詳解apache編譯安裝httpd-2.4.54及三種風(fēng)格的init程序特點和區(qū)別
源碼包編譯實例
下面通過編譯安裝httpd來深入理解源碼包安裝(httpd-2.4.54)
下載編譯工具,httpd以及其兩個依賴包的源碼包
//源碼包建議到官方網(wǎng)站下載

init程序的三種風(fēng)格
- SysV?格:init(centos5),實現(xiàn)系統(tǒng)初始化時,隨后的初始化操作都是借助于腳本來實現(xiàn)的,(/etc/inittab)
- Upstart風(fēng)格:init(centos6),由ubuntu研發(fā)的,通過總線形式以接近于并行的方式工作,效率比SysV高,配置文件(/etc/inittab,/etc/init/*.conf)
- Systemd風(fēng)格:systemd(centos7),啟動速度快,系統(tǒng)引導(dǎo)時實現(xiàn)服務(wù)并行啟動,比前兩者的效率都高,配置文件(/usr/lib/systemd/system,/etc/systemd/system)
init程序三種風(fēng)格的特點
SysV?格特點:
- 腳本中含有大量的命令,每個命令都要啟動一個進程,命令執(zhí)行完以后就要終止這個進程。如此一來,系統(tǒng)初始化時將大量的創(chuàng)建進程,銷毀進程,工作效率會非常低
- 服務(wù)間可能會存在依賴關(guān)系,必須嚴(yán)格按照一定的順序來啟動服務(wù),前一個服務(wù)沒啟動完后面的服務(wù)就無法執(zhí)行啟動過程。不能并行進行
Upstart風(fēng)格特點:
- 基于總線方式能夠讓進程間互相通信的一個應(yīng)用程序
- 不用等服務(wù)啟動完成,只要一初始化就可以把自己的狀態(tài)返回給其他進程
Systemd風(fēng)格特點:
- 啟動速度比SysV和Upstart都快
- 不需要通過任何腳本來啟動服務(wù),systemd自身就可以啟動服務(wù),其本身就是一個強大的解釋器,啟動服務(wù)時不需要sh/bash的參與
- systemd不真正在系統(tǒng)初始化時去啟動任何一個服務(wù)只要服務(wù)沒用到,它告訴你啟動了,實際上并沒有啟動。僅當(dāng)?shù)谝淮稳ピL問時才會真正啟動服務(wù)
