一、一键安装四个依赖
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
二、创建一个安装目录,并下载nginx安装包
cd /usr/local
mkdir nginx #创建目录名为nginx的文件夹
cd nginx
wget http://nginx.org/download/nginx-1.13.7.tar.gz #下载nginx安装包
三、安装nginx
cd /usr/local/nginx #进入nginx目录
./configure #执行命令
如果执行下面的命令时报: -bash: ./configure: Permission denied 错误,则执行:bash ./configure
如果执行下面的命令时报: 找不到logs文件夹 错误,则在安装目录中创建 logs文件夹
make #执行make命令
make install #执行make install命令
四、检查及启动nginx
/usr/local/nginx/sbin/nginx -t #检查一下修改过的配置文件是否正确
cd /usr/local/nginx/sbin #进入安装目录
./nginx #启动nginx
如果启动没有报错,则启动成功。在浏览中输入服务器ip,如果能访问到nginx首页,则安装成功。有时可能还要关闭防火墙才能访问。
五、如果修改配置文件后要重启nginx服务
/usr/local/nginx/sbin/nginx -s reload #重启nginx
附:nginx 优化后的配置文件
