开始安装

yum install libevent-devel libevent

mkdir magent cd magent/

tar-zxf magent-0.6.tar.gz

/sbin/ldconfig

sed -i "s#LIBS = -levent#LIBS = -levent -lm#g" Makefile

make

cp magent /usr/bin/magent

0.6make错误多，可用0.5版

安装时错误解决方法

make时报错

magent.c: In function ‘writev_list’: magent.c:729: error: ‘SSIZE_MAX’ undeclared (first use in this function) magent.c:729: error: (Each undeclared identifier is reported only once magent.c:729: error: for each function it appears in.) make: ***[magent.o] Error 1

解决：

vim ketama.h 在开头加入    

#ifndef SSIZE_MAX

#define SSIZE_MAX      32767

#endif

再次make报错：

gcc: /usr/lib64/libevent.a: No such file or directory gcc: /usr/lib64/libm.a: No such file or directory

解决：

vi Makefile 找到 LIBS = /usr/lib64/libevent.a /usr/lib64/libm.a这一行 将libevent 的安装路径修改为/usr/local/lib/ libevent.a 或者ln-s/usr/local/lib/libevent*/usr/lib64/   ln-s/usr/lib64/libm.so /usr/lib64/libm.a

再次make报错:

/usr/local/lib/libevent.a(event.o): In function`gettime': undefined reference to `clock_gettime' collect2: ld returned 1exit status

解决：

vim Makefile 将   CFLAGS = -Wall-g-O2 -I/usr/local/include $(M64) 改为：     CFLAGS = -lrt-Wall-g-O2 -I/usr/local/include $(M64)

删除临时文件rm -rf *.o后

再次make成功生成magent

最后cp magent /usr/bin/magent
