我们需要下载libevent和memcached这两个压缩包进行安装，可使用以下百度网盘链接进行下载

默认将以上文件下载到root家目录下
1.提前安装好依赖
yum install -y apr* autoconf automake bison cloog-ppl compat* cpp curl curl-devel fontconfig fontconfig-devel freetype
freetype* freetype-devel gcc gcc-c++ gtk+-devel gd gettext gettext-devel glibc kernel kernel-headers keyutils keyutils-libs-devel
krb5-devel libcom_err-devel libpng* libjpeg* libsepol-devel libselinux-devel libstdc++-devel libtool* libgomp libxml2 libxml2-devel
libXpm* libtiff libtiff* libX* make mpfr ncurses* ntp openssl openssl-devel patch pcre-devel perl php-common php-gd policycoreutils
ppl telnet t1lib t1lib* nasm nasm* wget zlib-devel gmp-devel
2.解压和安装libevent和memcached
tar -zxvf libevent-2.0.22-stable.tar.gz cd libevent-2.0.22-stable ./configure --prefix=/usr/local/libevent make make install cd tar -zxvf memcached-1.4.25.tar.gz cd memcached-1.4.25 ./configure --prefix=/usr/local/memcached -with-libevent=/usr/local/libevent make make install
3.启动memcached。注意：-l需要输入本机ip地址
groupadd memcached useradd -g memcached memcached -s /bin/false ln -s /usr/local/memcached/bin/memcached /usr/local/bin/memcached /usr/local/memcached/bin/memcached -d -m 4096 -u root -l 172.16.1.188 -p 11211 -c 1024 -P /usr/local/memcached/memcached.pid
4.检测memcached是否运行正常，端口有在监听就是运行着的
netstat -tlnp|grep 11211
5.测试memcached
telnet 172.16.1.188 11211
红色箭头所指就是我输入的东西。大概意思是设置了一个长度为7的test变量，其值为example，可以看到，我输入get test后，获取到了test的值example
