syslog模块加载出错

[telking]

配置文件一直使用正常，从GitHub新版升级引起出错

编译参数： Tengine version: Tengine/2.2.0 (nginx/1.8.0) built by gcc 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04) TLS SNI support enabled configure arguments: --with-http_sub_module --with-http_stub_status_module --with-jemalloc --with-http_gzip_static_module --with-syslog --with-http_ssl_module --with-http_v2_module

出错日志： tarting nginx: nginx: [emerg] unknown syslog parameter "daemon:err:syslog

[lhanjian]

syslog的用法在Tengine/2.2.0应该是与官方统一了

参见http://nginx.org/en/docs/syslog.html

[telking]

使用官方的语法，nginx -t是正常，但是运行不了，出现错误提示： nginx: [alert] pipe process 1939 exited on signal 11

[cfsego]

能否把你syslog的配置贴一下。不清楚你用的是syslog还是pipe。不过不管怎么说，这块兼容性有待改进。

error_log syslog:server=192.168.1.1 debug; 就是nginx官方的测试代码

[telking]

同样的配置文件在nginx1.9.9正常使用

• reproduce with following configure:

error_log  syslog:server=192.168.1.1 debug;  # only one error_log directive in nginx.conf

• gdb stacktrace info:

hi @telking 修复了segfault段错误：https://github.com/alibaba/tengine/pull/810 你可以使用master分支最新代码测试下

Thanks to @chobits for burying my old pit.
