CentOS8.2同步阿里云Ceph镜像到本地,本地搭建ceph仓库

测试环境介绍

1、安装依赖服务

dnf -y install  yum-utils createrepo 

2、下载阿里云镜像cepo.repo文件

[root@ceph ceph]# cat /etc/yum.repos.d/ceph.repo [ceph] name=ceph baseurl=http://mirrors.aliyun.com/ceph/rpm-nautilus/el8/x86_64/ gpgcheck=0 priority=1  [ceph-noarch] name=ceph-noarch baseurl=http://mirrors.aliyun.com/ceph/rpm-nautilus/el8/noarch/ gpgcheck=0 priority=1  [ceph-source] name=ceph-source baseurl=http://mirrors.aliyun.com/ceph/rpm-nautilus/el8/SRPMS gpgcheck=0 priority=1 

3、刷新缓存，元数据缓存建立

dnf clean all dnf makecache dnf repolist 

4、同步镜像到本地

reposync -r base reposync -r extras reposync -r updates   [root@yumserver /]# mkdir -p /data/ceph/ceph [root@yumserver /]# reposync -p /data/ceph/ceph -n --repoid=ceph ceph                                                                              9.7 kB/s | 1.5 kB     00:00     (1/55): ceph-14.2.15-0.el8.x86_64.rpm                                              87 kB/s | 6.3 kB     00:00     (2/55): ceph-base-14.2.15-0.el8.x86_64.rpm                                        9.5 MB/s | 5.4 MB     00:00     (3/55): ceph-common-14.2.15-0.el8.x86_64.rpm                                      6.5 MB/s |  20 MB     00:02     (4/55): ceph-debugsource-14.2.15-0.el8.x86_64.rpm                                 5.8 MB/s | 9.1 MB     00:01     (5/55): ceph-fuse-14.2.15-0.el8.x86_64.rpm                                        192 kB/s | 593 kB     00:03     (6/55): ceph-base-debuginfo-14.2.15-0.el8.x86_64.rpm                              8.2 MB/s | 103 MB     00:12     (7/55): ceph-mds-14.2.15-0.el8.x86_64.rpm                                         6.3 MB/s | 2.0 MB     00:00     (8/55): ceph-fuse-debuginfo-14.2.15-0.el8.x86_64.rpm                              996 kB/s |  12 MB     00:12     (9/55): ceph-mds-debuginfo-14.2.15-0.el8.x86_64.rpm                               9.2 MB/s |  69 MB     00:07     (10/55): ceph-mgr-14.2.15-0.el8.x86_64.rpm                                        2.8 MB/s | 1.6 MB     00:00     (11/55): ceph-mon-14.2.15-0.el8.x86_64.rpm                                        4.7 MB/s | 4.5 MB     00:00     (12/55): ceph-mgr-debuginfo-14.2.15-0.el8.x86_64.rpm                              6.4 MB/s |  36 MB     00:05       [root@yumserver /]# mkdir -p /data/ceph/cephnoarch [root@yumserver /]# reposync -p /data/ceph/cephnoarch -n --repoid=ceph-noarch ceph-noarch                                                                        10 kB/s | 1.5 kB     00 (1/8): ceph-grafana-dashboards-14.2.15-0.el8.noarch.rpm                           145 kB/s |  24 kB     00 (2/8): ceph-mgr-diskprediction-cloud-14.2.15-0.el8.noarch.rpm                     235 kB/s |  41 kB     00 (3/8): ceph-mgr-k8sevents-14.2.15-0.el8.noarch.rpm                                198 kB/s |  23 kB     00 (4/8): ceph-mgr-diskprediction-local-14.2.15-0.el8.noarch.rpm                     4.4 MB/s | 1.1 MB     00 (5/8): ceph-mgr-rook-14.2.15-0.el8.noarch.rpm                                     120 kB/s |  15 kB     00 (6/8): ceph-release-1-1.el8.noarch.rpm                                             67 kB/s | 7.2 kB     00 (7/8): ceph-mgr-ssh-14.2.15-0.el8.noarch.rpm                                       95 kB/s |  16 kB     00 (8/8): ceph-mgr-dashboard-14.2.15-0.el8.noarch.rpm                                2.5 MB/s | 3.7 MB     00  [root@yumserver /]# mkdir -p /data/ceph/cephsource [root@yumserver /]# reposync -p /data/ceph/cephsource -n --repoid=ceph-source ceph-source                                                               16 kB/s | 1.5 kB     00:00     (1/2): ceph-release-1-1.el8.src.rpm                                       42 kB/s | 7.2 kB     00:00     (2/2): ceph-14.2.15-0.el8.src.rpm                                         17 MB/s | 101 MB     00:05     [root@yumserver /]#     

5、创建YUM仓库

[root@yumserver ceph]# createrepo -pdo /data/ceph/ceph/ceph /data/ceph/ceph/ceph Directory walk started Directory walk done - 55 packages Temporary output repo path: /data/ceph/ceph/ceph/.repodata/ Preparing sqlite DBs Pool started (with 5 workers) Pool finished [root@yumserver ceph]#     [root@yumserver ceph-noarch]# createrepo -pdo  /data/ceph/cephnoarch/ceph-noarch /data/ceph/cephnoarch/ceph-noarch Directory walk started Directory walk done - 8 packages Temporary output repo path: /data/ceph/cephnoarch/ceph-noarch/.repodata/ Preparing sqlite DBs Pool started (with 5 workers) Pool finished  [root@yumserver ceph-source]# createrepo -pdo /data/ceph/cephsource/ceph-source /data/ceph/cephsource/ceph-source Directory walk started Directory walk done - 2 packages Temporary output repo path: /data/ceph/cephsource/ceph-source/.repodata/ Preparing sqlite DBs Pool started (with 5 workers) Pool finished      

6、安装nginx，搭建本地Web服务器

[root@yumserver /]#  dnf -y install nginx  在/etc/nginx/conf.d/下面创建repos.conf配置文件  [root@ceph ceph-source]# cat  /etc/nginx/conf.d/repos.conf server {     listen        80;     server_name   _;      # 404 错误页面重定向配置     error_page  404  /404.html;      # 50x 错误页面重定项配置     error_page   500 503 504  /50x.html;      error_log    /var/log/nginx/repos_error.log;     access_log   /var/log/nginx/repos_access.log;      root /data/ceph/;      location / {         autoindex on;     }      location = /50x.html {         root   /usr/share/nginx/html;     }      location = /404.html {         root   /usr/share/nginx/html;     } }   修改 /etc/nginx/nginx.conf 注释掉nginx默认的80端口服务： #    server { #        listen       80 default_server; #        listen       [::]:80 default_server; #        server_name  _; #        root         /usr/share/nginx/html;  #        root         /cephyum;          # Load configuration files for the default server block. #        include /etc/nginx/default.d/*.conf;  #        location / { #        }  #        error_page 404 /404.html; #            location = /40x.html { #        }  #        error_page 500 502 503 504 /50x.html; #            location = /50x.html { #        } #    }   重启nginx服务或让nginx重新加载配置 systemctl restart nginx.service #或 systemctl reload nginx.service 

7、修改ceph YUM仓库配置

登录到ceph主机：192.168.6.159  [root@ceph ceph]# cat /etc/yum.repos.d/ceph.repo [ceph] name=ceph baseurl=http://192.168.6.178/ceph/ceph/ gpgcheck=0 priority=1  [ceph-noarch] name=ceph-noarch baseurl=http://192.168.6.178/cephnoarch/ceph-noarch/ gpgcheck=0 priority=1  [ceph-source] name=ceph-source baseurl=http://192.168.6.178/cephsource/ceph-source/ gpgcheck=0 priority=1   #####################刷新缓存 dnf clean all dnf makecache dnf repolist  

8、客户端安装ceph测试部署

#!/bin/bash #ceph一键部署脚本 #for Centos7 #1.disable iptables&selinux   echo -n "正在配置iptables防火墙……" systemctl stop firewalld > /dev/null 2>&1 systemctl disable firewalld  > /dev/null 2>&1 if [ $? -eq 0 ];then echo -n "Iptables防火墙初始化完毕！" fi   echo -n "正在关闭SELinux……" setenforce 0 > /dev/null 2>&1 sed -i '/^SELINUX=/s/=.*/=disabled/' /etc/selinux/config if [ $? -eq 0 ];then         echo -n "SELinux初始化完毕！" fi #2.set hostname as ceph##   HOSTNAME=ceph hostnamectl set-hostname ceph IP=`ip route |grep src|grep metric|awk -F" " '{ print $9 }'` echo "$IP $HOSTNAME" >>/etc/hosts #3.install epel.repo# #yum install -y epel-release   cat <<EOF > /etc/yum.repos.d/ceph.repo [ceph] name=ceph baseurl=http://192.168.6.178/ceph/ceph/ gpgcheck=0 priority=1  [ceph-noarch] name=ceph-noarch baseurl=http://192.168.6.178/cephnoarch/ceph-noarch/ gpgcheck=0 priority=1  [ceph-source] name=ceph-source baseurl=http://192.168.6.178/cephsource/ceph-source/ gpgcheck=0 priority=1   EOF       ceph-deploy是用于快速部署集群的工具。 重要：不再维护ceph-deploy。未在Nautilus之前的Ceph版本上进行测试。它不支持RHEL8，CentOS 8或更新的操作系统。      dnf clean all && dnf -y install ceph     说明：本文只介绍ceph这个包，后面会讲解ceph集群部署  

ceph安装完毕
