Redhat Linux AS4 安装Oracle 10g(包括启动)(2)

除sysstat包都成功安装，

sysstat包在4号盘上，rpm -i sysstat-5.0.5-1.i386.rpm

4、安装Oracle

1)添加用户组

判断用户和组是否存在

grep dba /etc/group

grep oinstall /etc/group

id oracle

id nobody

有则不添加

groupadd oinstall

groupadd dba

useradd -g oinstall -G dba oracle

--oracle 已经存在 但不是 oinstall组，也非dba组成员

usermod -g oinstall -G dba oracle

useradd nobody

2)内核参数

Parameter Value File

semmsl 250 /proc/sys/kernel/sem

semmns 32000

semopm 100

semmni 128

shmall 2097152 /proc/sys/kernel/shmall

shmmax Half the size of physical memory (in bytes) /proc/sys/kernel/shmmax

shmmni 4096 /proc/sys/kernel/shmmni

file-max 65536 /proc/sys/fs/file-max

ip_local_port_range Minimum: 1024 /proc/sys/net/ipv4/ip_local_port_range

Maximum: 65000

rmem_default 1048576 /proc/sys/net/core/rmem_default

rmem_max 1048576 /proc/sys/net/core/rmem_max

wmem_default 262144 /proc/sys/net/core/wmem_default

wmem_max 262144 /proc/sys/net/core/wmem_max

命令

semmsl, semmns, semopm, and semmni # /sbin/sysctl -a | grep sem

shmall, shmmax, and shmmni # /sbin/sysctl -a | grep shm

file-max # /sbin/sysctl -a | grep file-max

ip_local_port_range # /sbin/sysctl -a | grep ip_local_port_range

rmem_default # /sbin/sysctl -a | grep rmem_default

rmem_max # /sbin/sysctl -a | grep rmem_max

wmem_default # /sbin/sysctl -a | grep wmem_default

wmem_max # /sbin/sysctl -a | grep wmem_max

修改配置文件/etc/sysctl.conf,增加或修改

kernel.shmall = 2097152

kernel.shmmax = 2147483648

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 1048576

net.core.rmem_max = 1048576

net.core.wmem_default = 262144

net.core.wmem_max = 262144

重新启动

3)设置oracle用户的shell

a)增加如下行到/etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

b)增加下列行到/etc/pam.d/login

session required /lib/security/pam_limits.so

session required pam_limits.so

c)修改Shell默认启动文件

Bourne,Bash,Korm shell下增加下列行到/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

C shell下，增加下列行到/etc/csh.login

if ( $USER == "oracle" ) then

limit maxproc 16384

limit descriptors 65536

endif

4)创建需要的目录

mkdir /app/oracle

chown -R oracle:oinstall /app/oracle

chmod -R 775 /app/oracle

chown -R oracle:oinstall /app/oradata
