Centos上安装配置Nginx服务,并把全部文件放入/usr/My-Application/nginx文件夹中

# 创建安装目录
sudo mkdir -p /usr/My-Application
cd /usr/My-Application

# 下载 Nginx 源码包
wget http://nginx.org/download/nginx-1.24.0.tar.gz

# 解压源码包
tar -zxvf nginx-1.24.0.tar.gz
mv nginx-1.24.0 nginx
cd nginx

# 创建需要的目录

sudo mkdir -p /usr/My-Application/nginx/logs

　sudo mkdir -p /usr/My-Application/nginx/conf/conf.d

# 安装编译工具和依赖库
sudo yum install -y gcc gcc-c++ make pcre pcre-devel zlib zlib-devel openssl openssl-devel

# 如果是ubuntu系统，需要安装的编译工具和依赖库不一样
sudo apt update
sudo apt install -y wget build-essential libpcre3 libpcre3-dev zlib1g zlib1g-dev libssl-dev

# 配置编译选项，将所有路径指向 /usr/My-Application
./configure --prefix=/usr/My-Application/nginx --conf-path=/usr/My-Application/nginx/conf/nginx.conf --pid-path=/usr/My-Application/nginx/logs/nginx.pid --error-log-path=/usr/My-Application/nginx/logs/error.log --http-log-path=/usr/My-Application/nginx/logs/access.log --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module

# 编译和安装
make && sudo make install

# 创建 nginx 用户(这一步是创建系统用户，指定运行nginx服务程序的用户，需要创建，并且为此用户配置相应的权限，nginx服务才能正常运行，否则会导致报错）
sudo useradd -r -s /sbin/nologin nginx

# 设置目录权限（好像必须要设置目录权限，如果是前面创建用户，就按照这种方式来设置，如果前面不创建用户，就要通过其它方式来设置目录权限）

sudo chown -R $USER:$USER /usr/My-Application/nginx

（其它方式）

   sudo chmod -R 755 /usr/My-Application/nginx

   sudo chmod -R 700 /usr/My-Application/nginx/logs

# 创建 systemd 服务文件
sudo vim /usr/lib/systemd/system/nginx.service
