在Centos Stream 8上尝试安装EwoMail 邮件服务器软件，repo源一直出问题

更换操作系统为Centos 7.9，再安装EwoMail 邮件服务器，OK啦

开源免费版不能用POP3和STMP发系统邮件的功能，果断放弃了。

炸，锅，2G内存好像安装不上(已实测2G内存Centos7.9安装上了EwoMail 20220611)

安装根据手册 http://doc.ewomail.com/docs/ewomail/install

安装开始时提示mysql已安装

[root@10-7-188-37 ~]# cd /root/EwoMail/install
[root@10-7-188-37 install]# sh ./start.sh  yourdomian
./start.sh: line 20: [: too many arguments
mysql installed, installation failed
[root@10-7-188-37 install]#

安装中断，于是又卸载了mysql，

安装开始后，前面挺顺利，但是后面又报错有应用安装不上

忘记把代码复制贴过来了

未完待续 2020602

来了，上报错代码

又报错啦

更换yum源为Centos-vault

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
yum clean all && yum makecache

好 ，再试试

cd /root/EwoMail/install
[root@10-7-118-170 install]# cat /etc/centos-release
