    -f <function> - Function name to use for jobs (can give many)
    -h <host>     - Job server host
    -H            - Print this help menu
    -v            - Print diagnostic information to stdout(false)
    -p <port>     - Job server port
    -t <timeout>  - Timeout in milliseconds
    -i <pidfile>  - Create a pidfile for the process

Client options:
    -b            - Run jobs in the background(false)
    -I            - Run jobs as high priority
    -L            - Run jobs as low priority
    -n            - Run one job per line(false)
    -N            - Same as -n, but strip off the newline(false)
    -P            - Prefix all output lines with functions names

gearman异步队列使用：

下面先做个命令行测试：

首先开两个命令行窗口：
tty1:

# gearman -w -f abc  -- wc  -m

表示统计用户输入了多少个字符。
tty2:

# gearman -f abc 'aaaa'

4
输出结果正确。

 

# gearman -f abc < /etc/php.ini  

当然也可以直接从文件中读入内容。
