linux安装oracle笔记

linux安装oracle

.增大swap空间，内存大于8G后swap跟内存同等大小即可
    mkdir /home/swap
    cd /home/swap
    dd if=/dev/zero of=swapfile bs=1G count=
    mkswap swapfile
    swapon swapfile #增加到swap分区（31G + 31G = 62G）
    #设置开机自动添加swapfile
    vi /etc/fstab:
    /home/swap/swapfile                                  swap    defaults         

.关闭防火墙和SeLinux
    ntsysv/chkconfig
    service iptables stop

    /usr/sbin/sestatus -v
    setenforce

.安装依赖包
    #检查依赖包安装情况
    rpm -q binutils compat-libstdc++- compat-libstdc++- elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc glibc-common glibc-devel glibc-devel glibc-headers ksh libaio libaio libaio-devel libaio-devel libgcc libgcc libstdc++ libstdc++ libstdc++-devel make sysstat
    未安装的就手动安装上

.设置系统参数
    #如果系统是oracle linux的话，多半都已经帮你预设了
    vi /etc/security/limits.conf:
    oracle soft nproc
    oracle hard nproc
    oracle soft nofile
    oracle hard nofile
    *   -   core
    *   -   data            unlimited
    *   -   fsize           unlimited
    *   -   memlock         unlimited
    *   -   nofile
    *   -   rss             unlimited
    *   -   stack           unlimited
    *   -   cpu             unlimited
    *   -   nproc           unlimited
    *   -   as              unlimited
    *   -   maxlogins
    *   -   maxsyslogins
    *   -   priority        unlimited
    *   -   locks           unlimited
    *   -   sigpending      unlimited
    *   -   msgqueue        unlimited

    vi /etc/pam.d/login:
    session    required     pam_limits.so
    session    required     /lib/security/pam_limits.so

    vi /etc/sysctl.conf:
    fs.file-max =
    fs.aio-max-nr =
    kernel.shmall =
    kernel.shmmax =
    kernel.shmmni =
    kernel.sem =
    net.ipv4.ip_local_port_range =
    net.core.rmem_default =
    net.core.rmem_max =
    net.core.wmem_default =
    net.core.wmem_max =
    #修改sysctl.conf并使其立即生效
    sysctl -p

.创建用户组和用户
    groupadd oinstall
    groupadd dba

    useradd -g oinstall -G dba oracle
    passwd oracle #密码设置为Oracle123$

.安装oracle
    export JAVA_HOME=/home/oracle/jdk
    export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH
    export PATH=$JAVA_HOME/bin:$PATH

    SecureCRT会话选项->远程/X11->转发X11数据包(F)（强制鉴权不要选上！！）

    ./runInstaller
    dbca
    netca

    数据库账户密码：sys/eastcom

老库导新库，只导出用户的对象定义：

CREATE OR REPLACE DIRECTORY DATA_PUMP_DIR AS '/home/oracle/admin/ipnet/dpdump/';
GRANT READ, WRITE ON DIRECTORY DATA_PUMP_DIR to sys;

CREATE TABLESPACE FM
LOGGING
DATAFILE '/home/oradata/fm.dbf'
SIZE 30720M;

CREATE USER fm IDENTIFIED BY fm1234
DEFAULT TABLESPACE FM;

GRANT CONNECT, RESOURCE, CREATE ANY VIEW TO fm;

DROP USER fm CASCADE;
