haproxy动静分离

在80.100虚拟机上：
systemctl stop firewalld //关闭防火墙
setenforce 0 //关闭监控
yum install lrz* -y //安装上传软件

tar xf haproxy-1.5.15.tar.gz -C /opt/ //解压压缩包
cd /opt/haproxy-1.5.15/
yum install -y \
pcre-devel \
bzip2-devel \
gcc \
gcc-c++ \
make

uname -r //内核版本

make TARGET=linux26 PREFIX=/usr/local/haproxy //标识64为系统
make install PREFIX=/usr/local/haproxy
mkdir /etc/haproxy //创建目录
useradd -s /sbin/nologin -M haproxy //创建用户
id haproxy //查看用户信息

cd /usr/local/haproxy/
cd /opt/haproxy-1.5.15/
cd examples/

cp haproxy.cfg /etc/haproxy/
cd /etc/haproxy/

vi haproxy.cfg

chroot /usr/share/haproxy前面加#
uid 1000
gid 1000    ...

srvtimeout      50000   后面的内容全删了，再添加以下内容
--------------统计页面配置------------------
 listen admin_stats       #为haproxy访问状态监控页面配置，取名为admin_stats
    bind 0.0.0.0:8089      //监听端口
    stats enable          //启用监听端口
    mode http         #http的7层模式
    log global         # 继承global中log的定义
    stats uri  /stats     #监控页面的url访问路径，即http://ip/stats 访问监控页面
    stats realm Haproxy\ Statistics     #监控页面的密码框提示信息
    stats auth  admin:admin          #监控页面的用户和密码admin,可以设置多个用户名
    #stats hide-version   //隐藏统计页面上HAProxy的版本信息
    stats admin if TRUE    //当通过认证才可管理
    stats refresh 30s    //页面自动刷新时间30s

:wq      //保存退出

cd -

cp haproxy.init /etc/init.d/haproxy
ll /etc/init.d/haproxy
chmod +x /etc/init.d/haproxy //给这个文件设置权限
ll /etc/init.d/haproxy

chkconfig --add haproxy
ln -s /usr/local/haproxy/sbin/haproxy /usr/sbin/haproxy //软链接
service haproxy start
netstat -anp | grep haproxy
在网页上输入http://192.168.80.100:8089/stats

vi /etc/haproxy/haproxy.cfg 最后一行添加以下内容
