        db2 v11在redhat7上安装:

  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) =
   Default database monitor switches
     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
     Unit of work                            (DFT_MON_UOW) = OFF
   Monitor health of instance and databases   (HEALTH_MON) = OFF
   SYSMON group name                        (SYSMON_GROUP) =
   Database monitor heap size (4KB)          (MON_HEAP_SZ) = AUTOMATIC(90)
  
  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
 
  db2 connet to 数据库
