编译环境:centos7.9
依赖安装:
yum install curl gcc gcc-c++ openssl openssl-devel pcre-devel bzip2-devel systemd-devel |
---|
离线安装:
yum localinstall *.rpm -y |
---|
创建无home也无法登录的用户:
useradd -s /sbin/nologin -M haproxy |
---|
下载解压:
curl —progress https://codeload.github.com/haproxy/haproxy/tar.gz/refs/tags/v2.5.0 | tar xz cd haproxy-2.5.0 uname -a make TARGET=linux310 ARCH=x86_64 USE_SYSTEMD=1 USE_CPU_AFFINITY=1 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 make install cp haproxy /usr/sbin/ mkdir -p /usr/local/haproxy/log touch /usr/local/haproxy/log/haproxy.log |
---|
# USE_PCRE=1 开启正则 USE_OPENSSL=1 开启openssl USE_ZLIB=1
# # 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。
可以使用PREFIX=/usr/local/haproxy指定安装位置
默认安装位置:/usr/local/sbin/haproxy
卸载:make uninstall
准备系统启动脚本
cp examples/haproxy.init /etc/init.d/haproxy chmod 755 /etc/init.d/haproxy chkconfig —add haproxy make -C admin/systemd/ cp admin/systemd/haproxy.service /lib/systemd/system/haproxy.service |
---|
系统配置文件:
vi /etc/sysconfig/haproxy # Add extra options to the haproxy daemon here. This can be useful for # specifying multiple configuration files with multiple -f options. # See haproxy(1) for a complete list of options. OPTIONS=”” |
---|
配置各个负载的内核参数:
vim /etc/sysctl.conf net.ipv4.ip_nonlocal_bind=1 #开启允许绑定非本机的IP,haporxy启动忽视VIP存在 net.ipv4.ip_forward=1 #内核是否转发数据包 |
---|
配置内核参数生效:sysctl -p
配置文件:
mkdir /etc/haproxy mkdir /var/lib/haproxy mkdir /etc/haproxy/conf |
---|
复制配置文件:
cp examples/basic-config-edge.cfg /etc/haproxy/haproxy.cfg |
---|
配置文件:
