一，基本环境配置
01，hosts
cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.240 SHLPDBWX01 192.168.0.241 SHLPDBWX02 172.168.0.240 SHLPDBWX01-priv 172.168.0.241 SHLPDBWX02-priv 192.168.0.243 SHLPDBWX01-vip 192.168.0.244 SHLPDBWX02-vip 192.168.0.242 dgwxpdb dgwxpdb.localdomain
02，用户环境配置
groupadd –g 501 oinstall useradd oracle –u 500 –g oinstall echo 123456|passwd --stdin oracle
03，配置目录
cat .bash_profile PATH=$PATH:$HOME/bin ORACLE_BASE=/u01/app/oracle export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1 export ORACLE_SID=WXPDB01 export PATH=$PATH:$ORA_CRS_HOME/bin:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:. alias sqlplus='rlwrap sqlplus' # oracle sqlpls alias rman='rlwrap rman' # oracle rman alias ggsci='rlwrap ggsci' # oracle goldengate stty erase ^h export PATH 创建目录授予权限 mkdir /u01/app/oracle/product/10.2.0/db_1 -p chown -R oracle.oinstall /u01/ chmod -R 755 /u01/
04，磁盘配置
见https://www.cnblogs.com/kingle-study/p/10972214.html
05，配置参数
vi /etc/sysctl.conf kernel.core_uses_pid = 1 fs.file-max = 65536 fs.aio-max-nr = 1048576 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 kernel.shmmni = 4096 kernel.sem = 500 64000 100 128 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_tw_recycle = 1
vi /etc/security/limits.conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536
06，安装包检测
检测 rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH}) ' binutils compat-libstdc++ elfutils-libelf-devel elfutils-libelf-devel-static gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers kernel-headers ksh libaio libaio-devel libgcc libgomp libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel libXp
缺少的对应安装 10C的包可能有的需要i686
通过RPm包安装
07，配置互信
