centos系统为php安装memcached扩展

这篇文章主要介绍了centos系统为php安装memcached扩展的步骤,大家参考使用吧
       1. 通过yum安装

yum -y install memcached
#安装完成后执行:
memcached -h
#出现memcached帮助信息说明安装成功

2. 加入启动服务

chkconfig --level 2345 memcached on

3. 配置Memcached

vim /etc/sysconfig/memcached
#文件中内容如下，按需要修改:
PORT="11211" #端口
USER="root" #用户名
MAXCONN="1024" #最大连接数
CACHESIZE="64" #内存大小
OPTIONS="" #附加参数

4. 安装libmemached

wget https://launchpad.net/libmemcached/1.0/1.0.16/+download/libmemcached-1.0.16.tar.gz
tar -zxvf libmemcached-1.0.16.tar.gz
cd libmemcached-1.0.16
./configure -prefix=/usr/local/libmemcached -with-memcached
make && make install
注意:这里容易报错，
编译错误：
libmemcached/auto.cc: In function 'memcached_return_t text_incr_decr(memcached_server_st*, bool, const char*, size_t, uint64_t, bool)':
libmemcached/auto.cc:73: error: expected `)' before 'PRIu64'

In file included from ./libmemcached/common.h:72,
from ./libmemcached/csl/common.h:40,
from libmemcached/csl/context.cc:38:
./libmemcached-1.0/memcached.h:46:27: error: tr1/cinttypes: No such file or directory
原因是gcc版本过低了
对策：libmemcached-1.0.2 版本以上升级编译器版本
# yum install gcc44 gcc44-c++ libstdc++44-devel

# export CC=/usr/bin/gcc44
# export CXX=/usr/bin/g++44
# ./configure

如果升级gcc版本出现连接源的问题不能下载，可以换用163的yum源，参考文章

5. 安装php-devel

yum install php-devel

6. 安装PHP Memcached扩展

wget http://pecl.php.net/get/memcached-2.1.0.tgz
tar -zxvf memcached-2.1.0.tgz
cd memcached-2.1.0
/usr/local/php/bin/phpize
./configure -enable-memcached -with-php-config=/usr/local/php/bin/php-config -with-zlib-dir -with-libmemcached-dir=/usr/local/libmemcached -prefix=/usr/local/phpmemcached
make && make install
