Linux主机名：infsrv

informix安装包：ibm.ids.14.10.FC10W1.LNX.tar

informix服务名：infor

内核参数调整

cat >> /etc/sysctl.conf << EOF kernel.shmmax = 4398046511104 kernel.shmall = 4294967296 kernel.shmmni = 4096 kernel.sem = 100 32000 1024 2048 vm.swappiness = 0 EOF

cat >> /etc/security/limits.conf <<EOF * soft nproc 40960 * hard nproc 81920 root soft nproc unlimited * soft nofile 102400 * hard nofile 204800 root soft nofile unlimited EOF

环境准备

setenforce 0sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config

disable_FW

create informix user & group

groupadd -g 1000 informix useradd -g informix -d /home/informix -m -s /bin/bash informix passwd informix

su - informix cat >> ~/.bash_profile << EOF export INFORMIXDIR=/opt/informix export INFORMIXSQLHOSTS=$INFORMIXDIR/etc/sqlhosts export ONCONFIG=onconfig.infor export INFORMIXSERVER=infor export PATH=$INFORMIXDIR/bin:$PATH EOF

注：INFERMIXSERVER = instance name (sqlhost) = DBSERVERNAME (onconfig)

create DB folder

mkdir -p /data/informix chmod 755 /data chmod 755 /data/informix chown informix:informix /data/informix

以 root 身份登录，创建"rootdbs"数据库空间文件：

rootdbs必须660

create datafile folders

pvcreate /dev/sdb vgcreate vgdata /dev/sdb lvcreate -n lvrootchk -L 1050M vgdata lvcreate -n lvplogchk -L 1050M vgdata lvcreate -n lvllogchk -L 1050M vgdata lvcreate -n lvtempchk01 -L 1050M vgdata lvcreate -n lvsbspace01 -L 1050M vgdata lvcreate -n lvdatachk01 -L 1050M vgdata cd /dev/vgdata chown informix:informix lv* chmod 0660 lv* ll ../dm-[3-8] mkdir -p /data/informix chmod 775 /data chmod 775 /data/informix chown informix:informix /data/informix cd /data/informix ln -s /dev/vgdata/lvrootchk rootchk ln -s /dev/vgdata/lvplogchk plogchk ln -s /dev/vgdata/lvllogchk llogchk ln -s /dev/vgdata/lvtempchk01 tempchk01 ln -s /dev/vgdata/lvsbspace01 sbspace01 ln -s /dev/vgdata/lvdatachk01 datachk01

Install informix DB (root account)

cd /software
tar -xvf /software/ibm.ids.14.10.FC10W1.LNX.tar
tar -xvf /software/ibm.ids.14.10.FC10W1.LNX.tar -C /opt/informix/

#选择非GUI模式安装，其他根据提示保持默认选项，也就是回车
