配置haproxy及通过rsyslog记录日志

Zhaoyu Luo bio photo By Zhaoyu Luo

安装

推荐使用apt-get install haproxy里面自带了重新启动脚本

如果编译的话apt-get install libpcre3-dev的pcre可以大幅提高regex表达式的解析速度 然后make TARGET=generic USE_PCRE=1

配置

haproxy.cfg

global
        log 127.0.0.1   local0
        log 127.0.0.1   local1 notice
        #log loghost    local0 info
        maxconn 4096
        #chroot /usr/share/haproxy
        user sysop
        group sysop
        daemon
        #debug
        #quiet

defaults
        log     global
        mode    http
        option  httplog
        option  dontlognull
        option  httpclose # 很重要，确保http真的关闭
        option  forceclose # 没有关闭的强制关闭，保证兼容性
        retries 3
        option redispatch
        maxconn 2000
        contimeout      5000
        clitimeout      50000
        srvtimeout      50000

listen test 0.0.0.0:8000
        balance roundrobin
        server  server1 10.5.5.5:8001 check weight 30
        server  server2 10.5.5.5:8002 check weight 30
        server  server3 10.5.5.5:8003 check weight 30
        stats enable
        stats uri /stats
        stats refresh 3

rsyslog

首先让rsyslog监听514端口，其次是把haproxy的日志都打入特定文件 vim /etc/rsyslog.d/haproxy.conf

# Create an additional socket in haproxy's chroot in order to allow logging via
# /dev/log to chroot'ed HAProxy processes
$AddUnixListenSocket /tmp/haproxylog.sock
#local0.*                               /tmp/haproxy.log
#local1.*                               /tmp/haproxy.log

# Send HAProxy messages to a dedicated logfile
if $programname startswith 'haproxy' then /tmp/haproxy.log

调试rsyslog

logger -p local0.err thisisanerrormessage
