postfix源码包升级

                                                postfix源码包升级

将本机的postfix-2.6.6升级到postfix-2.8.5

#rpm -q postfix //查看当前版本

#postconf -m //查看支持的对象

#postconf -a

#postconf -A //发现postfix支持cyrus dovecot

升级时，我们需要重新编译源码包，并加入相关对mysql cyrus的支持

#tar zxf postfix-2.8.5.tar.gz

#cd postfix-2.8.5

#cd README_FILES/

查看说明文档

#less MYSQL_README /make 查找make字符串

make -f Makefile.init makefiles \

'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include' \

'AUXLIBS=-L/usr/local/mysql/lib -lmysqlclient -lz -lm'

由于安装mysql时的二进制包，函数库路径不同，故需查看自己的主机环境

#rpm -ql mysql-devel //若没安装请自行安装

/usr/include/mysql

/usr/lib64/mysql/xxxxxx

编译时，需对相关路径进行修改

#make -f Makefile.init makefiles \

'CCARGS=-DHAS_MYSQL -I/usr/include/mysql' \

'AUXLIBS=-L/usr/lib64/mysql -lmysqlclient -lz -lm'

此时只加入了对mysql的支持，如要加入cyrus-sasl tls的支持，需加入相关参数

#less SASL_README

Cyrus SASL version 2.1.x

% make tidy # if you have left-over files from a previous build

% make makefiles CCARGS="-DUSE_SASL_AUTH -DUSE_CYRUS_SASL \

-I/usr/local/include/sasl" AUXLIBS="-L/usr/local/lib -lsasl2"

Cyrus SASL version 1.5.x

% make tidy # if you have left-over files from a previous build

% make makefiles CCARGS="-DUSE_SASL_AUTH -DUSE_CYRUS_SASL \

-I/usr/local/include" AUXLIBS="-L/usr/local/lib -lsasl"

以上说明了对于不同cyrus sasl版本的不同编译方法，编译前需先查看

#rpm -ql cyrus-sasl-devel //若没安装请安装

同理

#less TLS_README

* If the OpenSSL include files (such as ssl.h) are in directory /usr/include/

openssl, and the OpenSSL libraries (such as libssl.so and libcrypto.so) are in directory /usr/lib:

% make tidy # if you have left-over files from a previous build

% make makefiles CCARGS="-DUSE_TLS" AUXLIBS="-lssl -lcrypto"

* If the OpenSSL include files (such as ssl.h) are in directory /usr/local/

include/openssl, and the OpenSSL libraries (such as libssl.so and

libcrypto.so) are in directory /usr/local/lib:

% make tidy # if you have left-over files from a previous build

% make makefiles CCARGS="-DUSE_TLS -I/usr/local/include" \

AUXLIBS="-L/usr/local/lib -lssl -lcrypto"

以上说明，针对不同的openssl安装路径的不同，有不同的安装方式

#rpm -ql openssl-devel

#make tidy 或 make clean //清除刚才的编译文件，以便重新编译；也可删除该目录，再重新解压缩，再编译

本机最后完整编译方式为

#make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS' 'AUXLIBS=-L/usr/lib64/mysql -lmysqlclient -lz -lm -L/usr/lib64/ -lsasl2 -lssl -lcrypto '

注意：编译路径须在postfix-2.8.5这个解压缩目录类

编译过程中可能需要一些其他软件包，如db*-devel

#yum install db*-devel

#make upgrade //升级

#postconf -m //发现少了对ldap的支持

#postconf -a

#postconf -A
