安装gcc环境yum -y install gcc+
确认开发环境已安装;
Development Libraries
Development Tools
启动mysqld数据库服务. service mysqld start
启动saslauthd服务 service saslauthd start
添加postsfix账户:groupadd -g 2525 postfix
useradd -g 2525 -u 2525 -s /sbin/nologin -M postfix
添加postdrop用户组 groupadd -g 2526 postdrop
useradd -g 2526 -u 2526 -s /sbin/nologin -M postdrop
开始安装postfix
3.解压源码包 tar xf postfix-2.10.8.tar.gz
2.进入解压后的文件夹执行:make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS ' 'AUXLIBS=-L/usr/local/mysql/lib -lmysqlclient -lz -lm -L/usr/lib/sasl2 -lsasl2 -lssl -lcrypto'
[*]说明:
-I/usr/local/mysql/include指明MySQl头文件路径
AUXLIBS=-L/usr/local/mysql/lib指明MySQL库文件路径
-DUSE_SASL_AUTH 启用SASL支持
-I/usr/include/sasl 指明SASL头文件路径
-DUSE_TLS支持SMTPS协议
makefile过程中可能遇到的错误:
*** 错误 127缺少gcc环境
3.make **make install
