密码，输入两次确认11.创建存放安装的目录及数据文件存放目录
mkdir /opt/oracle/
mkdir /opt/oracle/oraInventory12.更改文件夹隶属给oracle用户
chown -R oracle:dba /opt/oracle/oraInventory
chown -R oracle:oinstall /opt/oracle
chmod 777 /opt/oracle # 权限- 安装所有依赖项 （并带有相应的备注说明，并非必须全部完成哦~ 但若全部完成的话，则无需担心后续提示信息）。

14.配置oracle用户的环境变量（我这里是喜欢提前配置）
su - oracle vi .bash_profile export ORACLE_SID=orcl
export ORACLE_BASE=/opt/oracle/app
# 注意这里是安装oracle时的目录，默认的好像是/home/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/rdbms/lib
export PATH=$PATH:$ORACLE_HOME/bin
export LIBPATH=$ORACLE_HOME/rdbms/lib:$ORACLE_HOME/lib:$LIBPATH全部评论 (0)
