Linux下實現軟件的靜默安裝

靜默安裝，可以使用下面的方案：
1、用debconf-show + 包名查出預配置項
root@compute204:/var/log/keystone# debconf-show slapd

• slapd/password1: (password omitted)
  slapd/internal/adminpw: (password omitted)
  slapd/internal/generated_adminpw: (password omitted)
• slapd/password2: (password omitted)
  ...

2、在腳本里，用debconf-set-selections設置然後安裝，格式爲 {包名} {配置項key} {配置項類型} {配置項value}
cat <<LDAP_PRESEED | debconf-set-selections
slapd slapd/password1 password ${LDAP_PASS}
slapd slapd/password2 password ${LDAP_PASS}
LDAP_PRESEED

3、安裝

apt-get -y --force-yes install slapd
apt-get -y --force-yes install ldap-utils
