CentOS下Extmail的搭建

关于Error: xz compression not available2015-05-30 23:562067人阅读评论(0)举报找到原因是安装软件时错误安装了CENTOS 7版本的软件导致yum不可用。

附上原文：Your "fix" removes the repository entirely. The correct fix is to remove the cached files for epel under /var/cache/yum/epel and to uninstall the EPEL *7* version of the rpm which is designed to install on CentOS/RHEL7 not on CentOS 6.解决方法：1.gedit /root/install.log域名及主机名--------------------------------------Domain：Hostname：--------------------------------------数据库信息--------------------------------------Mysql（postfixadmin）DBNAME ===> postfixadminuser ===> postfixpassword ===> postfixadmin--------------------------------------一、环境部署预备1、域名及主机名设置略……2、配置新yum 源（网易）[root@mail ~]# yum -y install wget[root@mail ~]# cd /etc/yum.repos.d/[root@mail yum.repos.d]# mkdir backup[root@mail yum.repos.d]# mv CentOS-* backup/[root@mail yum.repos.d]# wget /.help/CentOS6-Base-163.repo//此步骤可选，目的为今后yum安装amavisd-new、clamav 等[root@mail ~]# rpm -ivh /pub/epel/6/i386/epel-release-6-8.noarch.rpm//清空yum缓存及更新系统[root@mail ~]# yum clean all; yum update -y3、LAMP 环境[root@mail ~]# yum -y install httpd mysql mysql-devel mysql-server php php-pecl-Fileinfo php-mcrypt php-devel php-mysql php-common php-mbstring php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc pcre pcre-devel//配置apache，并让apache支持php[root@mail ~]# vi /etc/httpd/conf/httpd.confAddType application/x-httpd-php .php #添加对php程序的支持PHPIniDir "/etc/php.ini" #指定php.ini配置文件路径DirectoryIndex index.php index.html #指定首页文件类型#取消ServerName前的注释，否则启动httpd 时提示276行4、配置mysql，为postfixadmin 准备好数据库及认证用户[root@mail ~]#service mysqld start \q可断开连接[root@mail ~]#chkconfig mysqld on[root@mail ~]# mysql -uroot -pmysql> create database postfix character set utf8;mysql> grant all privileges on postfix.* to postfix@localhost identified by 'postfixadmin'; mysql> flush privileges;mysql> exit5、添加邮件虚拟用户vmail[root@mail ~]# useradd -u 2000 -d /var/vmail -c "Virtual Mail user" -s/sbin/nologin vmail二、配置postfix[root@mail ~]# vi /etc/postfix/main.cf################# Main configure ####################hostname = mydomain = myorigin = $mydomaininet_interfaces = all#注意这里，不能设置成与hostname与mydomain一致，不然收不到邮件mydestination = localhostmynetworks = 127.0.0.0/8#不对client进行反向域名解析disable_dns_lookups = yes#允许对一个目标域名发送的邮件并发数为20个default_destination_concurrency_limit = 20#邮件的并发进程限制（根据服务器的性能定义）default_process_limit = 50#只监听ipv4net_interfaces = ipv4################## Virtual mail configure #######################virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_alias_maps = proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cfvirtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql_virtual_mailbox_maps.cfvirtual_mailbox_base = /var/vmail#注意uid 与gid 与之前的建立的vmail账号是一致的，可以用# id vmail查询virtual_uid_maps = static:2000virtual_gid_maps = static:2000virtual_transport = dovecotdovecot_destination_recipient_limit = 1proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains$relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps################ SASL SUPPORT FOR CLIENTS ####################### smtpd_sasl_auth_enable = yessmtpd_sasl_type = dovecotsmtpd_sasl_security_options = noanonymous#以下的两个选项可以任选一个，不过必须要与dovecot 一致#smtpd_sasl_path = /var/run/dovecot/auth-clientsmtpd_sasl_path = private/authbroken_sasl_auth_clients = yessmtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,reject_unauth_destination################## Mail Quota configure ########################mail transport max size:20Mmessage_size_limit = 20480000# 虚拟邮件用户使用的最大容量，需在postfixadmin 中启用quota（$CONF['used_quotas'] = 'YES';）才生效。

参数不能与myorigin相同；•virtual_tranport = dovecot ，网上有些教程是virtual；•vmail 的GID与UID 为2000•/var/vmail 权限问题，日志里会提示Q：传输附件失败A：没有定义最大邮件传递大小，postfix 默认的传递大小查询：[root@mail ~]# postconf | grep message_size_limitmessage_size_limit = 10240000#默认为10M#编辑main.cf 定义合适邮件传输的大小#查询数据库中的数据[root@mail ~]# postmap -q mysql:/etc/postfix/mysql_virtual_domains_maps.cf[root@mail ~]# postmap -q

[垃圾邮件]等），客户端默认使用IMAP协议来接收邮件时，只存在一个收件箱及草稿箱，其它的目录需要手动建立（暂时没有好的思路），写了个简单得不能再简单的SHELL脚本。
