安装依赖

安装可能用到的工具

yum install epel-release
yum clean all
yum makecache fast
yum install vim unzip rlwrap

配置安装环境

创建 oracle 用户

groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle

创建 oracle 安装目录

mkdir -p /opt/oracle/app/product/11.2.0
mkdir -p /opt/oracle/app/oradata
mkdir -p /opt/oracle/app/fast_recovery_area
mkdir -p /opt/oracle/inventory
chown -R oracle:oinstall /opt/oracle
chmod -R 775 /opt/oracle

修改 sysctl.conf

cat << EOF >> /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
#物理内存一半和4G中的较大者
kernel.shmmax = 4294967296
#shmmax / 4k (getconf PAGESIZE)
kernel.shmall = 1048576

EOF
sysctl -p

修改 limits.conf

cat << EOF >> /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
EOF

修改 login

session required  /lib64/security/pam_limits.so
session required pam_limits.so
EOF

修改 profile

cat << EOF >> /etc/profile
if [ \$USER = "oracle" ] ; then
    if [ \$SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
    umask 022
fi
EOF

修改 oracle 用户的 .bash_profile

cat << EOF >> /home/oracle/.bash_profile
export ORACLE_BASE=/opt/oracle/app
export ORACLE_HOME=\$ORACLE_BASE/product/11.2.0
export ORACLE_SID=orcl
export PATH=\$PATH:\$ORACLE_HOME/bin

安装数据库

上传数据库软件到 /root 下，解压

unzip linux.x64_11gR2_database_1of2.zip -d /home/oracle/
unzip linux.x64_11gR2_database_2of2.zip -d /home/oracle/
chown -R oracle.oinstall /home/oracle/database

切换到 oracle 用户，后续操作都在该 oracle 用户下执行
```
su - oracle
```

创建 response 文件

cd /home/oracle
cp database/response/*.rsp ./

修改 db_install.rsp

sed -i \
    -e '/^oracle.install.option=/s#=.*$#=INSTALL_DB_SWONLY#' \
    -e '/^UNIX_GROUP_NAME=/s#=.*$#=oinstall#' \
    -e '/^INVENTORY_LOCATION=/s#=.*$#=/opt/oracle/inventory#' \
    -e '/^SELECTED_LANGUAGES=/s#=.*$#=en,zh_CN#' \
    -e '/^ORACLE_HOME=/s#=.*$#=/opt/oracle/app/product/11.2.0#' \
    -e '/^ORACLE_BASE=/s#=.*$#=/opt/oracle/app#' \
    -e '/^oracle.install.db.InstallEdition=/s#=.*$#=EE#' \

    -e '/^SID=/s#=.*$#=orcl#' \
    -e '/^SYSPASSWORD=/s#=.*$#=111111#' \
    -e '/^SYSTEMPASSWORD=/s#=.*$#=111111#' \
    -e '/^CHARACTERSET=/s#=.*$#=ZHS16GBK#' \
    /home/oracle/dbca.rsp

安装 oracle 软件

cd /home/oracle/database
./runInstaller -silent -responseFile /home/oracle/db_install.rsp -ignorePrereq
#安装成功后，系统提示需要在 root 下执行两个脚本
/opt/oracle/invertory/orainstRoot.sh
/opt/oracle/app/product/11.2.0/root.sh

配置监听

netca /silent /responseFile /home/oracle/netca.rsp
#配置成功后，监听启动，查看监听状态
lsnrctl status

创建数据库

dbca -silent -responseFile /home/oracle/dbca.rsp
#查看屏幕输出的创建进度

简单使用
