• 关闭Slinux

[root@gaussdb-wyl ~]# vim /etc/selinux/config 
SELINUX=disabled
[root@gaussdb-wyl ~]# setenforce 0
[root@gaussdb-wyl ~]# getenforce 
Permissive
[root@gaussdb-wyl ~]# 

• 关闭防火墙

[root@gaussdb-wyl ~]# systemctl stop firewalld.service 
[root@gaussdb-wyl ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

• 创建安装用户和用户组

groupadd dbgrp
useradd -g dbgrp -d /home/omm -m -s /bin/bash omm
passwd omm

说明：设置omm用户密码

• 上传GaussDB 100安装包，并解压

[root@gaussdb-wyl soft]# pwd
/soft
[root@gaussdb-wyl soft]# ls -ltr

• 进入安装目录查看

[root@gaussdb-wyl soft]# cd GaussDB_100_1.0.1-DATABASE-CENTOS-64bit/
[root@gaussdb-wyl GaussDB_100_1.0.1-DATABASE-CENTOS-64bit]# ll

• 进入安装包解压目录，执行install.py脚本进行安装，看到如下表示成功！

[root@gaussdb-wyl GaussDB_100_1.0.1-DATABASE-CENTOS-64bit]# python install.py -U omm:dbgrp -R /gdb/gaussdb/app -D /gdb/gaussdb/data -C LSNR_ADDR=127.0.0.1,192.168.79.137 -C LSNR_PORT=1888 -C DATA_BUFFER_SIZE=200M -C SHARED_POOL_SIZE=100M -C TEMP_BUFFER_SIZE=100M

• 配置zengine.ini文件

[root@gaussdb-wyl cfg]# cat zengine.ini
LOG_BUFFER_SIZE = 64M
DBWR_PROCESSES = 8
LOG_BUFFER_COUNT = 8
SESSIONS = 1500
INSTANCE_NAME = zenith
LSNR_ADDR = 127.0.0.1,192.168.79.137
LSNR_PORT = 1888
ENABLE_SYSDBA_LOGIN = TRUE
SHARED_POOL_SIZE = 100M
TEMP_BUFFER_SIZE = 100M
DATA_BUFFER_SIZE = 200M
CONTROL_FILES = (/gdb/gaussdb/data/data/cntl1, /gdb/gaussdb/data/data/cntl2, /gdb/gaussdb/data/data/cntl3)

• OMM用户环境变量
  在安装完成后，会自动在OMM用户配置文件.bashrc下添加4个变量

[root@gaussdb-wyl cfg]# su - omm
Last login: Sat Dec 28 00:10:35 CST 2019 on pts/0
[omm@gaussdb-wyl ~]$ cat .bashrc 
# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions
export GSDB_HOME="/gdb/gaussdb/app"
export PATH="/gdb/gaussdb/app/bin":$PATH
export LD_LIBRARY_PATH="/gdb/gaussdb/app/lib":"/gdb/gaussdb/app/add-ons":$LD_LIBRARY_PATH
export GSDB_DATA="/gdb/gaussdb/data"

• 启动数据库（Zengine instance has already started）表示实例已经启动

[omm@gaussdb-wyl bin]$ pwd
/gdb/gaussdb/app/bin
[omm@gaussdb-wyl bin]$ ls -ltr

• 登录数据库

[omm@gaussdb-wyl bin]$ zsql sys/Changeme_123@127.0.0.1:1888
connected.
SQL> 
[omm@gaussdb-wyl bin]$ zsql / as sysdba
connected.
SQL> 
安装后默认密码为"Changeme_123"

• 修改数据库SYS密码

ALTER USER SYS IDENTIFIED BY wangyl_2019;

• 查询数据库基本信息

SQL> select dbid,name,status,open_status from dv_database;

DBID         NAME                             STATUS               OPEN_STATUS
