一、部署haproxy

官网： https://www.haproxy.org/download/2.0/src/

[root@test ~]# wget  https://www.haproxy.org/download/2.0/src/haproxy-2.0.12.tar.gz

二、解压并查看

[root@test ~]# tar xf haproxy-2.0.12.tar.gz -C /opt/
[root@test /opt]# cd /opt/haproxy-2.0.12/
[root@test /opt/haproxy-2.0.12]# ls
BRANCHES   contrib       doc     examples  INSTALL  MAINTAINERS  README     ROADMAP  src      tests    VERSION
CHANGELOG  CONTRIBUTING  ebtree  include   LICENSE  Makefile     reg-tests  scripts  SUBVERS  VERDATE

三、编译安装

# 1、安装依赖
[root@test /opt/haproxy-2.0.12]# yum install gcc gcc-c++ glibc glibc-devel pcre pcre-devel openssl  openssl-devel systemd-devel vim iotop bc  zip unzip zlib-devel lrzsz tree screen lsof tcpdump wget ntpdate -y

# 2、编译
[root@test /opt]# mkdir haproxy
[root@test /opt/haproxy-2.0.12]# pwd
/opt/haproxy-2.0.12
[root@test /opt/haproxy-2.0.12]# make  ARCH=x86_64 TARGET=linux-glibc USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1  USE_CPU_AFFINITY=1  PREFIX=/opt/haproxy
[root@test /opt/haproxy-2.0.12]# make install PREFIX=/opt/haproxy
[root@test /opt/haproxy-2.0.12]# cp haproxy /usr/sbin/
# 3、查看版本
[root@test /opt/haproxy-2.0.12]# haproxy -v
HA-Proxy version 2.0.12 2019/12/21 - https://haproxy.org/

四、配置文件

[root@test /opt/haproxy-2.0.12]#  vim /usr/lib/systemd/system/haproxy.service
[Unit]
Description=HAProxy Load Balancer
After=syslog.target network.target
[Service]
ExecStartPre=/usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -f /etc/haproxy/conf -c -q
ExecStart=/usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -f /etc/haproxy/conf -p /run/haproxy.pid
ExecReload=/bin/kill -USR2 $MAINPID
[Install]
WantedBy=multi-user.target

五、创建haproxy的所需目录

[root@test /opt/haproxy-2.0.12]# mkdir -p /etc/haproxy && mkdir -p /etc/haproxy/con

六、创建haproxy启动配置文件

[root@test /opt/haproxy-2.0.12]# vim /etc/haproxy/haproxy.cfg 
global
maxconn 100000
chroot /opt/haproxy
#stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin
uid 99
gid 99
daemon
# 绑定CPU核心数
nbproc 2
cpu-map 1 0
cpu-map 2 1
pidfile /opt/haproxy/run/haproxy.pid
log 127.0.0.1 local3 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    admin:admin
listen  web_port
 bind 0.0.0.0:80
 mode http
 log global
 server web1  127.0.0.1:8080  check inter 3000 fall 2 rise 5

七、启动haproxy服务

# 由于在/usr/lib/systemd/system/下新加了haproxy.service启动文件需要reload
[root@test /opt/haproxy-2.0.12]# systemctl daemon-reload
[root@test /opt/haproxy-2.0.12]# systemctl start haproxy

八、查看服务是否启动

[root@test /opt/haproxy-2.0.12]#  ps -ef | grep haproxy
root       1978      1  0 12:00 ?        00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -f /etc/haproxy/conf -p /run/haproxy.pid
nobody     1980   1978  0 12:00 ?        00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -f /etc/haproxy/conf -p /run/haproxy.pid
nobody     1981   1978  0 12:00 ?        00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -f /etc/haproxy/conf -p /run/haproxy.pid
root       1983   1067  0 12:00 pts/0    00:00:00 grep --color=auto haproxy

九、知识补充

# 上传过程就省略掉了
[root@test ~]# tar xf haproxy-2.0.12.tar.gz -C /opt/
[root@test /opt]# cd /opt/haproxy-2.0.12/
# USE_CPU_AFFINITY=1 为开启haproxy进程与CPU核心绑定，USE_SYSTEMD=1为支持使用 -Ws参数（systemd-aware master-worker 模式）启动Haproxy，从而实现单主进程多子进程运行模式。在2.0后TARGET=linux2628 被剔除掉了如果继续用的话就会报错
[root@test  haproxy-2.0.13]# make  ARCH=x86_64 TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1  USE_CPU_AFFINITY=1  PREFIX=/usr/local/haproxy
Target 'linux2628' was removed from HAProxy 2.0 due to being irrelevant and
often wrong. Please use 'linux-glibc' instead or define your custom target
by checking available options using 'make help TARGET=<your-target>'.
make: *** [all] Error 1
# 解决方法是把TARGET=linux2628替换成TARGET=linux-glibc
[root@test  haproxy-2.0.13]# make  ARCH=x86_64 TARGET=linux-glibc USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1  USE_CPU_AFFINITY=1  PREFIX=/usr/local/haproxy
[root@test  haproxy-2.0.13]# make install PREFIX=/opt/haproxy
# 编译完成之后会在当前目录中生成一个可执行程序复制到/usr/sbin下
[root@test  haproxy-2.0.13]# cp haproxy /usr/sbin/
