linux安装nginx(centos8.2)

一、环境安装

        yum install gcc-c++

        yum install -y pcre pcre-devel

        yum install -y zlib zlib-devel

        yum install -y openssl openssl-devel

        iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

        iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 443 -j ACCEPT

        iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT

        iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 21 -j ACCEPT

        iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 30000:30999 -j ACCEPT

二、下载nginx

        wget -c https://nginx.org/download/nginx-1.20.2.tar.gz

        2.1、解压nginx

                tar -zxvf nginx-1.20.2.tar.gz

        2.2、到nginx目录下

                cd nginx-1.20.2/

        2.3、配置

                ./configure --prefix=/usr/local/nginx --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_gzip_static_module --http-client-body-temp-path=/var/temp/nginx/client --http-proxy-temp-path=/var/temp/nginx/proxy --http-fastcgi-temp-path=/var/temp/nginx/fastcgi --http-uwsgi-temp-path=/var/temp/nginx/uwsgi --http-scgi-temp-path=/var/temp/nginx/scgi

                如果版本太低会报错

                解决方法：make

        2.4、安装

                make install

        2.5、启动

                cd /usr/local/nginx/sbin

                ./nginx

                如果报错：出现这种问题的解决方法 nginx: [emerg] mkdir() "/var/temp/nginx/client" failed (2: No such file or directory)

                解决方法：sudo mkdir -p /var/temp/nginx

        2.6、关闭

                ./nginx -s stop

                启动报错解决：

                        [root@VM-24-17-centos sbin]# ./nginx nginx:

                        [emerg] open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)

                        [root@VM-24-17-centos sbin]# mkdir -p /var/run/nginx
