重启日志服务
service syslog restart
/opt/local/haproxy/sbin/haproxy -f /opt/local/haproxy/haproxy.cfg 启动haproxy
或者用 脚本 来做启动 重启 关闭

1.4版本以后的 启动 出现
--------------------------------------------------------------------------------------------------
[WARNING] 022/092301 (26090) : Proxy ‘www.xxx.com‘: in multi-process mode, stats will be limited to process assigned to the current request.
那是因为配置文件 nbproc > 1 所导致的...可将 配置文件 nbproc 设置为 1 或者修改编译文件..
在源码配置src/cfgparse.c找到如下行
if (nbproc > 1) {
if (curproxy->uri_auth) {
Warning("Proxy ‘%s‘: in multi-process mode, stats will be limited to process assigned to the current request.\n", curproxy->id);
if (!LIST_ISEMPTY(&curproxy->uri_auth->admin_rules)) {
Warning("Proxy ‘%s‘: stats admin will not work correctly in multi-process mode.\n", curproxy->id);
}
修改 nbproc > 1 这个数值就可以...

option httpchk HEAD /index.php HTTP/1.0 这个为监控页面..在跟目录增加index.php文件，否则报503错误.
