<p>&nbsp;我主機系統(tǒng)是win7 ,vm上安裝wdlinux_lamp_32_5.6后,主機通過ssh無法登入,而且在我自己電腦上也無法打開http://ip的管理后臺,但是我在同學的電腦上可以通過SSH登入,IE 也能打開管理系統(tǒng),我們是共用一個無線路由器的,IP配的都是同一個網(wǎng)段。虛擬機centos是用橋梁方式的,靜態(tài)地址,DNS都配了,設(shè)置應(yīng)該沒有問題,就是無法ping 通我自己的主機,其他都OK的,因為在別的電腦都可以正常登陸,是不是以虛擬機網(wǎng)絡(luò)連接方式的問題啊。換了NAT貌似還是不行啊。。。<br /> 還有這個系統(tǒng)的防火墻設(shè)置在哪里啊,為什么iptables 命令是無效的。。<br /> 菜鳥,請各位大神幫忙解惑一下,感激不盡</p> http://www.fsowen.com/old/node/950#comments linux掃盲區(qū)|Linux基礎(chǔ)|Linux入門|常見問題 Fri, 02 Sep 2011 17:32:02 +0000 100fly

http://www.fsowen.com/old/node/851 <p>紅帽企業(yè)Linux第一版已經(jīng)發(fā)布近8年了。自發(fā)布之日起,該產(chǎn)品確立了作為領(lǐng)先企業(yè)級開源操作系統(tǒng)之一的地位。安裝的系統(tǒng)應(yīng)用在從便攜機到大型機 各種機器中,幫助確立了質(zhì)量、認證的基礎(chǔ)設(shè)施、長期的穩(wěn)定性、性能和安全性的標桿。從主體街到華爾街,紅帽企業(yè)Linux幾乎進入到各行各業(yè)中。</p> <p>在紅帽企業(yè)Linux進入Beta測試之時,當前支持的版本:紅帽RHEL 5,依然是紅帽軟件產(chǎn)品資產(chǎn)組合的基石。紅帽企業(yè)Linux 5是在2007年3月首次發(fā)布的,自發(fā)布后,經(jīng)歷了多次定期更新。3月份,紅帽剛剛發(fā)布了紅帽RHEL 5的第5次更新,增加了新 的特性和硬件支持。在2014年之前,紅帽RHEL 5平臺將繼續(xù)得到紅帽公司以及其ISV和OEM合作伙伴的支持。<br /> &nbsp;</p> <p>展望未來,紅帽RHEL 6模糊了虛擬、物理和云計算之間的界線,以適應(yīng)當代IT環(huán)境中發(fā)生的轉(zhuǎn)變。紅帽RHEL 6從內(nèi)核到應(yīng)用基礎(chǔ)設(shè)施到開發(fā)工具鏈都采用了升級的核心技術(shù),可以滿足未來幾代硬件、軟件技術(shù)的需要。</p> <p>新版本的主旋律包括無處不在的虛擬化、更好的穩(wěn)定性和高可用性、更高的能效以及提供多個最新軟件技術(shù)。在Beta版發(fā)布之際,將介紹幾項新的值得注 意的改進:</p> <p>全面的電源管理能力</p> <p>按時的內(nèi)核改進使系統(tǒng)可以更頻繁地將沒有活動任務(wù)的處理器變?yōu)榭臻e狀態(tài)。這將導(dǎo)致比以前版本溫度更低的CPU和更高的節(jié)電。Powertop 等新監(jiān)測工具可以幫助確定可以解決的能耗問題,從而進一步減少能耗。像&ldquo;tuned&rdquo;這樣的新調(diào)節(jié)工具(一種自適應(yīng)系統(tǒng)調(diào)節(jié)后臺程序)使系統(tǒng)可以根據(jù)服務(wù) 使用模式的分析調(diào)節(jié)能耗。</p> <p>性能改進</p> <p>紅帽工程師在我們計劃出現(xiàn)在紅帽RHEL 6中的各種內(nèi)核性能改進的上游開發(fā)中發(fā)揮著關(guān)鍵作用,完全重寫進程調(diào)度程序,使它可以通過讓更高優(yōu)先級的進程在最低限度的較低優(yōu)先級處理干擾的條件下,更 公平地在處理器之間分配計算時間。此外,還進行了多種多處理器鎖同步改進。例如,消除不必要的鎖定事件、用睡眠鎖定代替許多旋轉(zhuǎn)(spin)鎖定和采用更 高效的鎖定基元。這些根本的變化影響到許多內(nèi)核子系統(tǒng)。</p> <p>可伸縮性改進</p> <p>新推出的硬件導(dǎo)致了商品計算平臺的重大發(fā)展。例如,現(xiàn)在一臺5U機架式機柜中可容納64個CPU和2TB內(nèi)存。這些系統(tǒng)以及它們的后繼產(chǎn)品將要達到 紅帽企業(yè)Linux 5的可伸縮性極限。紅帽RHEL 6的一個主要特性是:它可以提供適應(yīng)未來系統(tǒng)的可伸縮性。其可伸縮性能力從對大量CPU和內(nèi)存配置的優(yōu)化的支持到處理更多數(shù)量的系統(tǒng)互聯(lián)總線和外設(shè)的能 力。在虛擬化變得同裸機部署一樣無處不在之時,這些能力適合于裸機環(huán)境和虛擬化環(huán)境。</p> <p>新安全特性</p> <p>一種叫做系統(tǒng)安全服務(wù)后臺程序(SSSD)的新服務(wù)提供對身份的集中管理。它還具有緩存證書供離線之用的能力。新SELinux沙箱特性使得不可信 的內(nèi)容可以在一個不會影響到系統(tǒng)其余部分的隔離的環(huán)境中執(zhí)行。這包括隔離任何運行在紅帽RHEL 6上的虛擬客戶機的能力。</p> <p>資源管理</p> <p>在一種叫做控制組(即cgroups)的新框架的幫助下,新系統(tǒng)提供對硬件資源的細顆粒度控制、分配和管理。cgroups運行在進程組水平上,可 被用于為應(yīng)用管理從CPU、內(nèi)存、網(wǎng)絡(luò)和硬盤I/O的資源。該框架還被用于管理虛擬客戶機。</p> <p>虛擬化</p> <p>紅帽RHEL 6擴展了較早的紅帽企業(yè)Linux版本提供的集成的基于KVM的虛擬化技術(shù)。新系統(tǒng)具有多個性能、調(diào)度程序和硬件支持的改進,提供無論采用什么部署模型的 更好的靈活性和控制。</p> <p>存儲</p> <p>通過FCoE和iSCSI協(xié)議對網(wǎng)絡(luò)塊存儲的支持,使利用LVM/DM執(zhí)行在線改變鏡像的和多路徑的卷大小成為可能。</p> <p>文件系統(tǒng)</p> <p>新版系統(tǒng)包括ext4文件系統(tǒng)。作為下一代擴展文件系統(tǒng)族,它包括對更大文件尺寸的支持、效率更高的硬盤空間分配、更好的文件系統(tǒng)檢查和更強健的日 志。除了ext4外,我們還打算提供XFS文件系統(tǒng)。XFS適用于超大的文件和目錄,包括像清除碎片和在文件系統(tǒng)使用時改變文件系統(tǒng)大小的能力。NFS已 經(jīng)級升到了版本4,從而包括對IPv6的支持。</p> <p>可靠性、可用性和適用性(RAS)</p> <p>新版本利用新硬件能力來提供像熱添加設(shè)備和硬件以及通過AER的PCIe設(shè)備的增強錯誤檢查等特性。它還將包括高級數(shù)據(jù)完整性特性 (DIF/DIX)。這類特性通過硬件檢查和檢驗來自應(yīng)用的數(shù)據(jù)。ABRT(自動缺陷報告工具)的引進提供了確定和報告系統(tǒng)異常情況――如內(nèi)核故障 (kernel oops)和用戶空間應(yīng)用崩潰――的更一致的方式。</p> <p>編譯器和工具</p> <p>GCC編譯器已經(jīng)升級到版本4.4。這一版本遵照C++ 0x草案標準進行編譯。它還符合OpenMP 3.0,包括許多調(diào)試功能。SystemTap改進包括對用戶空間探測的更好的支持、更安全的腳本編譯服務(wù)器和使非根用戶可以訪問SystemTap的新 的非特權(quán)模式。此外,新編譯器還有許多其它已經(jīng)升級到最新版本的庫和更多的語言和運行環(huán)境,包括完整的LAMP棧和OpenJDK。</p> <p>桌面</p> <p>新版本引進了對顯示類型的檢測和對多種顯示器的支持。我們還增加了支持NVIDIA圖形設(shè)備的升級的新驅(qū)動程序。當然,如果不對GNOME和 KDE桌面進行更新,新版本將是不完全的。</p> <p>紅帽RHEL 6中的各種技術(shù)將隨著對關(guān)鍵硬件平臺的擴展支持提供,我們認為這些技術(shù)將使新版平臺成為吸引新老客戶的誘人的選擇。同以往一樣,新版本的一部分價值在于我 們的企業(yè)認證。</p> <p>目前,成千上萬種應(yīng)用通過了在紅帽企業(yè)Linux上運行的認證,不管它運行在&ldquo;裸機&rdquo;部署、虛擬化部署,還是云部署中。這就使紅帽企業(yè) Linux成為客戶和合伙的首選操作系統(tǒng)。</p> http://www.fsowen.com/old/node/851#comments

<p>次次朋友要我推薦他們linux版本時,我都會推薦他們用Centos做服務(wù)器,Ubuntu做桌面。但朋友常常問,為什么不用Redhat,好象國內(nèi)別人都是用的這個。下面我來給解釋一下。</p> <p><span style="font-size: small"><font size="2">CentOS</font></span><span
