Oracle笔记（1）19c databse安装

一、环境

操作系统: CentOs7.6_64
安装源： Oracle Database 19.3.0.0.0 for Linux x86-64.zip
主机名： server
IP地址： 192.168.10.131

二、过程

参考：https://oracle-base.com/articles/19c/oracle-db-19c-installation-on-oracle-linux-7

2.1 准备阶段

1.关闭防火墙
[root@server ~]# systemctl stop firewalld.service
[root@server ~]# systemctl disable firewalld.service
[root@server ~]# systemctl status firewalld.service

2.关闭selinux
[root@server ~]# setenforce 0                  #临时设置SELinux 成为permissive模式， 1为enforcing模式
#[root@server ~]# setenforce Permissive        #或者
[root@server ~]# sed -i "s/^SELINUX=.*/SELINUX=Permissive/" /etc/selinux/config    #重启生效

3.修改hosts文件
[root@server ~]# cat >> /etc/hosts <<'EOF'

#add for oracle 
192.168.10.131 server
EOF

4.修改内核参数文件，添加内容
# Add the following lines to the "/etc/sysctl.conf" file, or in a file called "/etc/sysctl.d/98-oracle.conf".

[root@server ~]# cat >>/etc/sysctl.conf <<'EOF'

# add for oracle by me
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
EOF
[root@server ~]# /sbin/sysctl -p     #重启生效

5.修改vi /etc/security/limits.conf
#linux资源限制配置文件是/etc/security/limits.conf；限制用户进程的数量对于linux系统的稳定性非常重要。limits.conf文件限制着用户可以使用的最大文件数，最大线程，最大内存等资源使用量。
#oracle base写的/etc/security/limits.d/oracle-database-preinstall-19c.conf，操作系统为oracle linux。
[root@server ~]# cat >>/etc/security/limits.conf <<'EOF'

#add for oracle by me
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
EOF

6.安装必要的包
[root@server ~]# yum install -y bc binutils compat-libcap1 compat-libstdc++-33 dtrace-utils elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc glibc-devel ksh
yum install -y libaio libaio-devel libdtrace-ctf-devel  libXrender  libXrender-devel libX11 libXau  libXi libXtst libgcc librdmacm-devel  libstdc++ libstdc++-devel 
yum install -y libxcb make net-tools   nfs-utils python python-configshell python-rtslib  python-six targetcli smartmontools sysstat
yum install gcc-c++*

#yum install -y dtrace-modules
#yum install -y dtrace-modules-headers
#yum install -y dtrace-modules-provider-headers

# Added by me.
yum install -y unixODBC

7.创建用户和组
[root@server ~]# groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
#groupadd -g 54324 backupdba
#groupadd -g 54325 dgdba
#groupadd -g 54326 kmdba
#groupadd -g 54327 asmdba
#groupadd -g 54328 asmoper
#groupadd -g 54329 asmadmin
#groupadd -g 54330 racdba

useradd -u 54321 -g oinstall -G dba,oper oracle

[root@server ~]# passwd oracle           #修改oracle密码

8.创建安装目录
[root@server ~]# mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1
mkdir -p /u02/oradata
chown -R oracle:oinstall /u01 /u02
chmod -R 775 /u01 /u02                        #u01放软件  u02放数据文件

9.创建设置oracle 环境变量脚本
[root@server ~]# mkdir /home/oracle/scripts
[root@server ~]# cat > /home/oracle/scripts/setEnv.sh <<EOF
# Oracle Settings
export TMP=/tmp
export TMPDIR=$TMP

export ORACLE_HOSTNAME=server
export ORACLE_UNQNAME=cdb1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1
export ORA_INVENTORY=/u01/app/oraInventory
export ORACLE_SID=cdb1
export PDB_NAME=pdb1
export DATA_DIR=/u02/oradata

export PATH=/usr/sbin:/usr/local/bin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
EOF
[root@server ~]# chmod +x /home/oracle/scripts/setEnv.sh 
[root@server ~]# echo ". /home/oracle/scripts/setEnv.sh" >> /home/oracle/.bash_profile

10.将安装源解压至ORACLE_HOME

[root@server ~]# unzip /root/Oracle Database 19.3.0.0.0 for Linux x86-64.zip -d /u01/app/oracle/product/19.0.0/dbhome_1
[root@server ~]# chown -R oracle:oinstall /u01 /u02          #在root用户解压，需要修改文件权限
[root@server ~]# chmod -R 775 /u01 /u02                        #u01放软件  u02放数据文件

2.2 安装数据库软件

1.启动安装
[root@server ~]# su - oracle
[oracle@server ~]$ cd $ORACLE_HOME


# 图形化安装
[oracle@server dbhome_1]$ ./runInstaller

# 静默安装
[oracle@server dbhome_1]$ ./runInstaller -ignorePrereq -waitforcompletion -silent

2.4 创建数据库启动、停止脚本

参考：https://oracle-base.com/articles/linux/automating-database-startup-and-shutdown-on-linux

#修改/etc/oratab
