网上找了些资料，生成密码的工具不少，我就使用了其中一个。
本人使用的市centos系统，用的是epel的源，直接yum install pwgen安装这个工具
然后使用：
[[email protected] ~]# pwgen -c -n -y -H pwgen: option requires an argument -- ‘H‘ Usage: pwgen [ OPTIONS ] [ pw_length ] [ num_pw ] Options supported by pwgen: -c or --capitalize Include at least one capital letter in the password -A or --no-capitalize Don‘t include capital letters in the password -n or --numerals Include at least one number in the password -0 or --no-numerals Don‘t include numbers in the password -y or --symbols Include at least one special symbol in the password -s or --secure Generate completely random passwords -B or --ambiguous Don‘t include ambiguous characters in the password -h or --help Print a help message -H or --sha1=path/to/file[#seed] Use sha1 hash of given file as a (not so) random generator -C Print the generated passwords in columns -1 Don‘t print the generated passwords in columns -v or --no-vowels Do not use any vowels so as to avoid accidental nasty words
个人总结了下使用的参数
pwgen -c -n -y 8
c
包括1个大写字母
n
包括一个数字
y
包括一个特殊字符
8
8位密码
然后就会
[[email protected] ~]# pwgen -c -y -n 8

如果只要一个加个 -1 参数
=========================================================================
makepasswd 也是差不多的
[[email protected] ~]# makepasswd +xG=0&
[[email protected] ~]# makepasswd --help makepasswd: invalid option -- ‘-‘ Usage: makepasswd [-ceilMmnpSs] makepasswd -E [-ceilMmnSs] -c String of allowed characters (A-Za-z0-9`[email protected]#$%^&*()-_=+) -E Enumerate all possible values -e Encryption algorithm (none,base64,blowfish,des,md5,sha1,sha256,shmd5) -i Number of iterations in encryption algorithm -l Password length -M Maximum password length -m Minimum password length -n Number of passwords to generate -p Password to use -S Do not seed ourselves -s Salt to use
个人总结了下使用参数有：
[[email protected] ~]# makepasswd -l 8 -n 5 a)*@)npP k(6+LTs= Rw3Fh=FC `q$8^MDG rvz$i)vh
-l
密码长度
-n
生成密码总数
还可以加 -e 参数来生成加密密码哦。
[[email protected] ~]# makepasswd -e md5 (tqzrzpQ 5314e68d6a5c8abddc09551a7f1b3f8d
加密类型帮助上有，我就不一个一个的贴了。
