一、环境准备

节点类别	主机名	IP	端口
主节点	ptkmog1	192.168.3.63	15400
备节点1	ptkmog2	192.168.3.64	15400
备节点2	ptkmog3	192.168.3.65	15400

二、关闭防火墙和透明大页

1、修改操作系统配置
1) 关闭 SELINUX
修改 /etc/selinux/config文件中的“SELINUX”值为“disabled”

2) 关闭防火墙并禁止开机重启
systemctl disable firewalld.service
systemctl stop firewalld.service

3)  修改主机名
在每个服务器节点修改hostname,以主机为例：
hostnamectl set-hostname ptkmog1
另外两台备机分别设置为ptkmog2和ptkmog3

4) 关闭透明大页
echo never > /sys/kernel/mm/transparent_hugepage/enabled

复制

三、安装操作系统依赖包

3.1配置yum，安装系统包

mount /dev/cdrom /media/cdrom

vi /etc/yum.repos.d/oracle.repo
[Server]
name=Red Hat Enterprise Linux $releasever Beta - $basearch - Source
baseurl=file:///media/cdrom
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

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
yum install -y libaio-devel gcc gcc-c++ zlib-devel expect

3.2安装Python3（每个节点）root执行


# 解压并安装python3
[root@mogdb1 ~]# cd /enmo/soft
[root@mogdb1 soft]# tar -zxvf python3-rpm.tar.gz
# 配置yum源
[root@mogdb1 ~]# cat > /etc/yum.repos.d/enmo.repo << EOF
[Server]
name=Server
baseurl=file:///media/cdrom
enabled=yes
gpgcheck=0

[python3]
name=python3
baseurl=file:///enmo/soft/python3-rpm
enabled=yes
gpgcheck=0
EOF
# 执行yum安装
[root@mogdb1 ~]# yum clean all
[root@mogdb1 ~]# yum install python3 python3-devel -y
# 修改软链接
[root@mogdb1 ~]# rm -f /usr/bin/python
[root@mogdb1 ~]# ln -s /usr/bin/python3 /usr/bin/python
# 查看版本，确认安装成功
[root@mogdb1 ~]# python -V
Python 3.6.8
# 全词匹配替换，python3安装后’yum’命令执行会报错，需要修改以下配置
[root@mogdb1 ~]# sed -i "s:\<python\>:python2:g" /usr/bin/yum
[root@mogdb1 ~]# sed -i "s:\<python\>:python2:g" /usr/libexec/urlgrabber-ext-down

四、ptk安装（每个节点）root执行

[root@ptkmog1 ptk]# pwd
/opt/ptk
[root@ptkmog1 ptk]# wget https://cdn-mogdb.enmotech.com/ptk/latest/ptk_linux_x86_64.tar.gz
[root@ptkmog1 ptk]# tar xf ptk_linux_x86_64.tar.gz
[root@ptkmog1 ptk]# ls -l
[root@ptkmog1 opt]# ll

五、安装mogdb（仅主节点）root执行：

5.1 准备配置文件

global:
    cluster_name: mogdb_cluster
    user: omm
    group: omm
    base_dir: /opt/mogdb
db_servers:
    - host: 192.168.3.63
      db_port: 15400
      role: primary
      ssh_option:
        port: 22
        user: root
        password: pTk6ZGFmMTk1Yjg8QD1CPUU/QnJ1VjhaVEliZEtvT0pXcnhEQk5WN2pnUHFDeXp3bGs1T09mSkRUdWtva00=
    - host: 192.168.3.64
      db_port: 15400
      role: standby
      ssh_option:
        port: 22
        user: root
        password: pTk6ZGFmMTk1Yjg8QD1CPUU/QmVUTTJiUF9GT3BjNUN6bDc2QUNhWnlMOHkwRkRseE9NbWZFcjdTaVd2NkE=
    - host: 192.168.3.65
      db_port: 15400
      role: standby
      ssh_option:
        port: 22
        user: root
        password: pTk6ZGFmMTk1Yjg8QD1CPUU/QmFqODVlNk9FMmFfaUxsQ3d0dmlZNkEtSU55dktHbjJOZDBXWUFheU9RTU0=

#####注意配置文件中的主机名和ip

复制

确保输出的检查结果均为 OK 或者 Warning 。
如果有 Abnormal 的检查项出现，PTK默认会自动生成一个 root_fix_os 前缀的 Shell 脚本，您可以通过执行该 Shell 脚本来尝试自动修复异常的检查项。
大部分情况下都是可以自动修复的，如果出现特殊情况，PTK 没有兼容到，需您根据日志提示手动修正。

5.3 执行安装

六、安装验证

安装完成后，可使用omm用户通过“gsql -d postgres -p 26000 -r”命令连接MogDB数据库，其中“-p 26000”为数据库端口号，请根据实际情况替换。键入“\copyright”可查看版权信息

bash: gsql: command not found...
[root@ptkmog1 opt]# su - omm
[omm@ptkmog1 ~]$ gsql -d postgres -p 15400 -r
gsql ((MogDB 3.0.1 build 1a363ea9) compiled at 2022-08-05 17:31:04 commit 0 last mr  )
Non-SSL connection (SSL connection is recommended when requiring high-security)
Type "help" for help.

注：用gs_ctl滚动升级，先升级备库，后升主库。升级之后 ,发现处于 Need repair(WAL segment removed) 状态。
