Centos7安装Oracle11gR2各种问题

安装乱码:

安装前设置一下环境变量，用英文安装就不会乱码了

export LC_ALL=en_US.UTF-8

不能使用Backspace:

vim .zshrc
    stty erase ^h

xhost: unable to open display:

oracle user $

vim .zshrc 

    export DISPLAY=:0.0

root user #

xhost +

弹回Oracle安装图形界面:

linux root user #

yum -y groupinstall "GNOME Desktop" "Graphical Administration Tools"

本机windows

ipconfig，查看地址

开启Xmanager - Passive

linux oracle user $

vim .zshrc 

    export DISPLAY=windowsIPAddress:0.0 

source .zshrc 

cd /u01/soft/database

./runInstaller

内核参数配置/etc/sysctl.conf：

kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
fs.aio-max-nr = 1048576
fs.file-max = 6815744
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

Hard limits for "maximum open file descriptors":

vim /etc/security/limits.conf

    * hard nofile 65536

ulimit -a

Error in invoking target 'agent nmhs' of makefile:

vim /u01/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk

大概176行

$(MK_EMAGENT_NMECTL)更改为$(MK_EMAGENT_NMECTL) -lnnz11

Retry

iptables设置

systemctl stop firewald.service
systemctl disable firewald.service
yum install iptables-services iptables-devel
vim /etc/sysconfig/iptables
    在:INPUT ACCEPT [0:0]下面添加
    # Oracle 11G R2 configure
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 1158 -j ACCEPT
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 1521 -j ACCEPT
vim /etc/sysctl.conf
    net.ipv4.ip_forward=1
sysctl -p
systemctl enable iptables.service
systemctl start iptables.service

关闭selinux

vim /etc/selinux/config
    将SELINUX=enforcing改为
    SELINUX=disabled

reboot

Oracle EM问题

检查监听器是否开启
    lsnrctl status

检查em
    emctl status dbconsole

检查数据库是否开启
    sqlplus / as sysdba
    select instance_name, status from v$instance;

检查iptables设置
    iptables -L -n

检查selinux是否关闭
    getenforce
    sestatus

浏览器打开https://oracle服务器IP:1158/em
    用户名：sys
    口令：
    连接身份：SYSDBA

sqlplus初始化配置

vim /u01/app/oracle/product/11.2.0/dbhome_1/sqlplus/admin/glogin.sql
    set linesize 148;
    set pagesize 39;
    col tablespace_name for a15;
    col file_name for a50;
    col bytes for 999,999,999;
    col owner for a15;
    col segment_name for a30;
    col segment_type for a20;

开机自动启动问题（最好不要用这个，Oracle有个组件好像能实现这个功能，具体忘了）

oracle user$

自行在root下使用visudo添加oracle用户

sudo vim /etc/oratab
    将orcl:/u01/app/oracle/product/11.2.0/dbhome_1:N改为(否则dbstart无效)
    orcl:/u01/app/oracle/product/11.2.0/dbhome_1:Y

vim /u01/app/oracle/product/11.2.0/dbhome_1/bin/dbstart
    将ORACLE_HOME_LISTNER=$1改为
    ORACLE_HOME_LISTNER=$ORACLE_HOME

vim /u01/app/oracle/product/11.2.0/dbhome_1/bin/dbshut
    将ORACLE_HOME_LISTNER=$1改为
    ORACLE_HOME_LISTNER=$ORACLE_HOME

使用公私钥登录方式

本机

ssh-keygen -t rsa
scp ~/.ssh/id_rsa.pub oracle@服务器地址:/home/oracle

服务器

cd
mkdir .ssh
touch .ssh/authorized_keys
cat id_rsa.pub >> .ssh/authorized_keys
