RPM安装POSTFIX

RPM安装POSTFIX+DOVECOT2010-10-17 10:50:23标签：linux mail postfix dovecot1。

rpm方式安装好apache+php测试PHP正常访问。

(为webmail先搭建好运行环境)2。

yum安装postfix(安装postfix前先卸载sendmail)和dovecot(pop3+imap),启动两个服务。

3。

配置dovecot: vi /etc/dovecot.conf,dovecot 只需把protocols前的注释去掉,修改protocols = imap imaps pop3 pop3s,并重起 service dovecot restart4。

修改postfix配置文件/etc/postfix/main.cf#myhostname = host.domain.tld ←找到此行，将等号后面的部分改写为主机名myhostname = ←变为此状态，设置系统的主机名#mydomain = domain.tld ←找到此行，将等号后面的部分改写为域名mydomain = ←变为此状态，设置域名（我们将让此处设置将成为E-mail地址“@”后面的部分）#myorigin = $mydomain ←找到此行，将行首的#去掉myorigin = $mydomain ←变为此状态，将发信地址“@”后面的部分设置为域名（非系统主机名）inet_interfaces = localhost ←找到此行，将“localhost”改为“all”inet_interfaces = all ←变为此状态，接受来自所有网络的请求mydestination = $myhostname, localhost.$mydomain, localhost ←找到此行，在行为添加“$mydomain”mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain ←变为此状态，指定发给本地邮件的域名#relay_domains = $mydestination ←找到此行，将行首的#去掉relay_domains = $mydestination ←变为此状态，定义允许转发的域名#mynetworks = 168.100.189.0/28, 127.0.0.0/8 ←找到此行，依照自己的内网情况修改mynetworks = 168.100.189.0/28, 127.0.0.0/8 ←变为此状态，指定内网和本地的IP地址范围#home_mailbox = Maildir/ ←找到这一行，去掉行首的#home_mailbox = Maildir/ ←变为此状态，指定用户邮箱目录 (这个一般不用做)# SHOW SOFTWARE VERSION OR NOT## The smtpd_banner parameter specifies the text that follows the 220# code in the SMTP server's greeting banner. Some people like to see# the mail version advertised. By default, Postfix shows no version.## You MUST specify $myhostname at the start of the text. That is an# RFC requirement. Postfix itself does not care.##smtpd_banner = $myhostname ESMTP $mail_name#smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) ←找到这一行，接此行添加如下行：smtpd_banner = $myhostname ESMTP unknow ←添加这一行，不显示SMTP服务器的相关信息在配置文件的文尾，添加如下行：smtpd_sasl_auth_enable = yes ←服务器使用SMTP认证smtpd_sasl_local_domain = $myhostname ←指定SMTP认证的本地域名（主机名）smtpd_sasl_security_options = noanonymous ←不允许匿名的方式认证smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated,reject_unauth_destinationmessage_size_limit = 15728640 ←规定邮件最大尺寸为15MB vi /usr/lib/sasl2/smtpd.confpwcheck_method: saslauthdlog_level:3mech_list:PLAIN LOGIN如此，postfix应该可以使用本地系统用户收发邮件了。

在RHEL5包管理中添加本地光盘资源

在RHEL5包管理中添加本地光盘资源
--by moroo
安装RHEL5的同学会发现，打开添加删除程序的界面是这个样子的：
这是因为从5开始，使用了yum升级安装机制，安装必须连入网络，你还有red hat的注册账号，或者你就乖乖用命令行方式完成安装。

能不能向以前4一样，采用图形化安装本地光盘中的程序呢，答案是肯定的：挂载光盘，添加路径，清理yum。

3步搞定：
1．挂载光盘到/media/cdrom/中
2-1.在Package Manager中添加一条yum repositories (yum 软件资源库)定义
2-2.我添加了一条RHEL5DVD的定义，关键是Location要指向光盘挂载的位置，使用file://协议。

（这里注意用file:///mountpoint/Server ,因为RPM包在Server目录下！）
2-3.Close时提示出错，没关系选择退出，这会在/etc/yum.repo.d/目录下生成一个rhel5dvd.repo文件:
3.清除yum记录（yum clean all）
重新运行add/remove packages 管理看看！
简单吧^_^。

Redhat5安装图例

Red Hat Enterprise Linux 5 图形模式安装
1. 开机，将安装光盘放入光驱，出现引导画面直接回车安装
2，不用检测光盘，选择“ skip”
3. 进入安装界面，选择“下一步”
4，选择安装过程中（非系统语言）的语言：简体中文
5，选择键盘类型
6，单击下一步，需要安装序列号，此项在您购买的正版CD盒中有一张纸片，数字和字母的组合，将其输入。

如果选择“跳过输入安装号码”
1，您可能不能访问您的订阅包括软件包
2，可能导致没有支持或者未认证的Red Hat Enterprise Linux的安装
3，您将不能获得您的订阅里不包括的软件包的软件和安全性的更新
7，验证安装号成功，提示将格式化硬盘分区
8，对于全新安装的服务器，可以选择删除所有分区
9，弹出警告信息，继续下一步
10，弹出配置网卡ip，此时可以手工输入。

也可以进入系统以后再配置
11，设置好以后下一步，选择时区
12，输入根用户口令
13，根据应用需求选择需要安装的组件
14，选择好以后，下一步继续，注意：这个地方要用鼠标右击每个项目，把所有的可选项包选择进行安装，否则以后安装软件，会提示少库文件或者编译包。

16，单击下一步
17，安装完成,单击重新引导，重启服务器
18，启动过程
19，进入登陆前的系统信息设置界面
20，输入用户名密码
21，登陆成功
至此PER805 服务器Redhat Enterprise linux 5.0安装完成。

自已redhat5安装oracle的整个过程

自已redhat5安装oracle的整个过程一．安装jdk1.我使用的是jdk-1.6.0_23-linux-i586.rpm.bin下载后的BIN文件可以直接执行2.使用root用户，执行以下几步# chmod 755 jdk-1.6.0_23-linux-i586.rpm.bin# ./ jdk-1.6.0_23-linux-i586.rpm.bin此步完成后，会生成jdk-1.6.0_23-linux-i586.rpm的文件默认安装到了/usr/java/jdk1.6.0_233.设置环境变量vi /etc/profile在文件中增加如下内容：JAVA_HOME=/usr/java/jdk1.6.0_23JRE_HOME=/usr/java/jdk1.6.0_23/jrePATH=$PATH:$JAVA_HOME/bin:JRE_HOME/binCLASSPATH=.:$JAVA_HOME/lib/jt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/libexport JAVA_HOME JRE_HOME PATH CLASSPATH按Esc,然后:wq保存退出4.使环境变量生效Source /etc/profile此时可以查看jdk的环境配置echo $JAVA_HOME(会显示JDK所在目录)二．安装oracle1.检查安装包(当前用户是root)rpm -q gcc make binutils openmotif setarch compat-db compat-gcccompat-gcc-c++compat-libstdc++ compat-libstdc++-devel libXp使用此命令可以查看这些rpm包是否安装，由于缺失的包之间有严格的依赖关系，所以必须按照如下顺序安装缺失的包:rpm -Uvh compat-db-4*rpm -Uvh libaio-0*rpm -Uvh compat-libstdc++-33-3*rpm -Uvh glibc-headers-2.5-12.i386.rpmrpm -Uvh glibc-devel-2.5-12.i386.rpmrpm -Uvh compat-gcc-34-3*rpm -Uvh compat-gcc-34-c++-3*rpm -Uvh libXp-1*rpm -Uvh openmotif-2*rpm -Uvh gcc-4*rpm -Uvh glibc-2.5-12.i686.rpmrpm -Uvh libgomp-4.1.1-52.el5.i386.rpmrpm -Uvh gcc-4.1.1-52.el5.i386.rpm其中U是升级的意思update。

快速搭建基于postfix+dovecot的邮件系统

安装环境：Centos5.5 32位系统rpm安装apache、mysql、php编译安装postfix、dovecot一、安装Centos5.5系统将Centos5.5光盘放入光驱启动系统出现如下画面直接回车系统提示”是否需要校验cd媒介”,选择“Skip”跳过安装欢迎界面：点击next选择安装界面语言选择键盘类型默认即可分区设置选择“是”点击“下一步”选择“检验和修改分区方案”选择“是”然后点击“下一步”手动分区（如果不想手动分区在上一步不要选择“检验和修改分区方案”）点击“重置”创建boot分区大小分300M（默认的100M也足够了）创建交换分区（如果物理内存较小swap分区大小就设为物理内存两倍，如果物理内存较大设为同内存一样大就Ok了）创建home分区（主要用于存放数据）创建根分区（）完成分区安装grub引导程序设置网络设置时区设置超级用户root密码软件选择界面选择“现在定制”如果不需要图形界面可以将Desktop-Gnome去掉“应用程序”中只选择“编辑器”就行了“服务器”中选择“MySQL数据库”、“万维网服务器”（也就是mysql和apache）选择“MySQL数据库”---可选的软件包选择php-mysql组件“开发”中选择开发工具开始安装系统和定制的软件安装完成系统设置向导禁用防火墙禁用SElinux不用选择Kdump直接点击“前进”即可时间和日期设置创建用户（创建普通用户，如果不想创建直接点击“前进”）重启系统完成设置打开终端修改/etc/inittab 将id:5:initdefault:改为id:3:initdefault:设置为3用户模式启动系统（不带图形界面）如果之前安装的时候没有安装Desktop-Gnom这里默认进入3用户模式就不需要设置该项如果在装系统时没有安装apache、mysql、php系统安装完成之后可以通过rpm或者yum在线安装apache、mysql、php#yum install httpd-manual httpd system-config-httpd#yum install php-mysql mysql libdbi-dbd-mysql mysql-connector-odbc mysql-server mysql-devel #yum install php-cli php-mysql php-ldap php-pdo php php-common开启apache、mysql#service httpd start#service mysqld start测试phpvi /var/www/html/test.php内容如下:<?phpphpinfo();?>在浏览器里输入http://your ip/test.php成功运行将会出现PHP的logo图标和配置信息。

在RHEL5.0中用YUM解决RPM包的依赖关系

一、使用yum实现本地安装RPM包的依赖关系：1．添加一块硬盘，新分区并挂载到/install目录(也可以是其他目录)或直接在现有文件树中建一个新目录如/install2．将linux的光盘放入光驱并挂载光驱，将光盘中的所有内容复制到/install目录中：#cd 光驱挂载点#cp –a * /install3．删除子目录中的repodata目录：（LINUX5.0的RPM包存在于Cluster,ClusterStorage,Server,VT目录中。

）4．安装createrepo软件包,该RPM包在Server目录中。

5．使用createrepo /install创建RPM包的依赖关系库。

6．编辑索引文件，索引文件的路径：/etc/yum.repos.d/[root@localhost yum.repos.d]# vi /etc/yum.repos.d/server.repo (重命名后的文件名,也可以不重名)[server] --仓库的名字最好和索引文件名一致name=server --任意指定#baseurl=ftp:///pub/redhat/linux/enterprise/$releasever/en/os/$basearch/Debuginfo/--注释掉原URLbaseurl=file:///install --指定本地路径enabled=1 --使该仓库生效gpgcheck=0 --取消gpg校验#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release7．验证：例如安装gcc：#yum install gcc*二、使用YUM实现网络安装RPM包的依赖关系：1．服务器端设置：先按使用YUM本地安装RPM包的依赖关系设置关系库，然后安装VSFTPD（也可以是APACHE），并设置匿名FTP的工作目录为/install目录（方法是修改VSFTPD.CONF文件添加anon_root=/install 或修改ftp系统用户的宿主目录为/install）.启动VSFTPD服务。
