由于HAProxy的运行信息不写入日志文件,但它依赖于标准的系统日志协议将日志发送到远程服务器(通常位于同一系统上),所以需要借助rsyslog来收集haproxy的日志.haproxy代理nginx的访问,使用logstash收集nginx的访问信息.
1.安装配置haproxy
yum -y install gcc pcre pcre-devel openssl openssl-devel cd /usr/local/src/ wget https://www.haproxy.org/download/1.7/src/haproxy-1.7.11.tar.gz tar xf haproxy-1.7.11.tar.gz cd haproxy-1.7.11/ make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 PREFIX=/usr/local/haproxy make install PREFIX=/usr/local/haproxy /usr/local/haproxy/sbin/haproxy -v cat /usr/lib/systemd/system/haproxy.service [Unit] Description=HAProxy Load Balancer After=syslog.target network.target [Service] EnvironmentFile=/etc/sysconfig/haproxy ExecStart=/usr/sbin/haproxy-systemd-wrapper -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid $OPTIONS ExecReload=/bin/kill -USR2 $MAINPID [Install] WantedBy=multi-user.target cat /etc/sysconfig/haproxy # Add extra options to the haproxy daemon here. This can be useful for # specifying multiple configuration files with multiple -f options. # See haproxy(1) for a complete list of options. OPTIONS="" cp /usr/local/src/haproxy-1.7.11/haproxy /usr/sbin/ cp /usr/local/src/haproxy-1.7.11/haproxy-systemd-wrapper /usr/sbin/
2.准备haproxy配置文件
mkdir /etc/haproxy
cat /etc/haproxy/haproxy.cfg
global
maxconn 100000
chroot /usr/local/haproxy
uid 1000
gid 1000
daemon
nbproc 1
pidfile /usr/local/haproxy/run/haproxy.pid
log 127.0.0.1 local6 info
defaults
option http-keep-alive
option forwardfor
maxconn 100000
mode http
timeout connect 300000ms
timeout client 300000ms
timeout server 300000ms
listen stats
mode http
bind 0.0.0.0:9999
stats enable
log global
stats uri /haproxy-status
stats auth haadmin:123456

option httplog
log global
option forwardfor
#ACL Setting

useradd haproxy -M -s /sbin/nologin --uid 1000
id haproxy
uid=1000(haproxy) gid=1000(haproxy) groups=1000(haproxy)
systemctl start haproxy.service
ss -tnl # 查看80端口是否启动
# haproxy不允许ip直接访问80端口,修改windows的hosts,win+r-->drivers快速打开hosts
10.0.0.22 www.elk1.com
10.0.0.22 m.elk1.com
这里让haproxy代理nginx,将nginx的监听端口改为88并启动,使用www.elk.com,无法跳转到我想要的页面,所以改成了www.elk1.com

访问http://www.elk1.com/nginxweb/

3.配置rsyslog记录haproxy日志
vim /etc/rsyslog.conf # 打开15,16,19,20行注释
$ModLoad imudp
$UDPServerRun 514
$ModLoad imtcp
$InputTCPServerRun 514
# 文件末尾添加haproxy中配置的对应日志级别
local6.* /var/log/haproxy/haproxy.log # 日志记录文件
local6.* @@10.0.0.22:5160 # 本地IP和监听端口
mkdir /var/log/haproxy
chown -R haproxy.haproxy /var/log/haproxy
systemctl restart rsyslog
systemctl restart haproxy
cat /etc/logstash/conf.d/haproxy_log.conf
input {
syslog{
type => "haproxy1022"
port => "5160"
}
}
output{
stdout{
codec => "rubydebug"
}
}
port => "5160"监听rsyslog中定义的local6端口,小于1024可能会报错
/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/haproxy_log.conf

logstash收集rsyslog传过来的日志
cat haproxy_log.conf
input {
syslog{
type => "haproxy1022"
port => "5160"
}
}
output{
if [type] == "haproxy1022" {
elasticsearch {
hosts => ["10.0.0.22:9200"]
index => "logstash-haproxy1022-%{+YYYY.MM.dd}"
}
}
}
systemctl restart logstash.service
