+
+**部署集群**
+----
+
+### **1\.** **操作系统配置**
+
+配置HOSTS\*
+
+```
+cat >> etc/hosts <<EOF  
+10.10.10.101 opt01  
+10.10.10.102 opt02  
+10.10.10.103 opt03  
+10.10.10.104 opt04  
+10.10.10.105 opt05  
+EOF  
+```  
+
+关闭防火墙
+
+```
+systemctl stop firewalld.service   
+systemctl disable firewalld.service  
+```  
+
+关闭SELinux
+
+```
+sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' etc/selinux/config  
+setenforce 0  
+```  
+
+创建用户
+
+```
+mkdir data  
+useradd -d data/opentenbase -s bin/bash -m opentenbase  
+passwd opentenbase  
+```  
+
+配置ssh互信
+
+```
+su - opentenbase  
+ssh-keygen -t rsa  
+ssh-copy-id -i ~/.ssh/id_rsa.pub opt01  
+ssh-copy-id -i ~/.ssh/id_rsa.pub opt02  
+ssh-copy-id -i ~/.ssh/id_rsa.pub opt03  
+ssh-copy-id -i ~/.ssh/id_rsa.pub opt04  
+ssh-copy-id -i ~/.ssh/id_rsa.pub opt05  
+``` 
+
+安装依赖软件
+
+```
+rm -rf etc/yum.repos.d/CentOS-*  
+cat > etc/yum.repos.d/redhat.repo <<EOF  
+[CentOS]  
+name=CentOS  
+baseurl=https://mirrors.aliyun.com/centos-vault/centos/7/os/x86_64  
+enabled=1  
+gpgcheck=0  
+EOF  
+  
+yum -y install gcc make readline-devel zlib-devel openssl-devel uuid-devel bison flex git  
+``` 
+
+### **2\.** **数据库软件下载与安装**
+
+仅需在一个节点执行即可
+
+```
+su - opentenbase  
+git clone https://github.com/OpenTenBase/OpenTenBase  
+
+在下面地址下载最新安装包
+
+https://github.com/OpenTenBase/OpenTenBase/tags  
+
+tar -xvf OpenTenBase-2.6.0.tar.gz  
+  
+cd data/opentenbase/OpenTenBase-2.6.0/  
+chmod +x configure*  
+./configure --prefix=/data/opentenbase/install/opentenbase_bin_v2.0 --enable-user-switch --with-openssl --with-ossp-uuid CFLAGS=-g  
+make clean  
+make -sj  
+make install  
+chmod +x contrib/pgxc_ctl/make_signature  
+cd contrib  
+make -sj  
+make install  
+  
+配置环境变量（每个节点都需要执行）  
+
+cat >> ~/.bashrc <<EOF  
+export OPENTENBASE_HOME=/data/opentenbase/install/opentenbase_bin_v2.0  
+export PATH=\$OPENTENBASE_HOME/bin:\$PATH  
+export LD_LIBRARY_PATH=\$OPENTENBASE_HOME/lib:\$LD_LIBRARY_PATH  
+export LC_ALL=C  
+EOF  
+```  
+### **3\.** **配置集群**
+
+```

+cd data/opentenbase/pgxc_ctl

+### **4.** **分发软件**
+
+```
+pgxc_ctl  
+> deploy all  
+``` 
+
+<img src=../images/news-post-12-4.png class="img-fluid" /><br/>
+
+### **5\.** **启动数据库**
+
+```
+pgxc_ctl  
+> init all  
+``` 
+
+### **6\.** **查看集群状态**
+
+```
+pgxc_ctl  
+> monitor all  
+``` 
+
+<img src=../images/news-post-12-5.png class="img-fluid" /><br/>
+
+**访问数据库**
+---------
+
+```sql
+psql -h 10.10.10.101 -p 30004 -d postgres -U opentenbase
+select * from pgxc_node;
+```

+
+**总结**
+------
+
+整体来说OpenTenBase的安装过程还是比较快捷的。
+
+但是有几点需要记录一下：
+
+1.  使用RHEL8.10安装有点问题，不知道是操作还是其他的原因，回头再整一次
+
+2.  uuid-devel没有在标准iso和epel中，安装有点点麻烦
