Postfix邮件服务器安装

一、安装mysql-5.0.45#groupadd mysql#useradd -g mysql -s /bin/false -M mysql#tar zxvf mysql-5.0.45.tar.gz

一、安装mysql-5.0.45

#groupadd mysql
#useradd -g mysql -s /bin/false -M mysql
#tar zxvf mysql-5.0.45.tar.gz
#cd mysql-5.0.45

#./configure
--prefix=/usr/local/mysql
--enable-thread-safe-client
--enable-local-infile
--with-charset=gbk
--with-extra-charset=all
--with-low-memory
#make
#make install
#cp support-files/my-medium.cnf /etc/my.cnf
#cd /usr/local/mysql
#chown -R mysql .
#chgrp -R mysql .
#bin/mysql_install_db --user=mysql
#chown -R root .
#chown -R mysql var
#bin/mysqld_safe --user=mysql &

#cd /usr/local/src/mysql-5.0.45 (这里的目录指的是原压缩包解压后的目录)
#cp support-files/mysql.server /etc/rc.d/init.d/mysqld
#chmod 700 /etc/rc.d/init.d/mysqld
加入自动启动服务队列：
#chkconfig --add mysqld
#chkconfig --level 345 mysqld on

测试
#/usr/local/mysql/bin/mysqladmin ping
#/usr/local/mysql/bin/mysqladmin version
#/usr/local/mysql/bin/mysql

添加root密码
#/usr/local/mysql/bin/mysqladmin -uroot -p 旧密码 password 新密码
说明：此时mysql的root用户的密码为空

配置库文件搜索路径
# echo "/usr/local/mysql/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/mysql/bin


二、安装openssl-0.9.8e

# tar zxvf openssl-0.9.8e.tar.gz
# cd openssl-0.9.8e
# ./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
OpenSSL 0.9.8e 23 Feb 2007


三.安装cyrus-sasl

# tar zxvf cyrus-sasl-2.1.26.tar.gz
# cd cyrus-sasl-2.1.26
# ./configure --prefix=/usr/local/sasl2 --disable-gssapi --disable-anon --disable-sample --disable-digest --enable-plain --enable-login --enable-sql --with-mysql=/data/program/developDB --with-mysql-includes=/data/program/developDB/include/mysql --with-mysql-libs=/data/program/developDB/lib --with-authdaemond=/usr/local/courier-authlib/var/spool/authdaemon/socket
# make
# make install

如果系统已有sasl,则关闭原有的sasl：
# mv /usr/lib/libsasl2.a /usr/lib/libsasl2.a.OFF
# mv /usr/lib/libsasl2.la /usr/lib/libsasl2.la.OFF
# mv /usr/lib/libsasl2.so.2.0.19 /usr/lib/libsasl2.so.2.0.19.OFF
# mv /usr/lib/sasl2 /usr/lib/sasl2.OFF
# rm /usr/lib/libsasl2.so
# rm /usr/lib/libsasl2.so.2

# ln -sv /usr/local/sasl2/lib/* /usr/lib

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：
# ln -sv /usr/local/sasl2/lib/* /usr/local/lib
# ln -sv /usr/local/sasl2/include/sasl/* /usr
