搭建Qmail邮件系统（环境篇）

 

                    搭建Qmail的安装环境

 

一     安装以下必须的辅助软件

jpegsrc.v6b.tar.gz
gd-2.0.35.tar.gz
gmp-4.2.1.tar.gz
libtool-1.5.24.tar.gz
libmcrypt-2.5.8.tar.gz
libpng-1.2.18.tar.gz
mhash-0.9.9.tar.gz
openssl-0.9.7e.tar.gz
nginx-0.6.33.tar.gz
pcre-7.3.tar.gz
mrtg-2.15.2.tar.gz

 

安装过程基本上都是：

1）tar zxf

2）进入解压后的目录下./configure

3）make && make install

4）比较特殊的几个如下：

   （（1  pcre     ./configure --enable-utf8 --enable-unicode-properties

   （（2  mrtg    ./configure --prefix=/usr/local/mrtg --with-gd-lib=/usr/local/lib --with-gd-inc=/usr/local/include/

 

 

二  安装apache

 

httpd-2.2.4.tar.gz

安装过程中出现如下错误提示：主要意思是缺少apr和apr-util工具

libtool: install: error: cannot install `libaprutil-1.la' to a directory not ending in /usr/local/http_post/lib
*** Error code 1

Stop in /home/sysadmin/zhangzhn/mailsoft/soft/httpd-2.2.4/srclib/apr-util.
*** Error code 1

Stop in /home/sysadmin/zhangzhn/mailsoft/soft/httpd-2.2.4/srclib.
*** Error code 1

Stop in /home/sysadmin/zhangzhn/mailsoft/soft/httpd-2.2.4.
cp: /usr/local/apache/conf/httpd.conf: No such file or directory
cp: directory /usr/local/apache/htdocs does not exist
cp: directory /usr/local/apache/htdocs does not exist

 

反思一下：编译apache 之前要先编译apr和apr-util，如果系统 自带的话就不用编译，直接编译apache就可以了。但是，为什么一定要编译apache可移植运行库apr和apr-util呢？它们应该只是可选择安装的吧？都有哪些具体的作用呢？还是就是必须装

相关解释：。APR(Apache Portable Runtime)是一个高可移植库，它是Apache HTTP Server 2.x的核心。apr 和apr-util 这两个软件是对后端服务软件进行优化的。因为apache作为前端web服务器软件，如果要整合一些后端的web服务器软件的话，如tomcat ，就要用到这两个软件了。这两个软件系统是自带的，也可以下载源码包安装。都是要编译进apache里面去的，以模块的形式。

 

补救措施：

#whereis apr
#cd  /usr/ports/devel/apr
#make

# cd apr-1.3.8/
#./configure --prefix=/usr/local/apr

# make && make install

#cd ../ apr-util-1.3.9/

#./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config --with-lib=/usr/local/apr/lib
#make && make install

看一下安装情况：

# ls  /usr/local/apr
bin    build-1    include    lib    libdata
# ls  /usr/local/apr-util/
bin    include    lib    libdata

 

apr和apr-util安装成功之后，将之前解压的httpd-2.2.4删掉，重新安装

#tar zxf httpd-2.2.4.tar.gz

#cd httpd-2.2.4

# ./configure --prefix=/usr/local/apache --enable-modules=all --enable-mods-shared==most --with-perl=/usr/bin/perl --enable-cache --enable-rewrite --enable-mime-magic --enable-ssl --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util

# make

# make install                     

在编译的过程中出现了如下状况：主要意思是安装配置文件失败，conf不是一个目录而是一个文件，可能是之前安过的没有清理干净导致的

Installing configuration files
mkdir /usr/local/apache/conf
mkdir: /usr/local/apache/conf: File exists
mkdir /usr/local/apache/conf
mkdir: /usr/local/apache/conf: File exists
mkdir /usr/local/apache/conf/extra
mkdir: /usr/local/apache/conf: No such file or directory
*** Error code 1

Stop in /home/sysadmin/zhangzhn/mailsoft/soft/httpd-2.2.4.
*** Error code 1

Stop in /home/sysadmin/zhangzhn/mailsoft/soft/httpd-2.2.4.

 

# ls -l /usr/local/apache/conf           还真应对了我的上述说法，conf果真以一个文件的形式存在
-rw-r--r--  1 root  wheel  13721 May 19 15:08 /usr/local/apache/conf

那我采取的措施是删掉conf文件再重新make install

# rm -rvf /usr/local/apacheconf

# cd /home/sysadmin/zhangzhn/mailsoft/soft/httpd-2.2.4

# make install

# ls  /usr/local/apache/conf/         这次编译成功了
extra        httpd.conf    magic        mime.types    original

 

 

下面这一步是更新apache配置文件，但是后来做对比以后两个文件没有任何差别，我有点纳闷了，稍后咨询一下前辈吧

# cp /usr/local/apache/conf/httpd.conf /usr/local/apache/conf/httpd.conf.bk
# cp /home/sysadmin/zhangzhn/mailsoft/installserver/httpd.conf /usr/local/apache/conf/

# diff /home/sysadmin/zhangzhn/mailsoft/installserver/httpd.conf  /usr/local/apache/conf/httpd.conf

这一步是必须有的，这是用户访问web的连接 ，

#  cp /home/sysadmin/zhangzhn/mailsoft/installserver/index.php /usr/local/apache/htdocs/

做完这一步之后还有很重要的操作就是将该文件做了如下更改：

将$myip = "122.70.138";  改为  $myip = "119.254.72";

将 Header("Location: http://$myhost/newwebmail/index.php");  中的newwebmail改为webmail

在这做一下解释为什么这么做

122是搬迁机房之前的IP，119是搬迁之后的IP；newwebmail是老版本的连接，webmail新版本的连接

#  cd ..
#  rm -rvf httpd-2.2.4

 

安装http_post的安装编译过程中由于没有指定apr路径，这个整合的apache功能无法进行编译

# ./configure --prefix=/usr/local/http_post -enable-so --enable-modules=all --enable-mods-shared=all

Configuring Apache Portable Runtime library ...

checking for APR... apr-1-config: not found

  setting CC to "gcc"

# ./configure --prefix=/usr/local/http_post -enable-so --enable-modules=all --enable-mods-shared=all --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/

# make

# make install
# cp /usr/local/http_post/conf/httpd.conf /usr/local/http_post/conf/httpd.conf.bak
# cp /home/sysadmin/zhangzhn/mailsoft/installserver/http_post.conf /usr/local/http_post/conf/httpd.conf
# diff /usr/local/http_post/conf/httpd.conf.bak  /usr/local/http_post/conf/httpd.conf  这两个文件是有差别的，在这里不宜透漏

 

 

三  安装c-client

 

c-client.tar

 

tar -xf c-client.tar
cd imap-2006k.DEV.SNAP-0708301750
make bsf
cd c-client

mkdir /usr/local/imap
mkdir /usr/local/imap/include
mkdir /usr/local/imap/lib

cp *.h /usr/local/imap/include/
cp *.h /usr/local/include/
cp c-client.a /usr/local/imap/lib/
cp c-client.a /usr/local/lib/
cp c-client.a /usr/local/imap/lib/libc-client.a
cp c-client.a /usr/local/lib/libc-client.a

cd ../
cd ../
rm -rf imap-2006k.DEV.SNAP-0708301750

 

 

四  安装mysql

 

mysql-5.0.45.tar.gz

 

pw groupadd mysql
pw useradd -n mysql -g mysql
tar zxf mysql-5.0.45.tar.gz
cd mysql-5.0.45
./configure  --prefix=/usr/local/mysql --enable-assembler  --with-mysqld-ldflags=-all-static --with-charset=gbk
make; make install
cp support-files/my-medium.cnf /etc/my.cnf
/usr/local/mysql/bin/mysql_install_db --user=mysql
cd /usr/local/mysql
chown -R mysql var
/usr/local/mysql/bin/mysqld_safe --user=mysql &
rm -rf mysql-5.0.45
/usr/local/mysql/bin/mysql -f -h localhost -u USER -e "use mysql;update user set Password=PASSWORD('PASSWD') where User='USER' and Host='Hostname';"
/usr/local/mysql/bin/mysql -f -h localhost -u USER -e "use mysql; flush privileges;"
紧接着就是给用户授权，这个根据自己的环境需求来做的

 

 

安装完之后，要确认一下授权是否成功

mysql> select Host,User,Password  from user;

 

 

 

五 安装php

 

php-5.2.3.tar.gz       安装选项是根据生产需求而定的，最好不要全盘搬用

./configure --with-openssl /    
        --with-zlib /
        --enable-bcmath /
        --enable-calendar /
        --with-jpeg-dir /
        --with-tiff-dir /
        --with-curl /
        --enable-dba /
        --with-gdbm /
        --with-cdb /
        --with-inifile /
        --enable-ftp /
        --enable-fastcgi /
        --with-flatfile /
        --with-gmp /
        --with-mcrypt /
        --with-mhash /
        --with-pdo-mysql=/usr/local/mysql /
        --with-pdo-sqlite /
        --enable-soap /
        --enable-sqlite-utf8 /
        --with-libxml-dir /
        --with-gd /
        --with-jpeg-dir=/usr/local /
        --with-xpm-dir=/usr/local /
        --with-png-dir=/usr/local /
        --with-zlib-dir=/usr/local /
        --with-freetype /
        --with-ttf=/usr/local /
        --enable-gd-native-ttf /
        --with-gettext=/usr/local /
        --with-iconv=/usr/local /
        --enable-mbstring /
        --with-mysql=/usr/local/mysql /
        --disable-ipv6 /
        --enable-sockets /
        --with-zip /
        --with-imap=/usr/local /
        --enable-memory-limit /
        --enable-zend-multibyte /
        --with-apxs2=/usr/local/apache/bin/apxs

make
make install
#cp php.ini-dist /usr/local/lib/php.ini
cp /home/sysadmin/zhangzhn/mailsoft/installserver/php.ini /usr/local/lib
perl -pi -e 's/register_globals = Off/register_globals = On/g' /usr/local/lib/php.ini
perl -pi -e 's/upload_max_filesize = 2M/upload_max_filesize = 30M/g' /usr/local/lib/php.ini

六 安装Zend

ZendOptimizer-3.0.2-freebsd6.0-i386.tar.gz
ZendOptimizer-3.3.0a-freebsd6.0-i386.tar.gz

 

ln -s /lib/libutil.so.8 /lib/libutil.so.5
ln -s /lib/libm.so.5 /lib/libm.so.4
ln -s /lib/libc.so.7 /lib/libc.so.6
ln -s /lib/libcrypt.so.5 /lib/libcrypt.so.3
tar zxf ZendOptimizer-3.0.2-freebsd6.0-i386.tar.gz
tar zxf ZendOptimizer-3.3.0a-freebsd6.0-i386.tar.gz
cp -p /home/sysadmin/zhangzhn/mailsoft/soft/ZendOptimizer-3.0.2-freebsd6.0-i386/zui_files/dialog /home/sysadmin/zhangzhn/mailsoft/soft/ZendOptimizer-3.3.0a-freebsd6.0-i386/zui_files
/home/sysadmin/zhangzhn/mailsoft/soft/ZendOptimizer-3.3.0a-freebsd6.0-i386/install.sh

最后记得要更新/usr/local/Zend/etc/index.php文件

# diff php.ini php.ini.old  存在以下差异
305c305
< error_reporting  =  E_ALL & ~E_NOTICE & ~E_WARNING        
---
> error_reporting  =  E_ALL & ~E_NOTICE
1276,1278c1276,1279
< zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.0.2
< zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.0.2
< zend_optimizer.version=3.0.2
---
> zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.0
> zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.0
> zend_optimizer.version=3.3.0a
>

 

 

 

 

这次安装下来出了不少问题，看来我得把这些安装过程好好捋一下头绪了，总感觉有点乱

Qmail邮件系统的安装环境已经搭建好了，之后将会继续Qmail安装过程的体验
