环境配置
公司要上新一体机，需要对新版本研究下，自己先在电脑上虚拟一下Oracle exadata环境。方便研究。谢谢大家的关注
一、安装操作系统
[root@masterdb ~]# cat /etc/system-release Oracle Linux Server release 7.4
二、配置网络
配置管理网络和infiniband心跳网络 必须静态
计算节点
nmcli connection add type ethernet con-name static-eth0 ifname eth0 ip4 10.201.0.231/24 gw4 10.201.0.254
nmcli connection add type ethernet con-name static-eth1 ifname eth1 ip4 10.0.0.231/24 gw4 10.0.0.254
cell节点
nmcli connection add type ethernet con-name static-eth0 ifname eth0 ip4 10.201.0.232/24 gw4 10.201.0.254
nmcli connection add type ethernet con-name static-eth1 ifname eth1 ip4 10.0.0.232/24 gw4 10.0.0.254
三、配置yum
vim /etc/yum.repos.d/iso.repo
[ISO] name=iso
baseurl=file:///mnt
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=0
#priority=20
enabled=1
yum repolist
四、安装cell依赖包
yum install -y lm_sensors net-snmp perl-Compress perl-HTML perl-libwww
五、配置hosts文件
#db
10.201.0.231 masterdb
10.0.0.231 masterdb
#cell
10.201.0.232 slavecell
10.0.0.232 slavecell
六、创建目录
mkdir /var/log/oracle
chmod 775 /var/log/oracle
mkdir /opt/oracle
chmod 775 /opt/oracle
七、配置系统内核参数
mv /etc/sysctl.conf /etc/sysctl.conf.bak
注：sysctl.conf文件的原有参数可能会对启动celsrv服务有影响，建议不用原有的参数。
vi /etc/sysctl.conf
fs.file-max = 65536
fs.aio-max-nr = 500000000
vm.min_free_kbytes = 512000
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 8388608
net.core.wmem_max = 4194304
执行/sbin/sysctl -p 使参数生效
vi /etc/security/limits.conf
root soft nofile 131072
root hard nofile 131072
celladmin soft nproc 2047
celladmin hard nproc 16384
celladmin soft nofile 131072
celladmin hard nofile 131072
登录策略
vi /etc/pam.d/login
session required pam_limits.so
八、配置RDS协议
12c后需要RDS协议的支持，否则cellsrv服务无法启动
12c以前，除支持RDS协议，还支持UDP协议
手动加载RDS协议
modprobe rds
modprobe rds_tcp
modprobe rds_rdma
设置RDS随系统启动时自动加载RDS协议
vi /etc/modprobe.d/rds.conf
install rds /sbin/modprobe --ignore -install rds && /sbin/modprobe rds_tcp && /sbin/modprobe rds_rdma
九、关闭防火墙和selinux
systemctl stop firewalld.service
vim /etc/selinux/config
SELINUX=enforcing => disabled
十、安装存储软件
1、安装java
unzip V983555-01.zip
tar -xvf nfsimg-18.1.20.0.0-190911-cell.tar
cd cellbits
tar -xjvf cellrpms.tbz
rpm -ivh jdk1.8-1.8.0_221-fcs.x86_64.rpm
2、解压存储软件、
/usr/local/src/software/cellbits unzip cell.bin rpm -ivh cell-18.1.20.0.0_LINUX.X64_190911-1.x86_64.rpm error: Failed dependencies: net-snmp-utils is needed by cell-18.1.20.0.0_LINUX.X64_190911-1.x86_64 perl(Env) is needed by cell-18.1.20.0.0_LINUX.X64_190911-1.x86_64 perl(LWP) is needed by cell-18.1.20.0.0_LINUX.X64_190911-1.x86_64 perl(XML::Simple) is needed by cell-18.1.20.0.0_LINUX.X64_190911-1.x86_64
安装依赖包
for i in `ls perl*`; do rpm -ivh --nodeps $i; done
继续安装
[root@slavecell cellbits]# rpm -ivh cell-18.1.20.0.0_LINUX.X64_190911-1.x86_64.rpm Preparing... ################################# [100%] Updating / installing... 1:cell-18.1.20.0.0_LINUX.X64_190911################################# [100%] Installation SUCCESSFUL. Done. Please Login as user celladmin, startup RS and MS, then create cell to startup CELLSRV to complete cell configuration. If this is a manual installation, please stop and restart ExaWatcher to pick up newly installed binaries. You can run "/opt/oracle.ExaWatcher/ExaWatcher.sh --stop" and then "/opt/oracle.ExaWatcher/ExaWatcher.sh --fromconf" to stop and restart ExaWatcher. ######################################################### Logout and then re-login to use the new cell environment. #########################################################
