1.環境說明

[omm@node1 bak]$ cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
[omm@node1 bak]$ lscpu
Architecture:          x86_64
說明:使用om工具需要python3，而centos7.6是python2，有網的情況直接yum install -y python3，無網則需要手動編譯Python3，https://docs.mogdb.io/zh/mogdb/v3.0/standard-installation

2.檢查環境

systemctl disable firewalld.service
systemctl stop firewalld.service
setenforce=0
sed -i '/^SELINUX=/c'SELINUX=disabled /etc/selinux/config

3.安裝基礎包

yum install -y libaio-devel 
yum install -y bzip2 libaio-devel flex bison ncurses-devel glibc-devel libxml2-devel patch redhat-lsb-core unzip gcc gcc-c++ perl openssl-devel libffi-devel libtool zlib-devel

4.規劃安裝目錄

mkdir -p /opt/software/mogdb 
cd /opt/software/mogdb
chmod -R  755  /opt/software/mogdb/
[root@node1 mogdb]# wget https://cdn-mogdb.enmotech.com/mogdb-media/3.0.1/MogDB-3.0.1-CentOS-x86_64.tar.gz

5 .編寫配置文件(單機)

[root@node1 mogdb]# cat clusterconfig.xml

            <PARAM name="backIp1" value="172.24.11.219"/>
            <PARAM name="sshIp1" value="172.24.11.219"/>

        </DEVICE>
    </DEVICELIST>
</ROOT>
