注:以下所述内容均以db2 for linux v9.7 x64 enterprise edition为标准
1 先决条件
操作系统版本 Linux 支持的最低级别操作系统包括：
Red Hat Enterprise Linux (RHEL) 5 更新 2.0.4
SUSE Linux Enterprise Server (SLES) 10 Service Pack 2
SUSE Linux Enterprise Server (SLES) 11
Ubuntu 8.0.4.1
程序包要求 Libaio
compat-libstdc++(包含 libstdc++.so.5)
libstdc++(libstdc++.so.6)
pdksh 或 ksh93
rsh-server
xinetd
openssh
openssh-server
nfs-utils
安全选项 SELINUX保持关闭
2 修改内核参数(以60%系统容量)
/etc/sysctl.conf kernel.shmmni=4096
kernel.shmmax=329853488332
kernel.shmall=80530636
kernel.sem=250 256000 32 4096
kernel.msgmni=32768
kernel.msgmax=65536
kernel.msgmnb=65536
- 导出原db2 database参数以参考
db2inst3@/home/db2inst3>db2cfexp ./ods5cfg.templ template
db2inst3@/home/db2inst3>cat ods5cfg.templ
4创建用户
groupadd -g 1000 db2iadm1
groupadd -g 1001 db2fadm1
useradd -u 1000 -g db2iadm1 -d /home/db2inst1 -m db2inst1
useradd -u 1001 -g db2fadm1 -d /home/db2fenc1 -m db2fenc1
echo '1q2w3e' |passwd --stdin db2inst1
echo '1q2w3e' |passwd --stdin db2fenc1
5创建目录和挂载信息
mkdir /database
mkdir /db2log
mkdir /db2arch
mkdir /backup
chown db2inst1:db2iadm1 /database
chown db2inst1:db2iadm1 /db2log
chown db2inst1:db2iadm1 /db2arch
chown db2inst1:db2iadm1 /backup
6此次在全新环境和跨平台安装,不采用响应式和向导安装,使用db2_install安装产品组件
