首先在edelivery中下载Oracle Linux 8.0
然后就默认安装系统
环境准备工具目前不支持OL8，所以需要手动安装，首先设置内核参数，在/etc/sysctl.conf追加
[root@localhost ~]# cat /etc/sysctl.conf |grep -v ^#|grep -v ^$ fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 kernel.panic_on_oops = 1 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 net.ipv4.conf.all.rp_filter = 2 net.ipv4.conf.default.rp_filter = 2 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500 [root@localhost ~]#
sysctl -p使参数生效
然后/etc/security/limits.d/oracle-database-preinstall-19c.conf中添加
[root@localhost limits.d]# cat /etc/security/limits.d/oracle-database-preinstall-19c.conf oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 16384 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 32768 oracle hard memlock 134217728 oracle soft memlock 134217728 [root@localhost limits.d]#
安装依赖软件
dnf install -y bc binutils compat-libstdc -33 elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc glibc-devel ksh libaio libaio-devel libXrender libXrender-devel libX11 libXau libXi libXtst libgcc librdmacm-devel libstdc libstdc -devel libxcb make net-tools nfs-utils Python3 python3-configshell python3-rtslib python3-six targetcli smartmontools sysstat unixODBC libnsl libnsl.i686 libnsl2 libnsl2.i686
创建用户组和用户
[root@localhost limits.d]# groupadd -g 1001 oinstall [root@localhost limits.d]# groupadd -g 1002 dba [root@localhost limits.d]# groupadd -g 1003 oper [root@localhost limits.d]# useradd -u 1001 -g oinstall -G dba,oper oracle [root@localhost limits.d]# passwd oracle Changing password for user oracle. New password: BAD PASSWORD: The password is shorter than 8 characters Retype new password: passwd: all authentication tokens updated successfully. [root@localhost limits.d]#
创建目录
[root@localhost ~]# mkdir -p /u01/app/oraInventory [root@localhost ~]# mkdir -p /u01/app/oracle/product/19.3.0/dbhome_1 [root@localhost ~]# chown -R oracle: /u01/app/oraInventory [root@localhost ~]# chown -R oracle: /u01/app/oracle [root@localhost ~]# su - oracle [oracle@localhost db]$ unzip -q /stage/db/V982063-01.zip -d /u01/app/oracle/product/19.3.0/dbhome_1/ [oracle@localhost db]$
开始安装，注意版本兼容问题要先设置环境变量export CV_ASSUME_DISTID=RHEL7.6

静默安装数据库,df -h先看看内存够不够,不够就调整参数大小或者mount -o remount,size=4G /dev/shm
