版本区别

常用版本分为四大阵营

Nginx 的安装可以选择源码编译的方式也可以使用宝塔面板安装，本文采用的是源码编译安装。

下载 Nginx

image-20220906163814476
image-20220906163814476

使用源码编译安装

[root@hadoop100 ~] tar zxvf nginx-1.22.0.tar.gz

[root@hadoop100 ~] cd nginx-1.21.6
[root@hadoop100 ~] ./configure --prefix=/usr/local/nginx
# --prefix=/usr/local/nginx 指安装路径是/usr/local/nginx，如果前面安装了宝塔Linux面板，这一步应该不会出现环境问题。

如果出现警告或报错

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

[root@hadoop100 ~] 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

[root@hadoop100 ~] 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:

[root@hadoop100 ~] yum install -y zlib zlib-devel

出现这个代表安装成功

接下来执行

[root@centos-linux nginx-1.22.0]# make
[root@centos-linux nginx-1.22.0]# make install

启动 nginx

进入安装好的目录 /usr/local/nginx/sbin

[root@centos-linux sbin]# ./nginx         # 启动
[root@centos-linux sbin]# ./nginx -s stop     #快速停止
[root@centos-linux sbin]# ./nginx -s quit    #优雅关闭，在退出前完成已经接受的连接请求
[root@centos-linux sbin]# ./nginx -s reload    #重新加载配置

关于防火墙

关闭防火墙

[root@hadoop100 ~] systemctl stop firewalld.service

禁止防火墙开机启动

[root@hadoop100 ~] systemctl disable firewalld.service

放行端口

[root@hadoop100 ~] firewall-cmd --zone=public --add-port=80/tcp --permanent

重启防火墙

[root@hadoop100 ~] firewall-cmd --reload

安装成系统服务

创建服务脚本

[root@hadoop100 ~] 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

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

[root@hadoop100 ~] systemctl daemon-reloactdad

启动服务

[root@hadoop100 ~] systemctl start nginx.service

查看服务是否启动成功

[root@hadoop100 sbin] systemctl status nginx.service
image-20220906171209767
image-20220906171209767

开机启动

[root@hadoop100 ~] systemctl enable nginx.service
