HAProxy编译安装

首先上官网获取haproxy的tar包

解压至当前目录

    haproxy的配置文件中要使用到haproxy用户

    所以我们先创建该用户

    useradd -r  -s /sbin/nologin haproxy
    tar xf haproxy-1.8.13.tar.gz
    cd haproxy-1.8.13/

    vim README 文档
    其中我们可以查看到关于怎么样安装 

我们使用其中的一项，包括了pcre 和 ssl 以及zlib等功能 

$ make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 PREFIX=/usr/local/haproxy

make install PREFIX=/usr/local/haproxy

make install的时候要带上PREFIX= ... 不然它会直接在/usr/local/目录下安装相关的文件

cp /haproxy-1.8.13/examples/haproxy.init /etc/rc.d/haproxy
vim /etc/rc.d/haproxy

修改其中的一行，这是其中的一个坑


[ ${NETWORKING} = "no" ] && exit 0

[ "${NETWORKING}" = "no" ] && exit 0  给${NETWORKING}加上引号

接下来我们要自行创建haproxy的配置文件

mkdir /etc/haproxy
vim /etc/haproxy/haproxy.cfg

 我在1.5版的haproxy的rpm包版本里取得了配置文件

    # to have these messages end up in /var/log/haproxy.log you will
    # need to:
    #
    # 1) configure syslog to accept network log events.  This is done
    #    by adding the '-r' option to the SYSLOGD_OPTIONS in
    #    /etc/sysconfig/syslog
    #
    # 2) configure local2 events to go to the /var/log/haproxy.log
    #   file. A line like the following can be added to
    #   /etc/sysconfig/syslog
    #
    #    local2.*                       /var/log/haproxy.log

    server  app3 127.0.0.1:5003 check
    server  app4 127.0.0.1:5004 check

这是未改动过的版本

 其中还是有一个坑

在frontend段，好像1.8.13版本只能支持bind绑定端口号所以应该去掉main后面的*:5000，在其下一行加上bind  *:80

这个时候还不能开启haproxy服务，如果开启，会报一个

cannot bind UNIX socket [/var/lib/haproxy/stats

 的错误。（超级坑！！！）

这个时候需要自行创建/var/lib/haproxy目录，并将权限给haproxy用户

mkdir /var/lib/haproxy
chown haproxy:haproxy /var/lib/haproxy

这个时候就完成了haproxy的简单的编译安装！！

可以再frontend调用backend实现负载均衡了
