CentOS7.6.1810 安装Ngnix

系统基础环境：

# 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 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ) #1 SMP Fri Feb 1 14:54:57 UTC 2019

安装方法一：源码编译安装

基础环境 : CentOS Linux release 7.6.1810 (Core)

目录：/usr/local/src

1.1、安装前准备（根据各软件最新版本信息更改url）

下载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、安装（顺序不要错）

安装make

# yum -y install gcc automake autoconf libtool make

安装gcc编译环境

# yum install gcc-c++

安装pcre

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

安装openssl：

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

安装zlib

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

安装nginx

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

这样安装完成后，nginx的路径为/usr/local/nginx/sbin/nginx

# whereis nginx

nginx: /usr/local/nginx

安装方法二：

查看CentOS的版本

# cat /etc/redhat-release

  CentOS Linux release 7.6.1810 (Core)

添加资源库 , 在 CentOS 系统上安装 Nginx ，得先去添加一个资源库：

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

输入如下代码：

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

安装nginx

# yum -y install nginx

使用命令

# systemctl stop nginx.service  #停止nginx服务
# systemctl start nginx.service  #打开nginx服务
# systemctl restart nginx.service  #重启nginx服务
# systemctl status nginx.service  #查看nginx服务状态

开启并验证nginx安装成果：

开启nginx:

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

验证：

# curl http://localhost

应该能输出Welcome to nginx的html文件，说明安装启动成功。

 

开启外部访问

centos7默认开启了防火墙模块firewalld，可以查看一下是否开启

# 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)
 Main PID: 3618 (firewalld)
   CGroup: /system.slice/firewalld.service
           └─3618 /usr/bin/python -Es /usr/sbin/firewalld --nofork...

Mar 18 10:12:46 localhost.localdomain systemd[1]: Starting firewal...
Mar 18 10:12:46 localhost.localdomain systemd[1]: Started firewall...
Hint: Some lines were ellipsized, use -l to show in full.

或者：

# firewall-cmd --state
running

　　

关闭firewalld，然后在虚拟机外可以访问

# systemctl stop firewalld #关闭
# systemctl start firewalld #打开
# systemctl restart firewalld #重启
# systemctl disable firewalld #关闭开机启动
# systemctl enable firewalld #开机启动

 

外部访问nginx主页：http://***.***.***.***

 

添加 nginx 为系统服务,设置开机自启

1、在 /lib/systemd/system 目录添加 nginx.service 文件

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

2、写入以下内容，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、设置开机自启

# systemctl enable nginx

4、其它命令

# 启动 nginx
systemctl start nginx

# 停止
systemctl stop nginx

# 加载配置文件
systemctl reload nginx

# 重启
systemctl restart nginx

# 查看状态
systemctl status nginx
