Linux 安装Nginx

版本区别

常用版本分为四大阵营

Nginx开源版  http://nginx.org/ Nginx plus

商业版  https://www.nginx.com

openresty  http://openresty.org/cn/

Tengine     http://tengine.taobao.org

 

安装步骤

这里是开源版  nginx-1.21.6.tar.gz

1、将tar包上传到linux服务器，解压缩

2、编译安装

./configure 

./configure --prefix=/usr/local/nginx

--指定安装到/usr/local/nginx目录下

 

如果出现警告或报错

提示1:

checking for OS
+ Linux 3.10.0-693.el7.x86_64 x86_64
checking for C compiler ... not found
./configure: error: C compiler cc is not found

需要安装gcc

yum install -y gcc

 

 

 

 

 

 提示2

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

　　

 

 

 需安装perl库

yum install -y pcre pcre-devel

提示3

./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.

 

 

 需安装zlib库

yum install -y zlib zlib-devel

接下来执行 

  make               ##编译

 

 

 

 

  make install    ##安装

安装完后可以看到local目录下已经多了一个nginx目录

 

3、 启动Nginx

进入安装好的目录 /usr/local/nginx/sbin

相关启停命令
./nginx 启动
./nginx -s stop 快速停止
./nginx -s quit 优雅关闭，在退出前完成已经接受的连接请求
./nginx -s reload 重新加载配置

运行 ./nginx就已经启动了

此时在浏览器输入 ip 

 

 显示无法访问此网站

 

 

 关闭防火墙

systemctl stop firewalld.service

关于防火墙

禁止防火墙开机启动
systemctl disable firewalld.service
放行端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
重启防火墙
firewall-cmd --reload

 

刷新网页，出现Welcome to nginx！ 表示启动成功

 

创建启动nginx的便捷脚本

vi /usr/lib/systemd/system/nginx.service

 脚本内容    路径要对应安装路径

[Unit]
Description=nginx - web server
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
ExecQuit=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target

 

 使用此脚本启动nginx

查看当前nginx进程
ps -ef | grep nginx

关闭nginx
./nginx -s stop

使用上述脚本启动nginx
systemctl start nginx

查看nginx状态  图中绿色部分 Active: active (running) 则表示启动成功
systemctl status nginx

 

 开机启动

systemctl enable nginx.service

 reboot重启后 ps -ef | grep nginx   列表有nginx表示开机自启动成功
