今天真是长知识 用了 crontab 这么久 才知道原来也需要 启动
添加了定时任务 但是并不好使

[root@dev-gl-lh1 ApiAgent]# cat /etc/crontab 
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# For details see man 4 crontabs

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name command to be executed

# 缓存coin 映射数据
*/5 * * * * root /usr/bin/php /data/application/SwooleMoney/script/bin/cli.php CacheData cacheCoinMap

# 缓存交易对信息
*/1 * * * * root /usr/bin/php /data/application/SwooleMoney/script/bin/cli.php CacheData cacheSymbol

# 删除深度数据
*/1 * * * * root /usr/bin/php /data/application/SwooleMoney/script/bin/cli.php CacheData clearExchangeDepths >/tmp/clearExchangeDepths.log

每分钟执行一次脚本 但等到花都谢了 都没等到日志

# 查看crontab 状态
[root@dev-gl-lh1 ApiAgent]# /etc/init.d/crond status 
crond dead but pid file exists
# 启动crontab 服务
[root@dev-gl-lh1 ApiAgent]# /etc/init.d/crond start
Starting crond:                                            [  OK  ]

得嘞 日志有输出了 脚本成功执行, 涨知识了.
