shell实现部署ftp提供共享yum仓库

脚本实现自动化配置vsftp，并共享opt目录给其它节点机器实现离线源配置

使用脚本需修改以下内容：
ftp_ip为ftp服务器ip
reponame为repo文件名字
dir为仓库目录，默认opt下
houzui为opt目录下的离线仓库，写入到houzui中为数组
使用前还需保持服务器可以下载vsftp服务

脚本实现

#!/bin/bash

ftp_ip="192.168.200.80"
reponame="local.repo"
houzui=("centos" "iaas")
opt="/opt"

if [ "$(hostname -I | awk '{print $1}')" = "$ftp_ip" ]; then
    systemctl stop firewalld
    setenforce 0
    yum install -y vsftpd
    echo "anon_root=$opt" >> /etc/vsftpd/vsftpd.conf
    systemctl enable --now vsftpd
    systemctl restart vsftpd
    rm -rf /etc/yum.repos.d/*
    for repo in "${houzui[@]}"; do
        cat >> "/etc/yum.repos.d/$reponame" <<eof
[$repo]
name=$repo
baseurl=file://$opt/$repo
gpgcheck=0
enabled=1
eof
    done
    yum clean all
    yum repolist
else
    rm -rf /etc/yum.repos.d/*
    for repo in "${houzui[@]}"; do
        cat >> "/etc/yum.repos.d/$reponame" <<eof
[$repo]
name=$repo
baseurl=ftp://$ftp_ip/$repo
gpgcheck=0
enabled=1
eof
    done
    yum clean all
    yum repolist
fi

脚本测试

手动配置好离线仓库

[root@localhost ~]# mkdir /opt/{centos,iaas}
[root@localhost ~]# mount /dev/sr0 /opt/centos/
mount: /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]# cp -rf /opt/centos/* /opt/iaas/

脚本部署

[root@localhost ~]# cat repo.sh
#!/bin/bash

ftp_ip="192.168.200.80"
reponame="local.repo"
houzui=("centos" "iaas")
opt="/opt"

if [ "$(hostname -I | awk '{print $1}')" = "$ftp_ip" ]; then
    systemctl stop firewalld
    setenforce 0
    yum install -y vsftpd
    echo "anon_root=$opt" >> /etc/vsftpd/vsftpd.conf
    systemctl enable --now vsftpd
    systemctl restart vsftpd
    rm -rf /etc/yum.repos.d/*
    for repo in "${houzui[@]}"; do
        cat >> "/etc/yum.repos.d/$reponame" <<eof
[$repo]
name=$repo
baseurl=file://$opt/$repo
gpgcheck=0
enabled=1
eof
    done
    yum clean all
    yum repolist
else
    rm -rf /etc/yum.repos.d/*
    for repo in "${houzui[@]}"; do
        cat >> "/etc/yum.repos.d/$reponame" <<eof
[$repo]
name=$repo
baseurl=ftp://$ftp_ip/$repo
gpgcheck=0
enabled=1
eof
    done
    yum clean all
    yum repolist
fi
