centos 8.0 安装 nginx-1.18.0 开机自启动
1、到官网下载 http://nginx.org/en/download.html
ngxin分为3个版本:
Mainline version: nginx主力版本,为开发版
Stable version: 稳定版,在生产环境中选择此版本进行安装
Legacy versions:历史版本
2、 安装依赖库
1、安装gcc环境
命令:yum install gcc-c++
2、Nginx的http模块依赖pcre
命令:yum install -y pcre pcre-devel
3、安装依赖的解压包。
命令:yum install -y zlib zlib-devel
4、ssl 功能需要 openssl 库,安装 openssl。
命令:yum install -y openssl openssl-devel
3、解压安装nginx
1、解压下载的安装包,命令:tar -zxvf nginx-1.18.0.tar.gz
2、进入nginx-1.18.0 文件夹,并创建安装目录 /usr/local/nginx ,命令: mkdir /usr/local/nginx
3、执行命令编译,命令:./configure --prefix=/usr/local/nginx 【执行安装目录/usr/local/nginx】
注意:如果要使用nginx https ,则使用以下配置
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
4、执行命令安装,命令:make & make install
5、启动nginx,并指定对应的配置文件, 使用-c指定配置文件
命令:/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
6、安装完后输入主机IP,测试是否正常:
7、针对需要修改对应的配置文件,然后重新刷新下配置即可
配置文件目录:/usr/local/nginx/conf/nginx.conf
刷新配置命令:/usr/local/nginx/sbin/nginx -s reload
4、配置开机自启动
新建shell脚本,内容如下,文件保存路径 /etc/init.d/nginx
#!/bin/sh
#
# chkconfig: 2345 10 20
#nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15

# proxy and IMAP/POP3 proxy server
