CentOS7.6.1810 安裝Ngnix

 

系統基礎環境：

# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)

# cat /proc/version
Linux version 3.10.0-957.5.1.el7.x86_64 ([e-mail]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ) #1 SMP Fri Feb 1 14:54:57 UTC 2019

 

安裝方法一：源碼編譯安裝

基礎環境 : CentOS Linux release 7.6.1810 (Core)

目錄：/usr/local/src

 

1.1、安裝前准備（根據各軟件最新版本信息更改url）

下載nginx、openssl、zlib、pcre

# cd /usr/local/src # wget http://nginx.org/download/nginx-1.16.0.tar.gz
# wget http://www.openssl.org/source/openssl-fips-2.0.10.tar.gz
# wget http://zlib.net/zlib-1.2.11.tar.gz
# wget https://ftp.pcre.org/pub/pcre/pcre-8.43.tar.gz

 

1.2、安裝（順序不要錯）

安裝make

# yum -y install gcc automake autoconf libtool make

 

安裝gcc編譯環境

# yum install gcc-c++

 

安裝pcre

# tar zxvf pcre-8.43.tar.gz # cd pcre-8.43 # ./configure && make && make install

 

安裝openssl：

# cd .. # tar zxvf openssl-fips-2.0.10.tar.gz # cd openssl-fips-2.0.10 # ./config && make && make install

 

安裝zlib

# cd .. # tar zxvf zlib-1.2.11.tar.gz # cd zlib-1.2.11 # ./configure && make && make install

 

安裝nginx

# cd .. # tar zxvf nginx-1.16.0.tar.gz # cd nginx-1.16.0 # ./configure && make && make install

 

這樣安裝完成后，nginx的路徑為/usr/local/nginx/sbin/nginx

# whereis nginx

nginx: /usr/local/nginx

 

安裝方法二：

查看CentOS的版本

# cat /etc/redhat-release

  CentOS Linux release 7.6.1810 (Core)

 

添加資源庫 , 在 CentOS 系統上安裝 Nginx ，得先去添加一個資源庫：

# vim /etc/yum.repos.d/nginx.repo

 

輸入如下代碼：

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

 

安裝nginx

# yum -y install nginx

 

使用命令

# systemctl stop nginx.service  #停止nginx服務
# systemctl start nginx.service  #打開nginx服務
# systemctl restart nginx.service  #重啟nginx服務
# systemctl status nginx.service  #查看nginx服務狀態

 

開啟並驗證nginx安裝成果：

開啟nginx:

# cd /usr/local/nginx/sbin # ./nginx
或
# systemctl start nginx.service

驗證：

# curl http://localhost

 

應該能輸出Welcome to nginx的html文件，說明安裝啟動成功。

 

開啟外部訪問

centos7默認開啟了防火牆模塊firewalld，可以查看一下是否開啟

# ystemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: active (running) since Mon 2019-03-18 10:12:46 EDT; 34s ago
     Docs: man:firewalld(1)

   CGroup: /system.slice/firewalld.service

Hint: Some lines were ellipsized, use -l to show in full.

或者：

# firewall-cmd --state
running

　　

關閉firewalld，然后在虛擬機外可以訪問

# systemctl stop firewalld #關閉
# systemctl start firewalld #打開
# systemctl restart firewalld #重啟
# systemctl disable firewalld #關閉開機啟動
# systemctl enable firewalld #開機啟動

添加 nginx 為系統服務,設置開機自啟

1、在 /lib/systemd/system 目錄添加 nginx.service 文件

# vim /lib/systemd/system/nginx.service

 

2、寫入以下內容，保存退出

[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s  stop
ExecRestart=/usr/local/nginx/sbin/nginx -s  restart
PrivateTmp=true
   
[Install]  
WantedBy=multi-user.target

 

3、設置開機自啟

# systemctl enable nginx

 

4、其它命令

# 啟動 nginx
systemctl start nginx

# 停止
systemctl stop nginx

# 加載配置文件
systemctl reload nginx

# 重啟
systemctl restart nginx

# 查看狀態
systemctl status nginx
