显示任务执行信息，去掉过程和错误信息

rex -qw uptime

把执行结果存到文件中

rex -qw uptime | tee -a info.log

指定主机执行

rex -qw -H ‘192.168.1.1 192.168.1.2’ uptime

显示主机ip的

my $output = run “uptime”;
say connection->server.$output;

多进程

parallelism n;

sudo执行：
sudo TRUE;
sudo_password ‘ttrttr’;

指定分组执行 temp：

rex -qw -G temp $task

列出命令项目 rex -h

列出任务和分组列表 rex -T

通过文件执行定义任务

rex -qw creatuser -f usermange

任务sample

添加sudo
task “addsudo”,group =>”all”, sub {
append_if_no_such_line “/etc/sudoers”, “yy ALL=(ALL) ALL”;
say connection->server.” Sudo add success!”;
};

删除用户

task “addsudo”,group =>”all”, sub {
append_if_no_such_line “/etc/sudoers”, “yy ALL=(ALL) ALL”;
say connection->server.” Sudo add success!”;
};

创建或者修改用户

task “create-user”,group => “all”, sub {

say connection->server.” begin create”;

create_user “yy”,
password => ‘yy123’;
create_user “xx”,
password => ‘xx123’;

say connection->server.” done!”;
};

启用ini文件定义分组:
—————-

use Rex -base;
use Rex::Group::Lookup::INI;
use Rex::Commands::User;
user “yy”;

password ‘ttrttr’;

pass_auth;

port 65522;

groups_file “list.ini”;

parallelism 10;

ini文件

list.ini

[all]

192.168.1.1
192.168.1.2
..

服务列表

task “list”, group => “all”, sub {
