expect的爱恨情仇

背景

openvpn生成证书想把它做成一键化,这样添加新用户时候就方便

遇到的问题

我的代码

gg_vpn_keys.exp

#!/usr/bin/expect

set user [lindex $argv ]
set secret [lindex $argv ]

spawn /usr/share/easy-rsa/2.0/build-key-pass $user
expect {
    "phrase" {send "$secret\r";exp_continue}
    "phrase" {send "$secret\r";exp_continue}
    "CN" {send "\r";exp_continue}
    "Guangdong" {send "\r";exp_continue}
    "Shenzhen" {send "\r";exp_continue}
    "PP100" {send "\r";exp_continue}
    "Account" {send "\r";exp_continue}
    "$user" {send "\r";exp_continue}
    "EasyRSA" {send "\r";exp_continue}
    "[e-mail]" {send "\r";exp_continue}
    "password" {send "\r";exp_continue}
    "company name" {send "\r";exp_continue}
    "certificate" {send "y\r";exp_continue}
    "commit" {send "y\r";exp_continue}
    eof
}
#expect eof

exit -onexit {
    send_user "general user cert already!!!\n"
}

gg.sh

#!/bin/sh

init_env(){
    #change to root and stop openvpn and init opvpn cert
    sudo su - root
    /etc/init.d/openvpn stop
    cd /usr/share/easy-rsa/2.0 && source ./vars
}

#read opvpn username and general password
read -t 20 -p 'pls input the username:' user || exit 1
secret=`openssl rand -hex 8`

init_cert_bak_dir(){
    #create ovpn cert_bak_dir if not exist
    [ -e /server/openvpn_accout_bak ] || mkdir /server/openvpn_accout_bak
    [ -e /server/openvpn_accout_bak/$user ] && \
    exit 1 || mkdir /server/openvpn_accout_bak/$user
}

create_passfile(){
    #write cert password to user_ovpn_dir
    echo $secret > /server/openvpn_accout_bak/${user}/${user}_pass_$(date +%F).txt
    #general cert
    [ -e /server/shells/gg_vpn_keys.exp ] && \
    expect /server/shells/gg_vpn_keys.exp $user $secret
    sleep 5
    #copy cert to user_ovpn_dir
    cp /usr/share/easy-rsa/2.0/keys/${user}* /server/openvpn_accout_bak/$user
    #generay gg code
    useradd $user && chown -R ${user}.$user /server/openvpn_accout_bak/$user

    $gg=`sudo su - $user -c /usr/local/bin/gg-auth.py`
    echo $gg >> /server/openvpn_accout_bak/${user}/${user}_pass_$(date +%F).txt
    #general gg qrcode
    cd /server/openvpn_accout_bak/${user} && qrencode -o ${user}_google_qrcode.png -t png -s 20 $gg
    #general client ovpn file
    cd /server/openvpn_accout_bak/ && cp tt100.ovpn $user/${user}.ovpn
    sed -i 's#tt100#${user}#g' $user/${user}.ovpn
    #general user.tar.gz file
    cd /server/openvpn_accout_bak/ && tar zcf ${user}_openvpn.tar.gz ./$user

    echo "good lucky"
}

main(){
    init_env
    init_cert_bak_dir
    create_passfile
}

main

搞了老半天..没搞定 后面想起来在搞吧.
