18、一切都結(jié)束后，用/usr/sbin/ndc start命令啟動(dòng)bind,同樣的可用stop、restart、reload等命令參數(shù)操作 。
19、啟動(dòng)后用nslookup命令(有的系統(tǒng)推薦使用dig命令)檢驗(yàn)是否正確 。如果出現(xiàn)錯(cuò)誤，該命令將不能啟動(dòng) 。一般的錯(cuò)誤都是數(shù)據(jù)庫(kù)文件或配置文件筆誤所至 。比如少個(gè)“.”或者文件明不正確等等 。
(2) 安裝sendmail服務(wù)器
1、從www.sendmail.org下載最新的版本(這個(gè)snedmail倒是有必要升級(jí)為最新的版本，因?yàn)樗纳?jí)主要是安全漏洞問題) 。這里說明的是用的sendmail-8.12.2.tar.gz
2、cd /usr/local/src/
3、把文件下載到：/usr/local/src中
4、tar zxvf sendmail-8.12.2.tar.gz
5、cd /usr/local/src/sendmail-8.12.2
6、chmod go-w / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue
7、chown root / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue
8、cd /usr/local/src/sendmail-8.12.2/sendmail
9、sh Build
10、cd /usr/local/src/sendmail-8.12.2/cf/cf
11、建立文件sendmail.mc內(nèi)容如下，你可根據(jù)需要修改相應(yīng)部分 。
divert(-1)dnl This is the macro config file used to generate the /etc/sendmail.cfdnl file. If you modify thei file you will have to regenerate thednl /etc/sendmail.cf by running this macro config through the m4dnl preprocessor:dnl m4 /etc/sendmail.mc > /etc/sendmail.cfdnl You will need to have the Sendmail-cf pacage installed for this to work.include(`/usr/local/src/sendmail-8.12.2/cf")define(`confDEF_USER_ID",`8:12")OSTYPE(`linux")undefine(`UUCP_RELAY")undefine(`BITNET_RELAY")define(`confTO_CONNECT", `1m")define(`confTRY_NULL_MX_LIST",true)define(`confDONT_PROBE_INTERFACES",true)define(`PROCMAIL_MAILER_PATH",`/usr/bin/procmail")define(`SMART_HOST",compaq.rd.xxx.com)
