NGINX的下載界面會(huì)看到有三個(gè)版本
- 開發(fā)版：Mainline version
- 穩(wěn)定版：Stable version
- 歷史版：Legacy versions
注意：企業(yè)安裝NGINX需要使用穩(wěn)定版本
1. 環(huán)境準(zhǔn)備
# 查看系統(tǒng)版本
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
# 確定系統(tǒng)網(wǎng)絡(luò)環(huán)境，是否可訪問公網(wǎng)
[root@localhost ~]# ping -c 4 www.baidu.com
# 關(guān)閉防火墻
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# systemctl disable firewalld.service
[root@localhost ~]# systemctl status firewalld.service
# 修改主機(jī)名稱
[root@localhost ~]# hostnamectl set-hostname web-01
# 關(guān)閉selinux
[root@localhost ~]# sed -i.backup 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config
# 重啟系統(tǒng)
[root@localhost ~]# reboot
2. 開始安裝NGINX
2.1. 配置NGINX YUM源
[root@web-01 ~]# cat > /etc/yum.repos.d/nginx.repo << 'EOF'
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
EOF
2.2. 安裝NGINX軟件
[root@web-01 ~]# yum install -y nginx
# 查看nginx版本
[root@web-01 ~]# nginx -v
nginx version: nginx/1.18.0
2.3. 啟動(dòng)NGINX服務(wù)
# 檢查配置文件是否正確
[root@web-01 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
# 啟動(dòng)NGINX服務(wù)
[root@web-01 ~]# systemctl start nginx.service
[root@web-01 ~]# systemctl enable nginx.service
# 檢查NGINX服務(wù)運(yùn)行狀態(tài)
[root@web-01 ~]# systemctl status nginx.service
[root@web-01 ~]# ps aux|grep nginx
[root@web-01 ~]# ss -nlutp|grep 80
2.4. 訪問網(wǎng)頁測(cè)試
命令行訪問
[root@web-01 ~]# curl 127.0.0.1

3. NGINX安裝目錄
為了讓大家更加清晰的了解nginx軟件的全貌，我們有必要介紹一下NGINX安裝后整體的目錄結(jié)構(gòu)和文件功能。RPM包方式安裝使用如下命令查看
[root@web-01 ~]# rpm -ql nginx
