bt面板 宝塔面板 Python 计划任务
bt面板升级Python导致 RuntimeError: Bad magic number in .pyc file，解决了之后以为就没有问题了，后来发现设置的计划任务全都执行失败了，根据失败的错误日志判断，还是升级Python版本导致的。

解决方法
参考：bt面板升级Python导致 RuntimeError: Bad magic number in .pyc file
在解决BT面板不能启动的问题时，只将部分位置的“python”修改为“python2.6”,导致一些功能不能用。
比如“bt”文件中的
1 | ps aux |grep 'python2.6 main.pyc'|grep -v grep|awk '{print $2}' |
如果程序是通过“python2.6”启动，那么可能查询到进程ID，如果不是，那就查不到。
1、将“bt”文件中的所有“python”都修改为“python2.6”
完整文件内容如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 | #!/bin/bash# chkconfig: 2345 55 25# description: bt Cloud Service### BEGIN INIT INFO# Provides: bt# Required-Start: $all# Required-Stop: $all# Default-Start: 2 3 4 5# Default-Stop: 0 1 6# Short-Description: starts bt# Description: starts the bt### END INIT INFOpanel_path=/www/server/panelcd $panel_pathpanel_start(){ isStart=`ps aux |grep 'python2.6 main.pyc'|grep -v grep|awk '{print $2}'` if [ "$isStart" == '' ];then echo -e "Starting Bt-Panel... \c" if [ -f 'main.py' ];then python2.6 -m py_compile main.py fi nohup python2.6 main.pyc `cat data/port.pl` > /tmp/panelBoot.pl 2>&1 & sleep 0.2 isStart=`ps aux |grep 'python2.6 main.pyc'|grep -v grep|awk '{print $2}'` if [ "$isStart" == '' ];then echo -e "\033[31mfailed\033[0m" echo '------------------------------------------------------' cat /tmp/panelBoot.pl echo '------------------------------------------------------' echo -e "\033[31mError: BT-Panel service startup failed.\033[0m" return; fi echo -e "\033[32mdone\033[0m" else echo "Starting Bt-Panel...

我的系统中最初安装的是python2.6，后来又安装了python 3.7.5
执行“python -V”，得到的结果是 python 3.7.5，具体安装过程参考：CentOS release 6.10 下 Python 3.7.5 安装记录
2、修改/www/server/panel/class/crontab.py文件
在管理计划任务的时候，可以看到地址栏访问的是/crontab，于是找到/www/server/panel/class/crontab.py文件，把用到“python”的地方都修改为“python2.6”
已经创建的任务可以删除重新创建，也可以直接在线编辑脚本，将“python”都修改为“python2.6”就可以了。
