CentOS 7中怎么使用cPanel配置Nginx反向代理

cPanel是当前世上功能最强大，最容易使用，最受用户欢迎的虚拟主机控制系统，很多国外主机主机都使用这套控制面板。

首先，我们需要安装 EPEL 库来启动这个进程

第一步: 安装 EPEL 库

root@server1[/usr]#yum-yinstallepel-releaseLoadedplugins:fastestmirror,tsflags,universal-hooksLoadingmirrorspeedsfromcachedhostfile*EA4:66.23.237.210*base:mirrors.linode.com*extras:mirrors.linode.com*updates:mirrors.linode.comResolvingDependencies-->Runningtransactioncheck--->Packageepel-release.noarch0:7-5willbeinstalled-->FinishedDependencyResolutionDependenciesResolved========================================================================================PackageArchVersionRepositorySize========================================================================================Installing:epel-releasenoarch7-5extras14k

第二步: 安装 nDeploy 的 CentOS RPM 库

可以安装 nDeploy 的 CentOS RPM 库来安装我们所需的 nDeploy Web 类软件和 Nginx 插件

root@server1[/usr]#yum-yinstallhttp://rpm.piserve.com/nDeploy-release-centos-1.0-1.noarch.rpmLoadedplugins:fastestmirror,tsflags,universal-hooksnDeploy-release-centos-1.0-1.noarch.rpm|1.7kB00:00:00Examining/var/tmp/yum-root-ei5tWJ/nDeploy-release-centos-1.0-1.noarch.rpm:nDeploy-release-centos-1.0-1.noarchMarking/var/tmp/yum-root-ei5tWJ/nDeploy-release-centos-1.0-1.noarch.rpmtobeinstalledResolvingDependencies-->Runningtransactioncheck--->PackagenDeploy-release-centos.noarch0:1.0-1willbeinstalled-->FinishedDependencyResolutionDependenciesResolved========================================================================================PackageArchVersionRepositorySize========================================================================================Installing:nDeploy-release-centosnoarch1.0-1/nDeploy-release-centos-1.0-1.noarch110

第三步：安装 nDeploy 和 Nginx nDeploy 插件

root@server1[/usr]#yum--enablerepo=ndeployinstallnginx-nDeploynDeployLoadedplugins:fastestmirror,tsflags,universal-hooksepel/x86_64/metalink|9.9kB00:00:00epel|4.3kB00:00:00ndeploy|2.9kB00:00:00(1/4):ndeploy/7/x86_64/primary_db|14kB00:00:00(2/4):epel/x86_64/group_gz|169kB00:00:00(3/4):epel/x86_64/primary_db|3.7MB00:00:02DependenciesResolved========================================================================================PackageArchVersionRepositorySize========================================================================================Installing:nDeploynoarch2.0-11.el7ndeploy80knginx-nDeployx86_641.8.0-34.el7ndeploy36MInstallingfordependencies:PyYAMLx86_643.10-11.el7base153klibeventx86_642.0.21-4.el7base214kmemcachedx86_641.4.15-9.el7base84kpython-inotifynoarch0.9.4-4.el7base49kpython-lxmlx86_643.2.1-4.el7base758kTransactionSummary========================================================================================Install2Packages(+5Dependentpackages)

通过以上这些步骤，我们完成了在我们的服务器上 Nginx 插件的安装。现在我们可以配置 Nginx 作为反向代理和为已有的 cPanel 用户账户创建虚拟主机，为此我们可以运行如下脚本。

第四步：启动 Nginx 作为默认的前端 Web 服务器，并创建默认的配置文件

root@server1[/usr]#/opt/nDeploy/scripts/cpanel-nDeploy-setup.shenableModifyingapachehttpandhttpsportincpanelhttpdrestartedsuccessfully.Createdsymlinkfrom/etc/systemd/system/multi-user.target.wants/nginx.serviceto/usr/lib/systemd/system/nginx.service.Createdsymlinkfrom/etc/systemd/system/multi-user.target.wants/ndeploy_watcher.serviceto/usr/lib/systemd/system/ndeploy_watcher.service.Createdsymlinkfrom/etc/systemd/system/multi-user.target.wants/ndeploy_backends.serviceto/usr/lib/systemd/system/ndeploy_backends.service.ConfGen::saheethaConfGen::satest

你可以看到这个脚本将修改 Apache 的端口从 80 到另一个端口来让 Nginx 作为前端 Web 服务器，并为现有的 cPanel 用户创建虚拟主机配置文件。一旦完成，确认 Apache 和 Nginx 的状态。

Apache 状态：

root@server1[/var/run/httpd]#systemctlstatushttpd●httpd.service-ApacheWebServerLoaded:loaded(/usr/lib/systemd/system/httpd.service;enabled;vendorpreset:disabled)Active:active(running)sinceMon2016-01-1806:34:23UTC;12sagoProcess:25606ExecStart=/usr/sbin/apachectlstart(code=exited,status=0/SUCCESS)MainPID:24760(httpd)CGroup:/system.slice/httpd.service‣24760/usr/local/apache/bin/httpd-kstartJan1806:34:23server1.centos7-test.comsystemd[1]:StartingApacheWebServer...Jan1806:34:23server1.centos7-test.comapachectl[25606]:httpd(pid24760)alreadyrunningJan1806:34:23server1.centos7-test.comsystemd[1]:StartedApacheWebServer.

Nginx 状态：

root@server1[~]#systemctlstatusnginx●nginx.service-nginx-nDeploy-highperformancewebserverLoaded:loaded(/usr/lib/systemd/system/nginx.service;enabled;vendorpreset:disabled)Active:active(running)sinceSun2016-01-1717:18:29UTC;13hagoDocs:http://nginx.org/en/docs/MainPID:3833(nginx)CGroup:/system.slice/nginx.service├─3833nginx:masterprocess/usr/sbin/nginx-c/etc/nginx/nginx.conf├─25473nginx:workerprocess├─25474nginx:workerprocess└─25475nginx:cachemanagerprocessJan1717:18:29server1.centos7-test.comsystemd[1]:Startingnginx-nDeploy-highperformancewebserver...Jan1717:18:29server1.centos7-test.comnginx[3804]:nginx:theconfigurationfile/etc/nginx/nginx.confsyntaxisokJan1717:18:29server1.centos7-test.comnginx[3804]:nginx:configurationfile/etc/nginx/nginx.conftestissuccessfulJan1717:18:29server1.centos7-test.comsystemd[1]:Startednginx-nDeploy-highperformancewebserver.

Nginx 作为前端服务器运行在 80 端口，Apache 配置被更改为监听 http 端口 9999 和 https 端口 4430。请看他们的情况：

root@server1[/usr/local/src]#netstat-plan|grephttpdtcp000.0.0.0:44300.0.0.0:*LISTEN17270/httpdtcp000.0.0.0:99990.0.0.0:*LISTEN17270/httpdtcp600:::4430:::*LISTEN17270/httpdtcp600:::9999:::*LISTEN17270/httpd

root@server1[/usr/local/src]#netstat-plan|grepnginxtcp00127.0.0.1:800.0.0.0:*LISTEN17802/nginx:mastertcp0045.79.183.73:800.0.0.0:*LISTEN17802/nginx:master

为已有用户创建的虚拟主机的配置文件在 “/etc/nginx/sites-enabled”。 这个文件路径包含了 Nginx 主要配置文件。

root@server1[/etc/nginx/sites-enabled]#ll|grep.conf-rw-r--r--1rootroot311Jan1709:02saheetha.com.conf-rw-r--r--1rootroot336Jan1709:02saheethastest.com.conf

一个域名的示例虚拟主机：

server{listen45.79.183.73:80;#CPIPVSIX:80;#ServerNamesserver_namesaheetha.comwww.saheetha.com;access_log/usr/local/apache/domlogs/saheetha.commain;access_log/usr/local/apache/domlogs/saheetha.com-bytes_logbytes_log;include/etc/nginx/sites-enabled/saheetha.com.include;}

我们可以启动浏览器查看网站来确定 Web 服务器的工作状态。安装后，请阅读服务器上的 web 服务信息。

root@server1[/home]#ipa|grep-ieth03:eth0:mtu1500qdiscpfifo_faststateUPqlen1000inet45.79.183.73/24brd45.79.183.255scopeglobaldynamiceth0root@server1[/home]#nginx-vnginxversion:nginx/1.8.0

Nginx 将会为任何最新在 cPanel 中创建的账户创建虚拟主机。通过这些简单的的步骤，我们能够在一台 CentOS 7 / cPanel 的服务器上配置 Nginx 作为反向代理。

Nginx 作为反向代理的优势

1. 便于安装和配置。
2. 效率高、性能好。
3. 防止 Ddos 攻击。
4. 支持使用 .htaccess 作为 PHP 的重写规则。
