第一節：在centos6上通過Yum安裝Nginx · Nginx指南

第一種方法：通過配置EPEL源，然后通過yum安裝Nginx服務 1、配置EPEL源，我這邊以阿里云鏡像為例（http://mirrors.aliyun.com/） [root@static ~]# cd /etc/yum.repos.d/ [root@static yum.repos.d]# ll total 24 -rw-r--r--. 1 root root 1991 Dec 1 16:16 CentOS-Base.repo -rw-r--r--. 1 root root 647 Dec 1 16:16 CentOS-Debuginfo.repo -rw-r--r--. 1 root root 289 Dec 1 16:16 CentOS-fasttrack.repo -rw-r--r--. 1 root root 630 Dec 1 16:16 CentOS-Media.repo -rw-r--r--. 1 root root 6259 Dec 1 16:16 CentOS-Vault.repo [root@static yum.repos.d]# wget -O /etc/yum.repos.d/epel-6.repo http://mirrors.aliyun.com/repo/epel-6.repo --2017-12-01 16:17:36-- http://mirrors.aliyun.com/repo/epel-6.repo Resolving mirrors.aliyun.com... 180.163.159.87, 180.163.159.88, 180.163.159.100, ... Connecting to mirrors.aliyun.com|180.163.159.87|:80... connected. HTTP request sent, awaiting response... 200 OK Length: 1083 (1.1K) [application/octet-stream] Saving to: “/etc/yum.repos.d/epel-6.repo” 100%[=====================================================================================================================================================>] 1,083 --.-K/s in 0s 2017-12-01 16:17:47 (150 MB/s) - “/etc/yum.repos.d/epel-6.repo” saved [1083/1083] （如果wget命令沒有，請通過yum安裝（yum -y install wget) [root@static yum.repos.d]# [root@static yum.repos.d]# ll epel-6.repo （查看剛剛下載的epel，目錄里是否有） -rw-r--r--. 1 root root 1083 Jul 2 2014 epel-6.repo 2、查看nginx的版本 [root@static ~]# yum info nginx ![nginx查看](https://box.kancloud.cn/3b4c3762062397ea088b10e9b63e9060_822x427.png) 3、通過Yum安裝nginx [root@static ~]# yum -y install nginx 4、通過yum安裝nginx的目錄結構配置文件： /etc/nginx 啟動腳本：/etc/rc.d/init.d/nginx 腳本配置文件：/etc/sysconfig/nginx nginx命令：/usr/sbin/nginx 模塊文件：/usr/lib64/nginx/modules 說明文檔目錄：/usr/share/doc/ 日志切割：etc/logrotate.d/nginx 日志文件：/var/log/nginx 默認主目錄：/usr/share/nginx/html/ 5、啟動Nginx服務并測試 [root@static ~]# service nginx start Starting nginx: [ OK ] [root@static ~]# ss -tunlp|grep 80 tcp LISTEN 0 128 :::80 :::* users:(("nginx",1587,7),("nginx",1589,7)) tcp LISTEN 0 128 *:80 *:* users:(("nginx",1587,6),("nginx",1589,6)) 關閉防火墻，或者放行80端口的訪問 [root@static ~]# service iptables stop [root@static ~]# iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT [root@static ~]# service iptables save iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ] 關閉Selinux服務 [root@static ~]#setenforce 0 臨時關閉 [root@static ~]# sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config [root@static ~]# cat /etc/selinux/config （重啟服務器后生效） # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted 測試訪問如下 ![nginx測試訪問（yum01）](https://box.kancloud.cn/bc5d7e144d43bc80e6fe201a84ccf4e6_1310x467.png) 第二種：通過nginx yum repository安裝最新版本的nginx 1、配置yum源 [root@static ~]# vim /etc/yum.repos.d/nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/6/$basearch/ gpgcheck=0 enabled=1 注意： baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/ Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “6” or “7”, for 6.x or 7.x versions, respectively. 2、查看nginx版本 [root@static ~]# yum info nginx ![nginxwending](https://box.kancloud.cn/c52e9cc5e7ebcdd50bbaf845830c20de_661x389.png) 3、安裝nginx [root@static ~]# yum -y install nginx 4、Nginx的目錄結構配置文件： /etc/nginx 日志文件： /var/log/nginx 默認主目錄： /usr/share/nginx/html 模塊目錄： /usr/lib64/nginx/modules 啟動腳本：/etc/rc.d/init.d/nginx 說明文檔目錄： /usr/share/doc/ 5、啟動nginx服務 [root@static nginx]# service nginx start Starting nginx: [ OK ] [root@static nginx]# ss -tunlp|grep nginx tcp LISTEN 0 128 *:80 *:* users:(("nginx",1476,6),("nginx",1478,6))
