CentOS5.1上安装基于postfix的全功能邮件服务器

CentOS5.1上安装基于postfix的全功能邮件服务器 

一：试验环境介绍 软件：vmware workstation6.02 vm：创建一个redhat as5 vm，8g硬盘，删除软驱和声卡 主机名（hostname）:centos ip：192.168.1.168 dns：192.168.1.1（配置完后，需要修改，指向192.168.1.168，修改/etc/resolv.conf), 邮件服务器的名字为mail.test.com dns server:ns1.test.com dns ip:192.168.1.168 ip：192.168.1.168 www.test.com 192.168.1.168 mail.test.com 192.168.1.168 系统采用centos5.1，采用最小化安装，所有的选项采用系统默认。 二：安装软件前准备 1：关闭无用的服务和selinux，需要重新启动才能生效 2：配置ssh，允许root登陆 3：配置yum，快速更新 4：把所有的软件上传到/usr/src目录下 5：通过yum安装gcc， gcc-c++ 6：卸载sendmail (yum y remove sendmail) 7：重新启动机器，给系统做快照，后面每完成一项工作都给系统做一个快照  三：安装bind 安装bind tar zxvf bind-9.4.2.tar.gz cd bind-9.4.2 ./configure --prefix=/usr/local/named && make && make install groupadd bind useradd -g bind -d /usr/local/named -s /sbin/nologin bind cd /usr/local/named/etc /usr/local/named/sbin/rndc-confgen > rndc.conf cat rndc.conf > rndc.key chmod 777 /usr/local/named/var tail -10 rndc.conf | head -9 | sed s/#\ //g > named.conf 配置 1：编辑/usr/local/named/etc 目录下的named.conf 文件 vi named.conf 添加下面内容( ################# options { directory "/usr/local/named/var"; //域名文件存放的绝对路径 pid-file "named.pid"; //如果bind启动，自动会在/usr/local/named/var目录生成一个named.pid文件，打开文件就是named进程的ID }; zone "."

/usr/local/named/sbin/named -c /usr/local/named/etc/named.conf -u bind &   四：安装ncurses-5.6 这个软件如果不安装，安装mysql的时候会报错，我把解压，编译，安装一行代码来安装。 tar zxvf ncurses-5.6.tar.gz && cd ncurses-5.6 && ./configure --prefix=/usr --with-shared --without-debug && make && make install && cd ..   五：安装mysql tar -zxvf mysql-5.0.51a.tar.gz && cd mysql-5.0.51a && ./configure --with-mysqld-user=mysql --prefix=/usr/local/mysql5 --with-charset=gbk --with-extra-charset=all --without-isam --exec-prefix=/usr/local/mysql5 && make && make install groupadd mysql useradd -g mysql mysql /usr/src/mysql-5.0.51a/scripts/mysql_install_db cp /usr/local/mysql5/share/mysql/my-medium.cnf /usr/local/mysql5/var/my.cnf cp /usr/local/mysql5/share/mysql/mysql.server /etc/init.d/mysqld chkconfig --add mysqld chkconfig --level 2345 mysqld on chown mysql:mysql -R /usr/local/mysql5/ service mysqld start ln -s /usr/local/mysql5/bin/mysql /sbin/mysql ln -s /usr/local/mysql5/bin/mysqladmin /sbin/mysqladmin 配置库文件搜索路径 echo "/usr/local/mysql5/lib/mysql" >> /etc/ld.so.conf ldconfig -v 添加/usr/local/mysql/bin到环境变量PATH中 export PATH=$PATH:/usr/local/mysql5/bin 测试 netstat -nplt | grep mysql ps aux|grep mysql 六：安装ZLIB2   如果不安装，等下编译安装openssl 就会报错，所以提前编译安装  tar zxvf zlib-1.2.3.tar.gz && cd zlib-1.2.3 && ./configure && make && make install && cd .. 七：安装openssl tar zxvf openssl-0.9.8g.tar.gz && cd openssl-0.9.8g && ./config shared zlib && make && make test && make install mv /usr/bin/openssl /usr/bin/openssl.OFF mv /usr/include/openssl /usr/include/openssl.OFF rm /usr/lib/libssl.so ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl ln -s /usr/local/ssl/include/openssl /usr/include/openssl ln -sv /usr/local/ssl/lib/libssl.so.0.9.8 /usr/lib/libssl.so 配置库文件搜索路径 echo "/usr/local/ssl/lib" >> /etc/ld.so.conf ldconfig -v 检测安装结果 openssl version 八：安装安装sasl-2.1.22 tar zxvf cyrus-sasl-2.1.22.tar.gz && cd cyrus-sasl-2.1.22 && ./configure --prefix=/usr/local/sasl2 --disable-gssapi --disable-anon --disable-sample --disable-digest --enable-plain --enable-login --enable-sql --with-mysql=/usr/local/mysql5 -with-mysql-includes=/usr/local/mysql5/include/mysql --with-mysql-libs=/usr/local/mysql5/lib/mysql --with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket && cp mac/libdes/public/des.h ./ && make && make install 关闭原有的sasl，并创建链接（这个地方我和原文有不同）postfix 2.3以后的版本会分别在/usr/local/lib和/usr/local/include中搜索sasl库文件及头文件，故还须将其链接至此目录中： mv /usr/lib/sasl2 /usr/lib/sasl2.save mv /usr/lib/libsasl2.so.2 /usr/lib/libsasl2.so.2.save mv /usr/lib/libsasl2.so.2.0.22 /usr/lib/libsasl2.so.2.0.22.save ln -sv /usr/local/sasl2/lib/* /usr/lib ln -sv /usr/local/sasl2/lib/* /usr/local/lib ln -sv /usr/local/sasl2/include/sasl/* /usr/local/include   创建运行时需要的目录并调试启动 mkdir -pv /var/state/saslauthd /usr/local/sasl2/sbin/saslauthd -a shadow pam -d 启动并测试 /usr/local/sasl2/sbin/saslauthd -a shadow pam 配置库文件搜索路径 echo "/usr/local/sasl2/lib" >> /etc/ld.so.conf echo "/usr/local/sasl2/lib/sasl2" >> /etc/ld.so.conf ldconfig -v 开机自动启动 echo "/usr/local/sasl2/sbin/saslauthd -a shadow pam">>/etc/rc.local  九：安装BerkeleyDB tar zxvf db-4.5.20.tar.gz cd db-4.5.20/build_unix ../dist/configure --prefix=/usr/local/BerkeleyDB make && make install ln -sv /usr/local/BerkeleyDB/include /usr/include/db4 ln -sv /usr/local/BerkeleyDB/include/db.h /usr/include/db.h ln -sv /usr/local/BerkeleyDB/include/db_cxx.h /usr/include/db_cxx.h echo "/usr/local/BerkeleyDB/lib" >> /etc/ld.so.conf ldconfig 十：安装httpd-2.2.8  tar zxvf httpd-2.2.8.tar.gz cd httpd-2.2.8 ./configure --prefix=/usr/local/apache2 --enable-so --enable-ssl --with-ssl=/usr/local/ssl --enable-track-vars --enable-rewrite --with-zlib --enable-mods-shared=most --enable-suexec --with-suexec-caller=daemon && make && make install 编辑httpd.conf vi /usr/local/apache2/conf/httpd.conf DirectoryIndex index.html 改为 DirectoryIndex index.html index.htm default.htm default.html index.php index.php3 index.jsp #ServerName www.example.com:80 改为 ServerName www.example.com:80 加上下面两行 AddType application/x-httpd-php .php .phtml AddType application/x-httpd-php-source .phps apache 开机启动 ln -s /usr/local/apache2/bin/apachectl /etc/init.d/httpd vi /etc/init.d/httpd 在第三行添加以下内容 #chkconfig:345 85 15 #description: Start and stops the Apache HTTP Server. chmod +x /etc/rc.d/init.d/httpd chkconfig --add httpd 十一：安装GD 1：安装PNG ##########libpng########### tar zxvf libpng-1.2.26.tar.gz && cd libpng-1.2.26 && cp scripts/makefile.linux ./makefile && ./configure --prefix=/usr/local/libpng && make && make install 2：安装freetype ##########freetype######### tar zxvf freetype-2.3.5.tar.gz && cd freetype-2.3.5 && ./configure && make && make install 3：安装JPEG6 #########jpeg############### tar zxvf jpegsrc.v6b.tar.gz && cd jpeg-6b && mkdir -pv /usr/local/jpeg/{,bin,lib,include,man/man1,man1} && ./configure --prefix=/usr/local/jpeg --enable-shared --enable- static && make && make install 4：安装GD ########GD########### tar zxvf gd-2.0.35.tar.gz && cd gd-2.0.35 && ./configure --with-png --with-freetype --with-jpeg=/usr/local/jpeg/ make && make install 十二：安装php  安装LIBXML2 #####libxml2 ##### tar zxvf libxml2-2.6.31.tar.gz && cd libxml2-2.6.31 && ./configure --prefix=/usr/local/libxml2 && make && make install && cp xml2-config /usr/bin && cd .. 安装libmcrypt-2.5.7.tar.gz #####libmcrypt-2.5.7 ##### tar zxvf libmcrypt-2.5.7.tar.gz && cd libmcrypt-2.5.7 && ./configure && make && make install && cd .. 安装PHP5.2.5 #########php-5.2.5########## tar zxvf php-5.2.5.tar.gz && cd php-5.2.5 && ./configure --prefix=/usr/local/php5 --with-mysql=/usr/local/mysql5 --with-apxs2=/usr/local/apache2/bin/apxs --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/local/include/freetype2 --with-zlib --with-png-dir=usr/local/libpng12 --with-libxml-dir=/usr/local/libxml2 --with-gd --enable-ftp --enable-sockets -enable-mbstring=all- --with-mcrypt --with-mysqli=/usr/local/mysql5/bin/mysql_config && make && make install && cp php.ini-dist /usr/local/php5/lib/php.ini && cd ..  十三：安装Postfix-2.4.5 groupadd -g 2525 postfix useradd -g postfix -u 2525 -s /sbin/nologin -M postfix groupadd -g 2526 postdrop useradd -g postdrop -u 2526 -s /bin/false -M postdrop tar zxvf postfix-2.4.5.tar.gz && cd postfix-2.4.5 && make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql5/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/sasl2/include/sasl -I/usr/local/BerkeleyDB/include -DUSE_TLS -I/usr/local/ssl/include/openssl ' 'AUXLIBS=-L/usr/local/mysql5/lib/mysql -lmysqlclient -lz -lm -L/usr/local/sasl2/lib -lsasl2 -L/usr/local/BerkeleyDB/lib -L/usr/local/ssl/lib -lssl -lcrypto'&& make && make install 按照以下的提示输入相关的路径([]号中的是缺省值，”]”后的是输入值) 　　install_root: [/] / 　　tempdir: [/usr/local/src/ postfix-2.4.5] /tmp 　　config_directory: [/etc/postfix] /etc/postfix 　　daemon_directory: [/usr/libexec/postfix] /usr/local/postfix/libexec 　　command_directory: [/usr/sbin] /usr/local/postfix/sbin 　　queue_directory: [/var/spool/postfix] 　　sendmail_path: [/usr/sbin/sendmail] 　　newaliases_path: [/usr/bin/newaliases] 　　mailq_path: [/usr/bin/mailq] 　　mail_owner: [postfix] 　　setgid_group: [postdrop] html_directory: [no] /usr/local/apache2/htdocs/mail/postfix_html manpages: [/usr/local/man] /usr/local/postfix/man readme_directory: [no] 生成别名二进制文件，这个步骤如果忽略，会造成postfix效率极低： # newaliases 生成的aliases.db默认是在/etc/目录下，须做软连接，后面的lias_maps配置会用到 ln -s /etc/aliases.db /etc/postfix/aliases.db 2．进行一些基本配置，测试启动postfix并进行发信 #vi /etc/postfix/main.cf 修改以下几项为您需要的配置 myhostname = mail.benet.org myorigin = benet.org mydomain = benet.org mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mynetworks = 192.168.1.0/24, 127.0.0.0/8 说明: myorigin参数用来指明发件人所在的域名； mydestination参数指定postfix接收邮件时收件人的域名，即您的postfix系统要接收到哪个域名的邮件； myhostname 参数指定运行postfix邮件系统的主机的主机名，默认情况下，其值被设定为本地机器名； mydomain参数指定您的域名，默认情况下，postfix将myhostname的第一部分删除而作为mydomain的值； mynetworks 参数指定你所在的网络的网络地址，postfix系统根据其值来区别用户是远程的还是本地的，如果是本地网络用户则允许其访问； inet_interfaces 参数指定postfix系统监听的网络接口； 注意： 1、在postfix的配置文件中，参数行和注释行是不能处在同一行中的； 2、任何一个参数的值都不需要加引号，否则，引号将会被当作参数值的一部分来使用； 3、每修改参数及其值后执行 postfix reload 即可令其生效；但若修改了inet_interfaces，则需重新启动postfix； 4、如果一个参数的值有多个，可以将它们放在不同的行中，只需要在其后的每个行前多置一个空格即可；postfix会把第一个字符为空格或tab的文本行视为上一行的延续； 启动postfix /usr/local/postfix/sbin/postfix start 添加自启动 echo "/mail/postfix2.4.7/sbin/postfix start" >> /etc/rc.local   测试postfix [root@centos mail]# telnet mail.test.com 25 Trying 192.168.1.168... Connected to mail.test.com (192.168.1.168). Escape character is '^]'. 220 mail.test.com ESMTP Postfix ehlo mail.test.com 250-mail.test.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from:[email protected] 250 2.1.0 Ok RCPT TO:[email protected] 250 2.1.5 Ok data 354 End data with <CR><LF>.<CR><LF> subject:Mail test!

make # make install  备注：。 如果出现以下错误 configure: error: --with-authmysql specified but no mysqlclient.so 须增加以下链接，重新编译 # ln -s /usr/local/mysql/bin/mysql_config /usr/bin/mysql_config 这是因为无法找到mysql，我的处理方面是输入mysql的路径，估计这个地方有点问题。 chmod 755 /usr/local/courier-authlib/var/spool/authdaemon cp /etc/authdaemonrc.dist /etc/authdaemonrc cp /etc/authmysqlrc.dist /etc/authmysqlrc 修改/etc/authdaemonrc 文件 authmodulelist="authmysql" authmodulelistorig="authmysql" daemons=10 编辑/etc/authmysqlrc 为以下内容，其中2525，2525 为postfix 用户的UID和GID。 MYSQL_SERVER localhost MYSQL_PORT 3306 (指定你的mysql监听的端口，这里使用默认的3306) MYSQL_USERNAME extmail (这时为后文要用的数据库的所有者的用户名) MYSQL_PASSWORD extmail (密码) MYSQL_SOCKET /tmp/mysql.sock MYSQL_DATABASE extmail MYSQL_USER_TABLE mailbox MYSQL_CRYPT_PWFIELD password MYSQL_UID_FIELD '2525' MYSQL_GID_FIELD '2525' MYSQL_LOGIN_FIELD username MYSQL_HOME_FIELD concat('/var/mailbox/',maildir) MYSQL_NAME_FIELD name MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir) 编辑/etc/authmysqlrc 为以下内容，其中2525，2525 为postfix 用户的UID和GID。 MYSQL_USER_TABLE mailbox MYSQL_CRYPT_PWFIELD password MYSQL_UID_FIELD '2525' MYSQL_GID_FIELD '2525' MYSQL_LOGIN_FIELD username MYSQL_HOME_FIELD concat('/var/mailbox/',maildir) MYSQL_NAME_FIELD name MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir) cp /usr/src/courier-authlib-0.59.3/courier-authlib.sysvinit /etc/init.d/courier-authlib chmod 755 /etc/init.d/courier-authlib chkconfig --add courier-authlib chkconfig --level 2345 courier-authlib on echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf ldconfig -v service courier-authlib start (启动服务) 十七：安装Courier-IMAP tar jxvf courier-imap-4.1.3.tar.bz2 cd courier-imap-4.1.3 ./configure --prefix=/usr/local/courier-imap --with-redhat --enable-unicode --disable-root-check --with-trashquota --without-ipv6 CPPFLAGS='-I/usr/local/ssl/include/openssl -I/usr/local/courier-authlib/include' LDFLAGS='-L/usr/local/courier-authlib/lib/courier-authlib' COURIERAUTHCONFIG='/usr/local/courier-authlib/bin/courierauthconfig' # make # make install cp /usr/local/courier-imap/etc/imapd.dist /usr/local/courier-imap/etc/imapd cp /usr/local/courier-imap/etc/imapd-ssl.dist /usr/local/courier-imap/etc/imapd-ssl cp /usr/local/courier-imap/etc/pop3d.dist /usr/local/courier-imap/etc/pop3d cp /usr/local/courier-imap/etc/pop3d-ssl.dist /usr/local/courier-imap/etc/pop3d-ssl 配置Courier-IMAP，为用户提供pop3服务： vi /usr/local/courier-imap/etc/pop3d POP3DSTART=YES 注：如果你想为用户提供IMAP服务，则需在"/usr/local/courier-imap/etc/imapd"文件中设置"IMAPDSTART=yes"；其它类同； 新建虚拟用户邮箱所在的目录，并将其权限赋予postfix用户： mkdir –pv /var/mailbox chown -R postfix /var/mailbox cp /usr/src/courier-imap-4.1.3/courier-imap.sysvinit /etc/rc.d/init.d/courier-imapd chmod 755 /etc/rc.d/init.d/courier-imapd chkconfig --add courier-imapd chkconfig --level 2345 courier-imapd on service courier-imapd start 接下来重新配置SMTP 认证，编辑 /usr/local/lib/sasl2/smtpd.conf ，确保其为以下内容： pwcheck_method: authdaemond log_level: 3 mech_list:PLAIN LOGIN authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket 十八：安装Extmail-1.0.2 1、安装 tar zxvf extmail-1.0.2.tar.gz mkdir -pv /usr/local/apache2/htdocs/extsuite mv extmail-1.0.3 /usr/local/apache2/htdocs/extsuite/extmail cp /usr/local/apache2/htdocs/extsuite/extmail/webmail.cf.default /usr/local/apache2/htdocs/extsuite/extmail/webmail.cf 2、修改主配置文件 #vi /var/www/extsuite/extmail/webmail.cf 部分修改选项的说明： SYS_MESSAGE_SIZE_LIMIT = 5242880 用户可以发送的最大邮件 SYS_USER_LANG = en_US 语言选项，可改作： SYS_USER_LANG = zh_CN SYS_MAILDIR_BASE = /home/domains 此处即为您在前文所设置的用户邮件的存放目录，可改作： SYS_MAILDIR_BASE = /var/mailbox SYS_MYSQL_USER = db_user SYS_MYSQL_PASS = db_pass 以上两句句用来设置连接数据库服务器所使用用户名、密码和邮件服务器用到的数据库，这里修改为： SYS_MYSQL_USER = postfix SYS_MYSQL_PASS = 123456 SYS_MYSQL_HOST = localhost 指明数据库服务器主机名，这里默认即可 SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock 连接数据库的sock文件位置，这里修改为： SYS_MYSQL_SOCKET = /tmp/mysql.sock SYS_MYSQL_TABLE = mailbox SYS_MYSQL_ATTR_USERNAME = username SYS_MYSQL_ATTR_DOMAIN = domain SYS_MYSQL_ATTR_PASSWD = password 以上用来指定验正用户登录里所用到的表，以及用户名、域名和用户密码分别对应的表中列的名称；这里默认即可 SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket 此句用来指明authdaemo socket文件的位置，这里修改为： SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket 3、apache相关配置 vi /usr/local/apache2/conf/httpd.conf User daemon Group daemon 改为 User postfix Group postfix vi /usr/local/apache2/conf/extra/httpd-vhosts.conf 将原有的虚拟机配置示例去除，加入 <VirtualHost *:80> ServerName mail.test.com DocumentRoot /usr/local/apache2/htdocs/extsuite/extmail/html ErrorLog logs/mail.test.com-error_log CustomLog logs/mail.test.com-access_log common ScriptAlias /extmail/cgi /usr/local/apache2/htdocs/extsuite/extmail/cgi Alias /extmail /usr/local/apache2/htdocs/extsuite/extmail/html </VirtualHost> 修改 cgi执行文件属主为apache运行身份用户：  chown -R postfix.postfix /usr/local/apache2/htdocs/extsuite/extmail/cgi/  4、依赖关系的解决 extmail将会用到perl的DBD::Mysql和Unix::syslogd功能 tar -zxvf Unix-Syslog-1.0.tar.gz cd Unix-Syslog-1.0 perl Makefile.PL make make install 如果直接安装DBD-mysql，会出现Can't locate DBI/DBD.pm in @INC的错误，所以你需要安装 perl-DBI yum -y install perl-DBI tar -zxvf DBD-mysql-4.006.tar.gz cd DBD-mysql-4.006 perl Makefile.PL (此步骤中如果出现类同Can't exec "mysql_config": No such file or directory at Makefile.PL line 76. 的错误是因为您的mysql的bin目录没有输出至$PATH环境变量) make make install 如果在后面访问extman的时候出现以下错误日志 error: /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/DBD/ mysql/mysql.so: undefined symbol: DBIc_TRACE_LEVEL 那是DBD-mysql的版本问题造成的，请装其他版本的DBD-mysql，比如DBD-mysql-3.0008  十九：安装Extman-0.2.3  1、安装及基本配置 Extman的管理员登陆校验码需要perl-GD模块，而perl-GD需要gd，(gd已经安装） 安装perl-GD： tar -zxvf GD-2.35.tar.gz cd GD-2.35 perl Makefile.PL make make install 安装Extman： tar -zxvf extman-0.2.3.tar.gz mv extman-0.2.3 /usr/local/apache2/htdo
