准备一台haproxy（192.168.200.115），两台nginx
一、安装nginx（192.168.200.111/112）
[root@localhost ~]# yum -y install pcre-devel zlib-devel openssl-devel [root@localhost ~]# yum -y install gcc gcc-c++ make [root@localhost ~]# useradd -M -s /sbin/nologin nginx [root@localhost ~]# tar -xf nginx-1.15.9.tar.gz -C /usr/src/ [root@localhost ~]# cd /usr/src/nginx-1.15.9/ [root@localhost ~]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx && make && make install [root@localhost ~]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/ [root@localhost ~]# nginx [root@localhost ~]# netstat -lnpt | grep :80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 13144/nginx: master
写一个测试文件
第一台[root@localhost ~]# echo "aaaaa" > /usr/local/nginx/html/index.html
第二台 [root@localhost ~]# echo "bbbbbb" > /usr/local/nginx/html/index.html
二、安装配置Haproxy（192.168.200.115）
1、安装Haproxy依赖包及源码编译安装
1 [root@localhost ~]# yum -y install gcc gcc-c++ make pcre-devel bzip2-devel [root@localhost ~]# tar -xf haproxy-1.4.24.tar.gz -C /usr/src/ 2 [root@localhost ~]# cd /usr/src/haproxy-1.4.24/ 3 [root@localhost haproxy-1.4.24]# make TARGET=linux26 && make install
2、建立haproxy的配置目录及文件
[root@localhost haproxy-1.4.24]# mkdir /etc/haproxy [root@localhost haproxy-1.4.24]# cp examples/haproxy.cfg /etc/haproxy
3、haproxy 配置文件修改
8 [root@localhost ~]# vim /etc/haproxy/haproxy.cfg 9 # this config needs haproxy-1.1.28 or haproxy-1.2.1 10 11 global 12 # log 127.0.0.1 local0 13 # log 127.0.0.1 local1 notice 14 log /dev/log local0 info 15 log /dev/log local0 notice 16 maxconn 4096 17 uid 99 18 gid 99 19 daemon 20 21 defaults 22 log global 23 mode http 24 option httplog 25 retries 3 26 maxconn 4096 27 contimeout 5000 28 clitimeout 50000 29 srvtimeout 50000 30 31 listen webcluster 0.0.0.0:80 32 option httpchk GET /index.html 33 balance roundrobin 34 server inst1 192.168.200.111:80 check inter 2000 fall 3 35 server inst1 192.168.200.112:80 check inter 2000 fall 3 36 37 listen admin_stats 38 bind 0.0.0.0:8000 39 mode http 40 option httplog 41 maxconn 100 42 stats refresh 1s 43 stats uri /stats 44 stats realm Crushlinux\ Haproxy 45 stats auth admin:admin 46 stats hide-version 47
4、启动服务自启动脚本
[root@localhost ~]# cp /usr/src/haproxy-1.4.24/examples/haproxy.init /etc/init.d/haproxy [root@localhost ~]# ln -s /usr/local/sbin/haproxy /usr/sbin/haproxy [root@localhost ~]# chmod +x /etc/init.d/haproxy [root@localhost ~]# /etc/init.d/haproxy start
三、测试
[root@localhost ~]# while : > do > curl 192.168.200.115 > sleep 1 > done aaaaa bbbbbb aaaaa bbbbbb aaaaa bbbbbb 。。。。。。。。。。
