ubuntu ansible 安装opengauss

安装OpenGauss的步骤如下：

1. 首先需要在Ubuntu中安装Ansible。使用以下命令安装Ansible：

   sudo apt update
   sudo apt install ansible

2. 然后需要创建Ansible的inventory文件，用于指定需要安装OpenGauss的主机。inventory文件的格式如下：

   [opengauss]
   opengauss-server ansible_host=server_ip_address

其中，`opengauss-server`是主机名，`server_ip_address`是主机的IP地址。

3. 接下来需要编写Ansible playbook，用于安装OpenGauss。以下是一个简单的playbook示例：

   ---
   - hosts: opengauss
     become: yes
     vars:
       opengauss_version: "2.0.0"
       opengauss_install_dir: "/usr/local/opengauss"
       opengauss_data_dir: "/var/lib/opengauss/data"
       opengauss_port: 5432
       opengauss_charset: "UTF8"
       opengauss_init_password: "opengauss"
     tasks:
     - name: "Create OpenGauss installation directory"
       file:
         path: "{{ opengauss_install_dir }}"
         state: directory

     - name: "Install OpenGauss dependencies"
       apt:
         name: ["libreadline-dev", "zlib1g-dev", "libossp-uuid-dev", "libxml2-dev", "libxslt-dev"]
         state: present

     - name: "Download OpenGauss package"
       get_url:
         url: "https://opengauss.obs.cn-north-4.myhuaweicloud.com/2.0.0/opengauss-{{ opengauss_version }}-linux-x86_64.tar.gz"
         dest: "/tmp/opengauss-{{ opengauss_version }}-linux-x86_64.tar.gz"

     - name: "Extract OpenGauss package"
       unarchive:
         src: "/tmp/opengauss-{{ opengauss_version }}-linux-x86_64.tar.gz"
         dest: "{{ opengauss_install_dir }}"
         copy: no

     - name: "Create OpenGauss data directory"
       file:
         path: "{{ opengauss_data_dir }}"
         state: directory

     - name: "Initialize OpenGauss database"
       command: "{{ opengauss_install_dir }}/bin/gs_initdb -D {{ opengauss_data_dir }} -E {{ opengauss_charset }} --nodename=OpenGauss --locale=C --auth=trust --encoding={{ opengauss_charset }}"

     - name: "Start OpenGauss database"
       command: "{{ opengauss_install_dir }}/bin/gs_ctl start -D {{ opengauss_data_dir }} -o \"-p {{ opengauss_port }}\""

     - name: "Change OpenGauss password"
       command: "{{ opengauss_install_dir }}/bin/gsql -d postgres -p {{ opengauss_port }} -c \"alter user postgres with password '{{ opengauss_init_password }}';\""

在playbook中，我们指定了OpenGauss的版本、安装路径、数据目录等信息。然后依次执行了创建安装目录、安装依赖、下载OpenGauss包、解压OpenGauss包、创建数据目录、初始化数据库、启动数据库和修改密码等任务。

4. 运行playbook，执行安装OpenGauss的操作。

   ansible-playbook -i inventory_file install_opengauss.yml

以上是在Ubuntu上使用Ansible安装OpenGauss的简单步骤和示例。如果您有任何问题，请随时提出。
