Oracle RAC集群搭建(二)-基础环境配置

01,创建用户,用户组

[root@rac1 ~]# groupadd -g 501 oinstall
[root@rac1 ~]# groupadd -g 502 dba
[root@rac1 ~]# groupadd -g 503 asmadmin
[root@rac1 ~]# groupadd -g 504 asmdba
[root@rac1 ~]# groupadd -g 505 asmoper
[root@rac1 ~]# useradd -u 501 -g oinstall -G asmadmin,asmdba,asmoper grid
[root@rac1 ~]# useradd -u 502 -g oinstall -G dba,asmdba oracle
passwd oracle
passwd grid             ----配置密码

02,配置hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.171 rac1
192.168.0.177 rac2
192.168.0.173 rac1vip
192.168.0.174 rac2vip
172.168.0.171 rac1prv
172.168.0.177 rac2prv
192.168.0.176 dbscan

03,关闭时间同步

mv /etc/ntp.conf /etc/ntp.conf.bak

04, 修改内核

vim /etc/sysctl.conf

kernel.shmmni =
kernel.sem =
fs.file-max =
net.ipv4.ip_local_port_range =
net.core.rmem_default =
net.core.rmem_max =
net.core.wmem_default =
net.core.wmem_max = 

sysctl -p   立即生效

05, 限制参数

/etc/security/limits.conf

grid soft nproc
grid hard nproc
grid soft nofile
grid hard nofile
oracle soft nproc
oracle hard nproc
oracle soft nofile
oracle hard nofile 

06, 配置profile

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
　　if [ $SHELL = "/bin/ksh" ]; then
　　　　ulimit -p
　　　　ulimit -n
　　else
　　　　ulimit -u  -n
　　fi
　umask
fi

07,登录限制

 /etc/pam.d/login
session required pam_limits.so

08,创建目录

[root@rac1 ~]# mkdir -p /oracle/app/oraInventory
[root@rac1 ~]# chown -R grid:oinstall /oracle/app/oraInventory
[root@rac1 ~]#  chmod -R 775 /oracle/app/oraInventory

[root@rac1 ~]# mkdir -p /oracle/11.2.0/grid/crs/
[root@rac1 ~]# chown -R grid:oinstall /oracle/11.2.0/grid
[root@rac1 ~]#  chmod -R 775 /oracle/11.2.0/grid

[root@rac1 ~]# cd /oracle/11.2.0
[root@rac1 11.2.]# mkdir 11.2.0
[root@rac1 11.2.]# chown -R grid:oinstall 11.2.0
[root@rac1 11.2.]# chmod -R 775 11.2.0

[root@rac1 11.2.]# mkdir -p /oracle/app/oracle
[root@rac1 11.2.]# chown -R oracle:oinstall /oracle/app/oracle
[root@rac1 11.2.]# chmod -R 775 /oracle/app/oracle
[root@rac1 11.2.]# mkdir -p /oracle/app/oracle/product/11.2.0/db_1
[root@rac1 11.2.]# chown -R oracle:oinstall /oracle/app/oracle/product/11.2.0/db_1
[root@rac1 11.2.]# chmod -R 775 /oracle/app/oracle/product/11.2.0/db_1

09,关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl status firewalld.service

10.软件环境安装

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n' binutils \
compat-libstdc++- \
elfutils-libelf \
elfutils-libelf-devel \
gcc \
gcc-c++ \
glibc \
glibc-common \
glibc-devel \
glibc-headers \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
