CentOS7下 yum方式安裝Nginx的實現步驟
Nginx 是一個很強大的高性能Web和反向代理服務器，它具有眾多非常優越的特性。諸如低開銷，高并發，支持緩存，支持正反向代理，支持負載均衡，支持正則，支持rewrite等等不一而足。所以眾多粉絲們也是不計其數。本文基于CentOS 7簡要描述yum方式的安裝部署，供大家參考。

一、配置nginx yum源
演示環境[root@centos7-router ~]# more /etc/redhat-releaseCentOS Linux release 7.2.1511 (Core)[root@centos7-router ~]# vim /etc/yum.repos.d/nginx.repo[nginx]name=nginx repobaseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/gpgcheck=0enabled=1將上述配置文件中的OS替換為rhel或者centos，OSRELEASE替換為6或者7，即當前的Linux為6還是7版本查看本機ip[root@centos7-router ~]# ip addr|grep inet|grep globalinet 172.24.8.254/24 brd 172.24.8.255 scope global eno16777728inet 192.168.1.175/24 brd 192.168.1.255 scope global dynamic eno33554960
二、安裝nginx
[root@centos7-router ~]# yum install nginx -y[root@centos7-router ~]# yum install nginx-module-perl.x86_64 -y 查看生程的相關文件[root@centos7-router ~]# rpm -ql nginx/etc/logrotate.d/nginx/etc/nginx/etc/nginx/conf.d/etc/nginx/conf.d/default.conf/etc/nginx/fastcgi_params/etc/nginx/koi-utf/etc/nginx/koi-win/etc/nginx/mime.types/etc/nginx/modules/etc/nginx/nginx.conf/etc/nginx/scgi_params/etc/nginx/uwsgi_params/etc/nginx/win-utf/etc/sysconfig/nginx/etc/sysconfig/nginx-debug/usr/lib/systemd/system/nginx-debug.service/usr/lib/systemd/system/nginx.service/usr/lib64/nginx/usr/lib64/nginx/modules/usr/libexec/initscripts/legacy-actions/nginx/usr/libexec/initscripts/legacy-actions/nginx/check-reload/usr/libexec/initscripts/legacy-actions/nginx/upgrade/usr/sbin/nginx/usr/sbin/nginx-debug/usr/share/doc/nginx-1.12.2/usr/share/doc/nginx-1.12.2/COPYRIGHT/usr/share/man/man8/nginx.8.gz/usr/share/nginx/usr/share/nginx/html/usr/share/nginx/html/50x.html/usr/share/nginx/html/index.html/var/cache/nginx/var/log/nginx
三、驗證nginx
啟動nginxroot@centos7-router ~]# systemctl start nginx[root@centos7-router ~]# systemctl enable nginx ###配置自啟動[root@centos7-router ~]# ss -nltp|grep nginxLISTEN 0 128 *:80 *:* users:(("nginx",pid=65418,fd=6),("nginx",pid=65415,fd=6))查看nginx的版本[root@centos7-router ~]# nginx -vnginx version: nginx/1.12.2查看或修改配置文件[root@centos7-router ~]# more /etc/nginx/nginx.confuser nginx;worker_processes 1;error_log /var/log/nginx/error.log warn;pid /var/run/nginx.pid;events {worker_connections 1024;}http {include /etc/nginx/mime.types; ### Author : Leshamidefault_type application/octet-stream; ### Blog : http://blog.csdn.net/leshamilog_format main '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log /var/log/nginx/access.log main;sendfile on;#tcp_nopush on;keepalive_timeout 65;#gzip on;include /etc/nginx/conf.d/*.conf;}[root@centos7-router ~]# firewall-cmd --add-service=http --permanent[root@centos7-router ~]# firewall-cmd --reload從其他機器驗證nginx[root@centos7-web ~]# curl http://172.24.8.254<!DOCTYPE html><html><head><title>Welcome to nginx!</title><style>body {width: 35em;margin: 0 auto;font-family: Tahoma, Verdana, Arial, sans-serif;}</style></head><body><h1>Welcome to nginx!</h1><p>If you see this page, the nginx web server is successfully installed andworking.
