OpenEuler/almaLinux8 安装OSmind运维工具

一，载安装包

虚拟机中安装好openeuler2203或是almalinux8，中间安装有些坑需要注意

从官网下载安装包，上传到/opt目录下。

二 ，配置系统环境

1，python3.6不支持，有些pip安装的组件依赖能坑死人。

 #  yum remove  -y python36

这里我使用的python3.9

这里是 需要的组件 目录/etc/ITServiceTools/conf/requirements.txt。如果之前已经安装好了旧版的，可能需要单独uninstall，不然可以安装不了更高版本的。

下面是先给系统安装国内pgsql的源并禁用旧版本的。

   sudo yum install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm
   sed -i "s@https://download.postgresql.org/pub@https://mirrors.aliyun.com/postgresql@g" /etc/yum.repos.d/pgdg-redhat-all.repo 
  dnf -qy module disable postgresql
 

yum  install  -y "postgresql13-server" "postgresql"

ln -s /usr/bin/postgresql-13-setup /usr/bin/postgresql-setup 

#提前安装好pgsql并作个连接。

 #   yum install -y  python39*

 #   yum install -y vim net-tools unzip lrzsz dos2unix ntpdate

 
#  unzip ITServiceTools-1.0.0.zip 

2，解压主安装包后，找到 deploy.sh 中 get_os_name中的funciton中的内容，只保留下面的，不然安装提示系统报错

function get_os_name()
{
    local name
    name=$(grep -w NAME /etc/os-release | cut -d '"' -f 2)
    OS_NAME="openEuler${VERSION_ID}LTS"
    return 0
}

我这里数据库使用 pg13版本，与其它版本有些不同，所以deploy.sh 脚本内容作了一些修改，主要修改pg的命令与数据目录路径，具体看最后一节。

3，安装命令

上传安装包ITServiceTools-1.0.0.zip到主机/opt目录下进行解压，执行安装命令，

安装命令解析：

bash deploy.sh --postgresql --server_ip 192.168.137.122 --server_port 2233 --db_user osmind --db_passwd x2Euler@123

--postgresql           指定安装postgresql数据库，不指定默认使用sqlite作为ITServiceTools服务的数据库

--server_ip            设置ITServiceTools服务的IP
--server_port          设置ITServiceTools服务的端口号，即前端web页面管理端口
--db_user              用于ITServiceTools连接postgresql数据库的用户名
--db_passwd            用于ITServiceTools连接postgresql数据库的密码

安装过程如有报错，需要使用以下命令删除包：

 yum remove -y "postgresql-server" "postgresql"
 rm  -rf /usr/bin/postgresql-setup 
 rm -rf /var/lib/pgsql
 rpm -e ITServiceTools 

再重新执行安装命令。

4，报错解决方法

jango.db.utils.NotSupportedError: PostgreSQL 12 or later is required

可使用以下命令，给djiango降版本，然后再重新安装ITService Tools

pip uninstall django

pip install django==3.2.25
