haproxy2.1.3-编译安装

haproxy2.1.3-编译安装 centos7

1. haproxy2.1.3 下载

2. 安装依赖:
   yum install -y openssl openssl-devel systemd-devel.x86_64

3. 解压源码:
   tar -zxf haproxy-2.1.3.tar.gz

4. 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
