操作系统：CentOS 7.x 64位
实现目的：安装部署Memcached服务器
一、防火墙设置
CentOS 7.x默认使用的是firewall作为防火墙，这里改为iptables防火墙。
1、关闭firewall：
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
2、安装iptables防火墙
yum install iptables-services #安装
vi /etc/sysconfig/iptables #编辑防火墙配置文件
# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 11211 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
:wq! #保存退出
systemctl restart iptables.service #最后重启防火墙使配置生效
systemctl enable iptables.service #设置防火墙开机启动
/usr/libexec/iptables/iptables.init restart #重启防火墙
二、关闭SELINUX
vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
setenforce 0 #使配置立即生效
三 、系统约定
软件源代码包存放位置：/usr/local/src
源码包编译安装位置：/usr/local/软件名字
四、下载软件包
1、下载libevent
http://ftp.lfs-matrix.net/pub/blfs/conglomeration/libevent/libevent-2.0.22-stable.tar.gz
2、下载memcached
http://memcached.org/files/memcached-1.4.34.tar.gz
五、安装编译工具包
yum install -y apr* autoconf automake bison bzip2 bzip2* 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 libpng-devel libjpeg* libsepol-devel libselinux-devel libstdc++-devel libtool* libgomp libxml2 libxml2-devel libXpm* libxml* libtiff libtiff* make mpfr ncurses* ntp openssl openssl-devel patch pcre-devel perl php-common php-gd policycoreutils telnet t1lib t1lib* nasm nasm* wget zlib-devel
六、安装配置memcached
1、安装libevent
cd /usr/local/src
tar zxvf libevent-2.0.22-stable.tar.gz
cd libevent-2.0.22-stable
./configure --prefix=/usr/local/libevent
make
make install
2、安装memcached
cd /usr/local/src
tar zxvf memcached-1.4.34.tar.gz
cd memcached-1.4.34
