# 源码安装Haproxy1.8.0详细版 #

你好！ 本文将介绍如何在Linux编译源码安装haproxy1.8.0，你也许会遇到同样的问题，如果在ubuntu系统下问题可能会更多， 本文系统环境如下，如果你使用的是CentOS7.2也适用。

## 下载haproxy ##

haproxy1.8.0下载可以从官网直接下载： http://www.haproxy.org/ 参考截图：

检查下载的包是否完整：

root@ubuntu:~# cat haproxy-1.8.0.tar.gz.md5
    6ccea4619b7183fbcc8c98bae1f9823d  haproxy-1.8.0.tar.gz
    root@ubuntu:~# md5sum haproxy-1.8.0.tar.gz
    6ccea4619b7183fbcc8c98bae1f9823d  haproxy-1.8.0.tar.gz

如果你下载不了，可以通过百度网盘来下载：

## 编译安装 ##

### 创建用户 ###

# -M：不要自动建立用户的登入目录 -s：指定用户登入后所使用的shell
     root@ubuntu:~# useradd -M -s /sbin/nologin haproxy

### 安装依赖包 ###

# ubuntu-16.04系统请安装如下依赖，后面编译SSL/TLS支持,（PCRE）正则匹配支持、systemd服务支持需要
     root@ubuntu:~# apt-get install -y libssl-dev
     root@ubuntu:~# apt-get install -y libpcre3-dev
     root@ubuntu:~# apt-get install -y libsystemd-dev
    
     # CentOs-7.2系统请安装如下依赖，后面编译SSL/TLS支持,（PCRE）正则匹配支持、systemd服务支持需要
     root@centos:~# yum install -y pcre-devel
     root@centos:~# yum install -y openssl-devel
     root@centos:~# yum install -y systemd-devel

### 查看系统版本 ###

root@ubuntu:~# uname -r
     4.4.0-87-generic

### 检查对应的版本参数 ###

root@ubuntu:~/haproxy-1.8.0# vim README
    To build haproxy, you have to choose your target OS amongst the following ones
    and assign it to the TARGET variable :
    
      - linux22     for Linux 2.2
      - linux24     for Linux 2.4 and above (default)
      - linux24e    for Linux 2.4 with support for a working epoll (> 0.21)
      - linux26     for Linux 2.6 and above
      - linux2628   for Linux 2.6.28, 3.x, and above (enables splice and tproxy)
      - solaris     for Solaris 8 or 10 (others untested)
      - freebsd     for FreeBSD 5 to 10 (others untested)
      - netbsd      for NetBSD
      - osx         for Mac OS/X
      - openbsd     for OpenBSD 5.7 and above
      - aix51       for AIX 5.1
      - aix52       for AIX 5.2
      - cygwin      for Cygwin
      - haiku       for Haiku
      - generic     for any other OS or version.
      - custom      to manually adjust every setting

这里写得很清楚了，如果是2.6.28， 3.x及以上版本使用 linux2628参数

### 编译 ###

root@ubuntu:~/haproxy-1.8.0# make clean
    root@ubuntu:~/haproxy-1.8.0# make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 PREFIX=/usr/local/haproxy

正常能编译成功，如果编译过程出现问题，请根据具体日志排查，或者你可以尝试最小化编译

root@ubuntu:~/haproxy-1.8.0# make clean
     root@ubuntu:~/haproxy-1.8.0# make TARGET=linux2628 USE_SYSTEMD=1 PREFIX=/usr/local/haproxy

### 安装 ###

root@ubuntu:~/haproxy-1.8.0# make install PREFIX=/usr/local/haproxy
    install -d "/usr/local/haproxy/sbin"
    install haproxy  "/usr/local/haproxy/sbin"

    install -m 644 doc/haproxy.1 "/usr/local/haproxy/share/man"/man1

### 复制命令 ###

root@ubuntu:~/haproxy-1.8.0# cp -rf /usr/local/haproxy/sbin/haproxy /usr/sbin/
    root@ubuntu:~/haproxy-1.8.0# haproxy -v
    HA-Proxy version 1.8.0 2017/11/26

### 创建启动脚本 ###

root@ubuntu:~/haproxy-1.8.0# cp -rf ./examples/haproxy.init /etc/init.d/haproxy
    root@ubuntu:~/haproxy-1.8.0# chmod 755 /etc/init.d/haproxy

### 创建配置文件 ###

root@ubuntu:~/haproxy-1.8.0# mkdir -p /etc/haproxy/
    root@ubuntu:~/haproxy-1.8.0# vim /etc/haproxy/haproxy.cfg

### 创建haproxy目录 ###

root@ubuntu:~/haproxy-1.8.0# mkdir -p /var/lib/haproxy
    root@ubuntu:~/haproxy-1.8.0# chown haproxy:haproxy /var/lib/haproxy

### 检查haproxy.service文件 ###

root@ubuntu:~/haproxy-1.8.0# cat /run/systemd/generator.late/haproxy.service
    # Automatically generated by systemd-sysv-generator
    
    [Unit]
    Documentation=man:systemd-sysv-generator(8)
    SourcePath=/etc/init.d/haproxy
    Description=SYSV: HA-Proxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments.
    
    [Service]
    Type=forking
    Restart=no
    TimeoutSec=5min
    IgnoreSIGPIPE=no
    KillMode=process
    GuessMainPID=no
    RemainAfterExit=no
    PIDFile=/var/run/haproxy.pid
    ExecStart=/etc/init.d/haproxy start
    ExecStop=/etc/init.d/haproxy stop
    ExecReload=/etc/init.d/haproxy reload

这个haproxy.service文件是编译时指定USE\_SYSTEMD=1自动生成的，一般不需要改动。 如果没有请手动创建。

### 启动服务 ###

如果你是centos系统启动会很顺利，如果是ubuntu系统可能启动后会是这样：

root@ubuntu:~/haproxy-1.8.0# systemctl start haproxy
    Job for haproxy.service failed because a configured resource limit was exceeded. See "systemctl status haproxy.service" and "journalctl -xe" for details.

    2月 22 08:58:28 pg-primary systemd[1]: haproxy.service: Failed with result 'resources'.

提示 PID file /var/run/haproxy.pid not readable (yet?) after start: No such file or directory，你可能猜测跟权限有关？ 或者配置路径哪里不对？ 其实问题是 /etc/init.d/haproxy 脚本在ubuntu系统不能支持。 我们来看下这个脚本：

root@ubuntu:~/haproxy-1.8.0# vim /etc/init.d/haproxy
    
    #!/bin/sh
    #
    # chkconfig: - 85 15
    # description: HA-Proxy is a TCP/HTTP reverse proxy which is particularly suited \
    # for high availability environments.
    # processname: haproxy
    # config: /etc/haproxy/haproxy.cfg
    # pidfile: /var/run/haproxy.pid
    
    # Script Author: Simon Matter <simon.matter@invoca.ch>
    # Version: 2004060600
    
    # Source function library.
    if [ -f /etc/init.d/functions ]; then
      . /etc/init.d/functions
    elif [ -f /etc/rc.d/init.d/functions ] ; then
      . /etc/rc.d/init.d/functions
    else
      exit 0
    fi

这里脚本开头导入 /etc/init.d/functions 或 /etc/rc.d/init.d/functions文件，如果不存在则直接退出，脚本不运行，那么ubuntu16.04这个functions脚本位置其实在： /lib/lsb/init-functions ， 修改上面脚本为

# Source function library.
    if [ -f /etc/init.d/functions ]; then
      . /etc/init.d/functions
    elif [ -f /etc/rc.d/init.d/functions ] ; then
      . /etc/rc.d/init.d/functions
     # ubuntu16.04 support
    elif [ -f /lib/lsb/init-functions ] ; then
      . /lib/lsb/init-functions  
    else
      exit 0
    fi

再次启动试试

可以看到这次的报错信息跟上次不同，提示Can’t open /etc/sysconfig/network， 在ubuntu16.04系统网络信息存放在 /etc/network/interfaces 这个文件里，所以这里还要把下面脚本做下改动：

root@ubuntu:~/haproxy-1.8.0# vim /etc/init.d/haproxy
    # Source networking configuration.
    #. /etc/sysconfig/network # 把这句屏蔽
    
     # 增加 ubuntu16.04 支持

再次启动试试

    2月 22 09:39:43 pg-primary systemd[1]: haproxy.service: Failed with result 'exit-code'.

又报错了，提示： daemon: not found， 这个错误表示函数 daemon找不到， 在CentOS系统中的 functions脚本中有这个函数，在 ubuntu16.04中的functions脚本中没有这个函数，需要改为 start\_daemon, 修改脚本如下

root@ubuntu:~/haproxy-1.8.0# vim /etc/init.d/haproxy
    start() { 
      quiet_check
      if [ $? -ne 0 ]; then
        echo "Errors found in configuration file, check it with '$BASENAME check'."
        return 1
      fi
    
      echo -n "Starting $BASENAME: "
      # daemon $BIN -D -f $CFG -p $PIDFILE # 把这句屏蔽
      start_daemon$BIN -D -f $CFG -p $PIDFILE    # 修改为支持 ubuntu 系统的启动方式
      RETVAL=$?
      echo
      [ $RETVAL -eq 0 ] && touch $LOCKFILE
      return $RETVAL
    }

经过3次的修改，再次启动试试吧

    2月 22 09:44:20 pg-primary systemd[1]: haproxy.service: Failed with result 'exit-code'.

还是报错，你是否想放弃呢？ 我们再看看报错信息提示： /etc/init.d/haproxy: 33: \[: =: unexpected operator， 找到这一行，看是不是语法错误 ：

root@ubuntu:~/haproxy-1.8.0# cat -n /etc/init.d/haproxy | grep 33
        33	[ ${NETWORKING} = "no" ] && exit 0
       133	  status)

此处脚本中变量 $\{NETWORKING\} 没有加双引号导致，修改脚本为如下

root@ubuntu:~/haproxy-1.8.0# cat -n /etc/init.d/haproxy | grep 33
        33	[ "${NETWORKING}" = "no" ] && exit 0    # 变量加上双引号
       133	  status)

最后，我们再启动试试：

root@ubuntu:~/haproxy-1.8.0# systemctl daemon-reload
    root@ubuntu:~/haproxy-1.8.0# systemctl start haproxy
    root@ubuntu:~/haproxy-1.8.0# systemctl status haproxy

终于成功了，检查进程是否正常

root@ubuntu:~/haproxy-1.8.0# ps -ef | grep haproxy
     haproxy  43875     1  0 10:10 ?        00:00:00 /usr/sbin/haproxy -D -f /etc/haproxy/haproxy.cfg -p /var/run/haproxy.pid

检查监控状态页面访问是否正常： http://192.168.15.1:8888/haproxy-status, 这里的 haproxy-status是在配置文件里面设置的。 如果你想也可以设置用户+密码的方式访问。具体可以参考下haproxy的配置

至些， haproxy1.8.0在CentOS和Ubuntu的安装并启动成功，你是否还遇到什么问题？

### 设置自启动 ###

修改/etc/init.d/haproxy脚本，在脚本开头加入以下注释：

#!/bin/sh
    ### BEGIN INIT INFO
    # Provides: haproxy
    # Required-Start: $local_fs $network $remote_fs $syslog $named
    # Required-Stop: $local_fs $remote_fs $syslog $named
    # Default-Start: 2 3 4 5
    # Default-Stop: 0 1 6
    # Short-Description: fast and reliable load balancing reverse proxy
    # Description: This file should be used to start and stop haproxy.
    ### END INIT INFO

执行以下命令，设置自启动。

root@ubuntu:~/haproxy-1.8.0# /lib/systemd/systemd-sysv-install enable haproxy
