[[email protected] ~]# sysctl -p   --使参数生效

2.1 配置用户shell限制

[[email protected] ~]# vi /etc/security/limits.conf
oracle          soft    nproc           2047
oracle          hard    nproc           16384

oracle          soft    memlock         3145728
oracle          hard    memlock         3145728
oracle          soft    stack           10240
oracle          hard    stack           10240

2.2 模块配置

[[email protected] ~]# vi /etc/pam.d/login
session    required     /lib64/security/pam_limits.so

2.3 创建用户和组

 groupadd oinstall
 groupadd dba
 useradd -m -g oinstall -G dba oracle
 echo "oracle"|passwd --stdin oracle
 mkdir -p /DBSoft/product/12.2.0.1/db_1
 chown -R oracle:oinstall /DBSoft

2.4 操作系统profile配置

[[email protected] ~]# vi /etc/profile
if [ \$USER = "oracle" ]; then  
    if [ \$SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
fi

2.5 配置oracle用户环境变量

vi /home/oracle/.bash_profile
export EDITOR=vi
export ORACLE_SID=woo
export ORACLE_BASE=/DBSoft
export ORACLE_HOME=\$ORACLE_BASE/product/12.2.0.1/db_1
export LD_LIBRARY_PATH=\$ORACLE_HOME/lib
export PATH=\$ORACLE_HOME/bin:\$PATH
umask 022

2.6 关闭防火墙、selinux

chkconfig --level 345 ip6tables off
chkconfig --level 345 iptables off
service ip6tables stop
service iptables stop
sed -i "/^SELINUX=/s#enforcing#disabled#" /etc/selinux/config

2.7 修改hosts文件

vi /etc/hosts
192.168.3.2  leo

3 安装数据库软件

[[email protected] ~]$ ls
linuxx64_12201_database.zip
[[email protected] ~]$ unzip linuxx64_12201_database.zip
[[email protected] ~]$ ll
total 3372760

[[email protected] database]$ ./runInstaller -silent -noconfig -responseFile /home/oracle/database/response/db_install.rsp -ignorePrereq

   ACTION: Oracle recommends placing this Central Inventory in a location outside the Oracle base directory.
You can find the log of this install session at:
 /DBSoft/oracle/oraInventory/logs/installActions2019-07-09_10-23-25AM.log

提示执行root脚本：
[[email protected] database]$ The installation of Oracle Database 12c was successful.
Please check ‘/DBSoft/oracle/oraInventory/logs/silentInstall2019-07-09_10-23-25AM.log‘ for more details.
As a root user, execute the following script(s):
    1. /DBSoft/oracle/oraInventory/orainstRoot.sh
    2. /DBSoft/oracle/product/12.2.0.1/db_1/root.sh
Successfully Setup Software.

3.1 GUI界面









这是一个bug，已经执行并且添加，不用管，详见supprt (文档 ID 2287806.1)，点击忽略即可。



3.2 执行root脚本

[[email protected] ~]# /DBSoft/oracle/product/12.2.0.1/db_1/root.sh 

4 DBCA创建数据库
















修改日志组的大小为250M



4.1 修改数据库配置

SQL> alter system set processes= 2000 scope=spfile;
SQL> alter system set session_cached_cursors=300 scope=spfile
SQL> alter system set open_cursors=350 scope=spfile;
SQL> alter system set sessions=2000 scope=spfile;
SQL> alter system set shared_pool_size=5120M scope=spfile;
SQL> alter system set "_allow_insert_with_update_check"=true;

5 安装OEM
注意：OEM 13cR2安装包下载之后不要解压，直接执行em13200_linux64.bin文件会自动解压到／tmp目录中，随后会会调用安装程序起图形界面，这个过程大约5-10分钟，需耐心等待。













注意：看到这些信息要在数据库端修改对应的参数再重新执行即可。







注意：经过3.5个小时的安装终于出现弹出需要执行allroot.sh脚本界面，安装基本告成。执行allroot.sh脚本

6 使用OEM
打开浏览器进入OEM页面https://192.168.3.2:7802/em 用户名sysman密码oracle123
进入之后接受许可协议





7 安装部署Agent
7.1 添加地址解析

在所有受管理的服务器增加OMS服务解析地址：
# echo “192.168.3.3     oem13c” >> /etc/hosts

7.2 部署Agent

7.3 执行root.sh脚本

所有受管节点以root用户执行root.sh脚本
[[email protected] ~]# /DBSoft2/oracle/product/oem13c/AgentHome/agent_13.2.0.0.0/root.sh

至此，EM13C Agent 部署完成。
