haproxy2.1.3-编译安装 centos7
haproxy2.1.3 下载
安装依赖:
yum install -y openssl openssl-devel systemd-devel.x86_64解压源码:
tar -zxf haproxy-2.1.3.tar.gz-
编译安装:
cd haproxy-2.1.3/ make TARGET=linux-glibc PREFIX=/usr/local/haproxy USE_OPENSSL=1 USE_SYSTEMD=1 USE_PCRE=1 USE_ZLIB=1 PREFIX=/usr/local/haproxy && make install开启https：
USE_OPENSSL=1指定为systemd模式:
USE_SYSTEMD=1指定安装目录:
PREFIX=/usr/local/haproxy-
注册到系统服务:
cp contrib/systemd/haproxy.service.in /usr/lib/systemd/system/haproxy.service vim /usr/lib/systemd/system/haproxy.service修改路径
[Service] ExecStartPre=/usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c -q ExecStart=/usr/local/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid ExecReload=/bin/kill -USR2 $MAINPID -
开启haproxy日志:
vim /etc/rsyslog.conf# Provides UDP syslog reception #解开注释 $ModLoad imudp #解开注释 $UDPServerRun 514 #添加 local0.* /var/log/haproxy.log编辑rsyslog
vim /etc/sysconfig/rsyslog SYSLOGD_OPTIONS="-r -m 0 -c 2" -
添加启动用户
useradd -r haproxy usermod -G haproxy haproxy -
创建配置文件及启动目录:
mkdir -p /var/lib/haproxy touch /var/lib/haproxy/stats mkdir /etc/haproxy vim /etc/haproxy/haproxy.cfg默认不生成 Example：
global log 127.0.0.1 local0 info chroot /var/lib/haproxy pidfile /var/run/haproxy.pid maxconn 1020 # See also: ulimit -n user haproxy group haproxy daemon # turn on stats unix socket stats socket /var/lib/haproxy/stats.sock mode 600 level admin stats timeout 2m defaults mode tcp log global option dontlognull option redispatch timeout http-request 10s retries 3 timeout queue 45s timeout connect 10s timeout client 1m timeout server 1m timeout http-keep-alive 10s timeout check 10s maxconn 1020 listen stats mode http bind 0.0.0.0:8089 stats enable stats uri /admin?stats stats realm Haproxy\ Statistics stats auth admin:admin stats admin if TRUE frontend mysql description "MySQL" bind *:3306 mode tcp log global default_backend mysql backend mysql description "MySQL" balance leastconn server mysql1 192.168.88.8:3307 check server mysql2 192.168.88.10:3307 check检验haproxy.cfg 是否正确:
haproxy -c -f /etc/haproxy/haproxy.cfg
待出现Configuration file is valid说明配置有效 -
重启服务
systemctl restart haproxy systemctl restart rsyslog ## 查看日志 tail /var/log/haproxy.log ## 开机自启 systemctl enable haproxy
