摘要：環境準備準備服務器確保有網絡確保可用關閉規則查看規則關閉規則保險起見，再查看下查表里是否有規則有的話，也關閉關閉策略查看是否開啟關閉安裝基礎庫開始安裝訪問官網復制以下源服務器上創建的源改成驗證源從源安裝驗證顯示如下啟動

準備服務器
centos7.2

確保有網絡

ping www.baidu.com

確保yum可用

yum list | grep gcc

關閉iptables規則

# 查看iptables規則
iptables -L
# 關閉iptables規則
iptables -F
# 保險起見，再查看下查nat表里是否有規則
iptables -t nat -L
# 有的話，也關閉
iptables -t nat -F

關閉selinux策略

# 查看selinux是否開啟
getenforce
# 關閉
setenforce 0

安裝基礎庫

yum -y install gcc gcc-c++ autoconf pcre pcre-devel make automake

訪問Nginx官網
http://nginx.org/en/linux_pac...

復制以下yum源

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1

服務器上創建nginx的yum源

cd /etc/yum.repos.d
vi nginx.repo

# OS/OSRELEASE改成centos/7
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

驗證yum源

yum list | grep nginx

...
nginx.x86_64                             1:1.12.2-1.el7_4.ngx           nginx
...

從yum源安裝nginx

yum install nginx

驗證nginx

nginx -v
# 顯示如下
nginx version: nginx/1.12.2

啟動Nginx

systemctl start nginx.service

進程確認

ps -aux | grep nginx

root      9384  0.0  0.0  46296   952 ?        Ss   22:30   0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf

root      9388  0.0  0.0 112648   968 pts/0    R+   22:30   0:00 grep --color=auto nginx

訪問一下，80默認端口

初始備用目錄

cd /opt
mkdir app download logs work backup

備份Nginx配置文件

cp /etc/nginx/nginx.conf /opt/backup
cp /etc/nginx/conf.d/default.conf /opt/backup
