## 编译安装openGuass 3.0.0

### 1. 环境检查
#### 1.1 检查OS版本

```c
openGauss支持的操作系统：

CentOS 7.6（x86 架构）
openEuler-20.03-LTS（aarch64 架构）
openEuler-20.03-LTS（x86 架构）
Kylin-V10（aarch64 架构）
```

[root@og3 ~]# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core)

#### 1.2 修改主机名及/etc/hosts
hostnamectl set-hostname og
cat>>/etc/hosts<<EOF
192.168.137.129    og
EOF

1.3.	检查防火墙和selinux
在RHEL 7中，防火墙firewalld取代了iptables
 
```shell
systemctl status firewalld
systemctl stop firewalld
systemctl disable firewalld
systemctl is-enabled firewalld
/bin/sed -i s/SELINUX=enforcing/SELINUX=disabled/ /etc/selinux/config
cat /etc/selinux/config|grep SELINUX=
setenforce 0
```

#### 1.3 配置yum源并安装依赖包
上传操作系统iso到/soft目录
[root@og3 ~]# mkdir -p /soft
[root@og3 ~]# cd /soft
[root@og3 soft]# ls -ltr
total 4481024
-rw-r--r--. 1 root root 4588568576 Apr  8  2019 CentOS-7-x86_64-DVD-1810.iso

cd /soft
mv CentOS-7-x86_64-DVD-1810.iso yum.iso
mount -o loop /soft/yum.iso /mnt
mkdir -p /etc/yum.repos.d/bak/
mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/
cat>>/etc/yum.repos.d/rhel-source.repo <<EOF
[rhel-oracle-lib]
name=oracle
baseurl=file:///mnt
enabled=1
gpgcheck=0
EOF
yum clean all
yum makecache
yum list

yum -y install libaio-devel flex bison ncurses-devel glibc-devel patch redhat-lsb readline-devel unzip dos2unix vim git wget lrzsz net-tools bzip2 gcc tree zlib*

#### 1.4 设置字符集参数
cat>>/etc/profile<<EOF
export LANG=zh_CN.UTF-8
EOF

#### 1.5 设置时区和时间
[root@og ~]# timedatectl set-timezone Asia/Shanghai
[root@og ~]# timedatectl status

使用date -s命令将各主机的时间设置为统一时间，举例如下。

date -s "Sat Sep 27 16:00:07 CST 2020"

#### 1.6 关闭HISTORY记录
cat>>/etc/profile<<EOF
HISTSIZE=0
EOF

2、安装Python3官方
建议安装Python3.6
cd /soft/
wget -c https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
mkdir -p /usr/local/python3.6.5
tar -zxvf Python-3.6.5.tgz
cd Python-3.6.5
./configure --prefix=/usr/local/python3.6.5 --enable-shared CFLAGS=-fPIC && make && make install
rm -f /usr/bin/python
ln -s /usr/local/python3.6.5/bin/python3 /usr/bin/python
ln -s /usr/local/python3.6.5/bin/python3 /usr/bin/python3
ln -s /usr/local/python3.6.5/bin/pip3 /usr/bin/pip3

cp /usr/local/python3.6.5/lib/libpython3.6m.so.1.0 /usr/lib64/
python -V

### 3. 下载软件包
cd /soft/
git clone https://gitee.com/opengauss/openGauss-server.git openGauss-server -b 3.0.0
git clone https://gitee.com/opengauss/openGauss-OM.git
wget -c https://opengauss.obs.cn-south-1.myhuaweicloud.com/3.0.0/openGauss-third_party_binarylibs.tar.gz

### 4. 一键式脚本编译
tar -xf openGauss-third_party_binarylibs.tar.gz
mv openGauss-third_party_binarylibs binarylibs

cd openGauss-server/
sh build.sh -m debug -3rd /soft/binarylibs -pkg

显示如下内容，表示编译成功。
```c
success!

生成的安装包会存放在./output目录下。
编译和打包日志为：./build/script/makemppdb_pkg.log。

```

### 4. openGauss-OM编译
cd /soft/openGauss-OM
chmod +x build.sh
export BINARYLIBS_PATH=/soft/binarylibs  (这里填写前面的第三方软件包解压后的目录)
./build.sh -3rd $BINARYLIBS_PATH

显示以下内容，表示 Gauss-OM编译成功：
```c
ROOT_DIR: /soft/binarylibs
Everything is ready.
success!
```

### 5. 软件安装
#### 5.1 程序下载及解压
mkdir -p /opt/software/openGauss
mv /soft/openGauss-server/output/* /opt/software/openGauss/
mv /soft/openGauss-OM/package/* /opt/software/openGauss/
chmod 755 -R /opt/software
cd /opt/software/openGauss/

tar -jxf openGauss-3.0.0-CentOS-64bit.tar.bz2
tar -xf openGauss-3.0.0-CentOS-64bit-om.tar.gz

#### 5.2 创建用户
groupadd dbgrp
useradd omm -g dbgrp
echo "Root_1234"|passwd --stdin omm

#### 5.3 生成配置文件 
cat >> /opt/software/openGauss/cluster_config.xml <<-EOF
<?xml version="1.0" encoding="UTF-8"?>
<ROOT>
    
    <CLUSTER>
        
        <PARAM name="clusterName" value="dbCluster" />
        
        <PARAM name="nodeNames" value="`hostname`" />
        
        <PARAM name="gaussdbAppPath" value="/opt/huawei/install/app" />
        
        <PARAM name="gaussdbLogPath" value="/var/log/omm" />

        <PARAM name="corePath" value="/opt/huawei/corefile" />
        
        <PARAM name="backIp1s" value="`cat /etc/hosts|grep \`hostname\`|awk '{print $1}'|head -1`"/> 
    </CLUSTER>
    
    <DEVICELIST>
        
        <DEVICE sn="node1_hostname">
            
            <PARAM name="name" value="`hostname`"/>
            
            <PARAM name="azName" value="AZ1"/>
            <PARAM name="azPriority" value="1"/>
            
            <PARAM name="backIp1" value="`cat /etc/hosts|grep \`hostname\`|awk '{print $1}'|head -1`"/>
            <PARAM name="sshIp1" value="`cat /etc/hosts|grep \`hostname\`|awk '{print $1}'|head -1`"/>
               
	    
	    <PARAM name="dataNum" value="1"/>
	    <PARAM name="dataPortBase" value="15400"/>
	    <PARAM name="dataNode1" value="/opt/huawei/install/data/dn"/>
            <PARAM name="dataNode1_syncNum" value="0"/>
        </DEVICE>
    </DEVICELIST>
</ROOT>
EOF

#### 5.4 初始化安装环境
cd /opt/software/openGauss/script
./gs_preinstall -U omm -G dbgrp -L -X /opt/software/openGauss/cluster_config.xml

### 6. 执行安装
su - omm
gs_install -X /opt/software/openGauss/cluster_config.xml

### 7. 初始化数据库
[root@og openGauss]# su - omm

#### 7.1 检查数据库状态

[omm@og ~]$ gs_om -t status

```shell
执行如下命令检查数据库状态是否正常，“cluster_state ”显示“Normal”表示数据库可正常使用。
```

[omm@og ~]$ gsql -d postgres -p 15400
openGauss=# CREATE DATABASE mydb WITH ENCODING 'GBK' template = template0;
CREATE DATABASE
openGauss=#
