一、Nginx的安装

1.版本区别

• Nginx开源版
• Nginx plus 商业版
• openresty
• Tengine

2.编译安装

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

发生错误

• 提示:

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

安装gcc

yum install -y gcc

• 提示：

./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

安装perl库

yum install -y pcre pcre-devel

• 提示：

./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.

安装zlib库

yum install -y zlib zlib-devel

接下来执行

make

make install

3.启动Nginx

进入安装好的目录 /usr/local/nginx/sbin

./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

4.关于防火墙

关闭防火墙

systemctl stop firewalld.service

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

安装成系统服务

创建服务脚本

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

服务脚本内容

[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

重新加载系统服务

systemctl daemon-reload

启动服务

systemctl start nginx.service

开机启动

systemctl enable nginx.service
