centos7上安装oracle 12c

环境

VMware Workstation11+Centos7_64+Oracle12c_64

1.关闭防火墙

root>systemctl stop firewalld.service

root>systemctl disable firewalld.service

2.安装必须软件包

root>yum -y install binutils compat-libcap gcc gcc-c++ glib2-devel glibc ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libX11 libXau libxcb libXext libXtst make sysstat

3.安装调用图形化需要的包

root>yum -y install unixODBC unixODBC-devel xterm

4.添加用户及相关目录

root>groupadd oinstall

root>groupadd dba

root>useradd -g oinstall -G dba oracle

root>passwd oracle

root>id oracle

uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)

root>mkdir -p /u01/app/oracle/product/12.1.0/db_1

root>mkdir -p /u01/app/oraInventory

root>chown -R oracle:oinstall /u01/app

root>chmod -R 775 /u01/app

5.配置内核参数

root>vi /etc/sysctl.conf

# System default settings live in /usr/lib/sysctl.d/00-system.conf.

# To override those settings, enter new settings here, or in an /etc/sysctl.d/.conf file

#

# For more information, see sysctl.conf(5) and sysctl.d(5).

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 4294967295

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

root>sysctl -p

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 4294967295

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

–修改系统限制

root>vi /etc/security/limits.conf

# End of file

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

root>vi /etc/pam.d/login

session required /lib/security/pam_limits.so

session required pam_limits.so

root>vi /etc/profile

if [ USER=“oracle”];thenif[SHELL = “/bin/ksh” ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

fi

6.切换到oracle用户下，配置环境变量

root>su - oracle

oracle>vi .bash_profile

ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
ORACLE_SID=lytzats
PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH

oracle>xhost +

access control disable, clients can connect from any host

oracle>./runInstaller

中文乱码问题

如果你采用的centos7选择中文模式，在安装oracle12c的时候会出现乱码

解决：

oracle12c安装乱码解决

1. 进入安装包目录下找到filegroup2.jar文件：

/home/oracle/soft/database/stage/Components/oracle.jdk/1.6.0.75.0/1/DataFiles/filegroup2.jar

2. 拷贝到Windows环境下用360压缩打开

3. 建立fallback文件夹,把下载的字符集zysong.ttf拷贝进去

4. 保存，覆盖掉原来的文件

7.图形化安装步骤

这里我们选择安装仅安装数据库软件，在后面我们需要手动创建Oracle实例。

8.创建数据库实例

oracle>dbca



















在这里可以选择配置数据库的字符集。

9.配置监听
