nginx如何编译安装?

2、nginx 编译安装与配置使用(重点)

1、安装相关依赖包

安装gcc g++ pcre软件包gcc gcc-c++ pcre pcre-devel gd-devel（使nginx支持http rewrite模块）

安装openssl openssl-devel（使nginx支持ssl）

安装zlib zlib zlib-devel

yum -y install gcc gcc-c++ pcre pcre-devel gd-devel openssl openssl-devel  zlib zlib-devel

2、创建用户nginx

useradd nginx

3、安装nginx

wget http://nginx.org/download/nginx-1.16.0.tar.gz
tar xzf nginx-1.16.0.tar.gz
cd /nginx-1.16.0/
预编译
./configure \
--prefix=/usr/local/nginx \
--group=nginx \
--user=nginx \
--with-http_stub_status_module \
--with-http_v2_module \
--with-http_ssl_module \
--with-http_gzip_static_module \
--with-http_realip_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-stream \
--with-stream_ssl_module \
--with-stream_realip_module
编译安装
make && make install

4、添加环境变量

cat >/etc/profile.d/nginx.sh<<EOF
export PATH=\${PATH}:/usr/local/nginx/sbin
EOF
source /etc/profile

5、配置文件

yum安装配置文件位置：/etc/nginx/nginx.conf
源码安装配置文件位置：/usr/local/nginx/conf/nginx.conf
```
#1.nginx.conf的组成:nginx.conf一共由三部分组成，分别为：全局块、events块、http块。在http块中又包含http全局块、多个server块。每个server块中又包含server全局块以及多个location块。在统一配置块中嵌套的配置快，各个之间不存在次序关系。
备份原配置文件产生配置文件
mv /usr/local/nginx/conf/nginx.conf{,.bak}
整理配置文件如下所示：
cat >/usr/local/nginx/conf/nginx.conf<<EOF
user  nobody;
worker_processes  1;
error_log  logs/error.log;
pid        logs/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    log_format  main  '\$remote_addr - \$remote_user [\$time_local] "\$request" '
                      '\$status $body_bytes_sent "\$http_referer" '
                      '"\$http_user_agent" "\$http_x_forwarded_for"';
    access_log  logs/access.log  main;
    sendfile        on;
    tcp_nopush     on;
    keepalive_timeout  65;
    gzip  on;
    server {
        listen       80;
        server_name  localhost;
        access_log  logs/host.access.log  main;
        location / {
            root   html;
            index  index.html index.htm;
        }
  }
}
EOF

5、开机自启服务

cat >/usr/lib/systemd/system/nginx.service<<EOF
[Unit]
Description=nginx
After=network.target remote-fs.target nss-lookup.target
 
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/bin/rm -f /usr/local/nginx/logs/nginx.pid
ExecStartPost=/bin/sleep 0.1
ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
LimitNOFILE=51200
LimitNPROC=51200
LimitCORE=51200

[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable nginx

6、检测nginx配置文件

/usr/local/nginx/sbin/nginx -t

7、启动nginx服务

使用系统服务启动
systemctl start nginx
直接启动
/usr/local/nginx/sbin/nginx

8、 nginx 命令功能

nginx -c /path/nginx.conf  	     # 以特定目录下的配置文件启动nginx:
nginx -s reload            	 	 # 修改配置后重新加载生效
nginx -s stop  				 	 # 快速停止nginx
nginx -s quit  				 	 # 正常停止nginx
nginx -t    					 # 测试当前配置文件是否正确
nginx -t -c /path/to/nginx.conf  # 测试特定的nginx配置文件是否正确
#注意：
nginx -s reload 命令加载修改后的配置文件
