安装memcache集群管理工具magent
一、安装libevent
tar xf libevent-2.0.20-stable.tar.gz
cd libevent-2.0.20
./configure --prefix=/usr/local/libevent
make && make install
echo "/usr/local/libevent/lib" > /etc/ld.so.conf.d/libevent.conf
ldconfig二、安装magent
mkdir /usr/local/magent
tar xf magent-0.5.tar.gz -C /usr/local/magent
/sbin/ldconfig
cd /usr/local/magent/
vim Makefile
LIBS = -levent -lm -L /usr/local/libevent/lib
INCLUDE = -I /usr/local/libevent/include
CFLAGS = -Wall -O2 -g
CC = gcc
PROGS = magent
..........(以下省略)
vim ketama.h (在文件起始行加下以下代码)
#ifndef SSIZE_MAX
#define SSIZE_MAX 32767
#endif
ln -sv /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib/
cp magent /usr/bin/magent查看是否安装成功及使用
