Local Repo
Pigsty是一个复杂的软件系统,为了确保系统的稳定,Pigsty会在初始化过程中从互联网下载所有依赖的软件包并建立本地Yum源。
所有依赖的软件总大小约1GB左右,下载速度取决于您的网络情况。尽管Pigsty已经尽量使用镜像源以加速下载,但少量包的下载仍可能受到防火墙的阻挠,可能出现非常慢的情况。您可以通过proxy_env
配置项设置下载代理以完成首次下载,或直接下载预先打包好的离线安装包。
建立本地Yum源时,如果{{ repo_home }}/{{ repo_name }}
目录已经存在,而且里面有repo_complete
的标记文件,Pigsty会认为本地Yum源已经初始化完毕,因此跳过软件下载阶段,显著加快速度。离线安装包即是把{{ repo_home }}/{{ repo_name }}
目录整个打成压缩包。

参数详解
repo_enabled
如果为true
(默认情况),执行正常的本地yum源创建流程,否则跳过构建本地yum源的操作。
repo_name
本地yum源的名称,默认为pigsty
,您可以改为自己喜欢的名称,例如pgsql-rhel7
等。
repo_address
本地yum源对外提供服务的地址,可以是域名也可以是IP地址,默认为yum.pigsty
。
如果使用域名,您必须确保在当前环境中该域名会解析到本地源所在的服务器,也就是元节点。
如果您的本地yum源没有使用标准的80端口,您需要在地址中加入端口,并与repo_port
变量保持一致。
您可以通过节点参数中的静态DNS配置来为环境中的所有节点写入Pigsty
本地源的域名,沙箱环境中即是采用这种方式来解析默认的yum.pigsty
域名。
repo_port
本地yum源使用的HTTP端口,默认为80端口。
repo_home
本地yum源的根目录,默认为www
。
该目录将作为HTTP服务器的根对外暴露。
repo_rebuild
如果为false
(默认情况),什么都不发生,如果为true
,那么在任何情况下都会执行Repo重建的工作。
repo_remove
在执行本地源初始化的过程中,是否移除/etc/yum.repos.d
中所有已有的repo?默认为true
。
原有repo文件会备份至/etc/yum.repos.d/backup
中。
因为操作系统已有的源内容不可控,建议强制移除并通过repo_upstreams
进行显式配置。
repo_upstream
所有添加到/etc/yum.repos.d
中的Yum源,Pigsty将从这些源中下载软件。
Pigsty默认使用阿里云的CentOS7镜像源,清华大学Grafana镜像源,PackageCloud的Prometheus源,PostgreSQL官方源,以及SCLo,Harbottle,Nginx, Haproxy等软件源。
