1、设置主机名和修改/etc/hosts一致
hostnamectl --static set-hostname db2v11
2、安装操作系统依赖包
yum install libstdc++.so.6
3、解压包并安装
./db2_deinstall
安装目录，选择推荐目录即可(可以修改目录，如果不修改/预留大小为6G)
Enter "help" to redisplay product names. --------------- 选择安装产品类型，这里选择SERVER
Do you want to install the DB2 pureScale Feature? [yes/no] ---------------- 选择是否安装pureScale功能，这里选择不安装
4、安装完后初始化
groupadd db2iadm1
groupadd db2fadm1
useradd db2inst1 -G db2iadm1
useradd db2fenc1 -G db2fadm1
cd /opt/ibm/db2/V11.1/instance/
./db2icrt -a server -p 50000 -u db2fenc1 db2inst1
5、激活license
以下操作全部以db2inst1用户执行查看license信息
db2licm -l
license激活
db2licm -a /usr/local/src/db2ese_c.lic
6、修改实例
a、修改db2nodes.cfg（可选）位置在instance用户的$HOME/sqllib/.文件格式是:
<logic port> <hostname> <logic port> //主机名要与/etc/hosts 的主机名一致 或hostname命令查看
(2) 检查services文件（多节点配置自动生成多个服务端口）
vi /etc/services
DB2c_db2inst1 50000/tcp // 要与dbm SVCENAME一致
(3) 启动实例：
配置环境变量 --root用户和db2inst1用户
# vi ~/.bash_profile
$ vi ~/.bash_profile
./home/db2inst1/sqllib/db2profile # 增加该行代码
# source ~/.bash_profile
$ source ~/.bash_profile
设置服务名称
$ db2 update dbm cfg using SVCENAME db2inst1
设置注册变量
$ db2set DB2COMM=tcpip
启动实例
$ db2start
7、创建数据库
[root@localhost ~]# su - db2inst1
[db2inst1@localhost ~]$ cd /opt/ibm/db2/V9.7/bin
[db2inst1@localhost bin]$ ./db2sampl
8、调整数据库参数
db2set DB2_PARALLEL_IO=*
db2set DB2_SKIPINSERTED=YES
db2set DB2_USE_ALTERNATE_PAGE_CLEANING=YES
db2set DB2_EVALUNCOMMITTED=YES
db2set DB2_ANTIJOIN=EXTEND
db2set DB2_SKIPDELETED=YES
db2set DB2CODEPAGE=1208
db2 update dbm cfg using DFT_MON_BUFPOOL on
db2 update dbm cfg using DFT_MON_LOCK on
db2 update dbm cfg using DFT_MON_SORT on
db2 update dbm cfg using DFT_MON_STMT on
db2 update dbm cfg using DFT_MON_TABLE on
db2 update dbm cfg using DFT_MON_TIMESTAMP on
db2 update dbm cfg using DFT_MON_UOW on
[db2inst1@db2v11 ~]$ db2 get dbm cfg |grep -i mon
Transaction processor monitor name (TP_MON_NAME) =

Buffer pool (DFT_MON_BUFPOOL) = OFF
Lock (DFT_MON_LOCK) = OFF
Sort (DFT_MON_SORT) = OFF
Statement (DFT_MON_STMT) = OFF
Table (DFT_MON_TABLE) = OFF
Timestamp (DFT_MON_TIMESTAMP) = ON

Monitor health of instance and databases (HEALTH_MON) = OFF
SYSMON group name (SYSMON_GROUP) =

授权
db2 get dbm cfg |grep -i sysmon
groupadd db2user
db2 update dbm cfg using SYSMON_GROUP db2user
db2 attach to db2inst1
db2 force applications all
db2stop force
db2 get dbm cfg |grep -i sysmon
useradd -g db2user -d /home/dpmmon -s /bin/bash -m dpmmon
su - db2inst1
