combine setp:
1、maintain server
    cd /data/git/dev_ops/wjtx_tools/ops_tools 
    python wjtx_global_tools.py -m maintain -s 1-3 

2、 close auto load in ops:

3、stop service && backup redis && backup mysql
    mysqldump --default-character-set=utf8  -uwjtx -pmMWA4DKCfeOL -h10.10.6.2 legend_241 >legend_241.sql
4、run scripts
    cd /root/opensource/migrate_server/wjtx/tools/combine_db/script
    python combine_db.py
    python combine_redis.py
    drop database
    cd /data/git/dev_ops/wjtx_tools/ops_tools  && python wjtx_tools.py  -t initdb -s 2008 
    cd /root/opensource/migrate_server/wjtx/tools/combine_db/script/out
    mysql -uroot -p0usmUwROtWjf -h10.10.6.2 legend_237 -e"source all.sql"
    cd ..
    python import_redis.py 10.10.6.59 6381 out/game_redis.script
    python import_redis.py 10.10.6.4 6379 out/global_redis.script
5、start service && change service to open && autoload
    python wjtx_global_tools.py -m open -s 1-3 
    cd /data/git/dev_ops/wjtx_tools/ops_tools  && python wjtx_tools.py  -t  autoload
