互信为了方便后续操作，建议配置opentenbase机器间的 SSH 互信：

[opentenbase]
#切换opentenbase用户
su - opentenbase
# 192.168.2.136生成 SSH 密钥对
ssh-keygen -t rsa
# 将公钥复制到其他节点

**6.3 配置opentenbase环境变量**

集群所有机器都需要配置

```
[opentenbase]
$ vim ~/.bashrc
export OPENTENBASE_HOME=/data/opentenbase/install/opentenbase_bin_v2.6
export PATH=$OPENTENBASE_HOME/bin:OPENTENBASEHOME/bin:$PATH
export LD_LIBRARY_PATH=$OPENTENBASE_HOME/lib:OPENTENBASEHOME/lib:${LD_LIBRARY_PATH}
export LC_ALL=C
```

**6.4 配置root环境变量**

集群所有机器都需要配置,把opentenbase用户的$PATH环境变量添加到 etc/environment

cat /etc/environment
PATH=/data/opentenbase/install/opentenbase_bin_v2.6/bin:/data/opentenbase/.local/bin:/data/opentenbase/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin
```

**6.5 初始化pgxc\_ctl.conf文件**

![](https://oss-emcsprod-public.modb.pro/image/auto/modb_20241030_c20d75d0-9694-11ef-a88b-fa163eb4f6be.png)
```
[opentenbase]
mkdir /data/opentenbase/pgxc_ctl
cd /data/opentenbase/pgxc_ctl
vim pgxc_ctl.conf
```

如下，是结合上文描述的IP，端口，数据库目录，二进制目录等规划来写的pgxc\_ctl.conf文件。

pgxc\_ctl.conf配置如下：

**6.6 分发二进制包**

在一个节点上配置好配置文件后，使用 pgxc\_ctl 工具将二进制包部署到所有节点：
