编译安装haproxy2.0

先解决lua环境，（因为centos自带的版本不符合haproxy要求的最低版本（5.3）先安装Lua依赖的包

[root@slave-master lua-5.3.5]# yum install  vim iotop bc gcc gcc-c++ glibc glibc-devel pcre pcre-devel openssl  openssl-devel zip unzip zlib-devel  net-tools lrzsz tree ntpdate telnet lsof tcpdump wget libevent libevent-devel bc  systemd-devel bash-completion traceroute -y
[root@slave-master lua-5.3.5]# yum install libtermcap-devel ncurses-devel libevent-devel readline-devel  -y

 

下载lua并编译安装

[root@slave-master haproxy-2.0.4]# cd /usr/local/src/
[root@slave-master src]# tar xf lua-5.3.5.tar.gz
[root@slave-master src]# cd lua-5.3.5
[root@slave-master lua-5.3.5]# make linux test
[root@slave-master lua-5.3.5]# src/lua -v

下载haproxy并编译安装

[root@slave-master src]# tar xf haproxy-2.0.4.tar.gz -C /usr/local/
[root@slave-master src]# cd /usr/local/haproxy
[root@slave-master haproxy-2.0.4]# make ARCH=x86_64 TARGET=linux-glibc USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 USE_CPU_AFFINITY=1 USE_LUA=1 LUA_INC=/usr/local/src/lua-5.3.5/src/ LUA_LIB=/usr/local/src/lua-5.3.5/src/ PREFIX=/usr/local/haproxy
[root@slave-master haproxy-2.0.4]# make install PREFIX=/usr/local/haproxy
[root@slave-master haproxy-2.0.4]# cp haproxy /usr/sbin/

 

准备启动脚本

[root@slave-master haproxy]# 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 -c -q
ExecStart=/usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /var/lib/haproxy/haproxy.pid
ExecReload=/bin/kill -USR2 $MAINPID
[Install]
WantedBy=multi-user.target

 

准备配置文件

[root@slave-master haproxy]# mkdir /etc/haproxy/
[root@slave-master haproxy]# vim /etc/haproxy/haproxy.cfg

启动服务

[root@slave-master src]# mkdir /var/lib/haproxy
[root@slave-master src]# chown 99.99 /var/lib/haproxy/ -R
[root@slave-master haproxy]# systemctl start haproxy
