nginx编译安装教程

环境：

• CentOS 8
• nginx-1.19.10

安装依赖项

yum -y install gcc gcc-c++ autoconf automake make
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel

下载安装包

下载链接：
nginx: download

安装

上传到指定目录，创建nginx目录

mkdir /www/nginx
cd /www/nginx
tar -zxvf  nginx-1.19.10.tar.gz

修改文件夹的权限为root用户，为了有执行权限
chown -R root:root nginx-1.19.10

创建用户nginx：

groupadd -f www  # 创建组
useradd -g www www # 创建组以及设置用户
usermod -s /sbin/nologin nginx #修改用户默认shell /sbin/nologin

配置nginx选项

./configure --user=nginx --group=nginx --prefix=/www/nginx --with-http_stub_status_module --with-http_ssl_module --with-stream --with-http_gzip_static_module --with-http_sub_module
--user:指定运行nginx服务的用户
--group:指定运行nginx服务的组
--prefix:指定安装nginx的主目录
--with:启用模块

编译nginx

make && make install

查看目录结构

cd /www/nginx
ls
conf :配置文件目录
html:网页文件目录
logs:日志和pid进程文件
sbin:二进制启动文件
cd sbin     # 进入目录
./nginx -V  #查看编译参数
./nginx -V  #查看nginx版本

nginx进程管理

./nginx 回车进程启动
netstat -nltp 查看使用的端口
ps -aux | grep nginx 查看进程
kill 进程号，上面netstat -nltp前面的号码就是进程号

尝试访问nginx,如果你的服务器80端口是开启的，否则开启防火墙端口

http://10.10.0.212

使用systemctl管理进程

vim /usr/lib/systemd/system/nginx.service文件,相关目录替换成自己的目录。
文件示例：

/usr/lib/systemd/system 新建nginx.service文件

[Unit]
Description=nginx-The High-performance HTTP Server
After=network.target
Wants=network.target

[Service]
PIDFile=/www/nginx/logs/nginx.pid
WorkingDirectory=/www/nginx
ExecStart=/www/nginx/sbin/nginx
Restart=on-abnormal
RestartSec=5s
KillMode=mixed

StandardOutput=null
StandardError=syslog

[Install]
WantedBy=multi-user.target

重启服务
systemctl daemon-reload # 刷新缓存
systemctl start nginx # 启动进程
systemctl enable nginx # 开机启动进程

最后附上一个比较完整的nginx.conf配置文件模板
