实验环境
- 一台最小化安装的CentOS 7.3 虚拟机
安装nginx
安装nginx依赖包
yum install -y pcre-devel zlib-devel openssl-devel wget gcc tree vim
Nginx依赖于pcre、zlib、openssl,在编译前配置时如果有问题 可以使用yum方式安装三个包（pcre-devel、zlib-devel、openssl-devel）
从Nginx官网下载Nginx源码包
wget http://nginx.org/download/nginx-1.12.2.tar.gz
解压Nginx源码包到/root/nginx，并查看Nginx源文件结构
tar -xzvf nginx-1.12.2.tar.gz
在/root/nginx目录进行编译前配置
cd /root/nginx* ./configure --prefix=/usr/local/nginx --with-http_ssl_module
在/root/nginx目录执行编译安装
make && make install
启动nginx
关闭防火墙
setenforce 0 systemctl stop firewalld systemctl disable firewalld
进入到安装目录/usr/local/nginx，查看目录结构
cd /usr/local/nginx pwd ls
启动Nginx
/usr/local/nginx/sbin/nginx
查看Nginx进程是否启动
ps aux | grep nginx
查看Nginx占用的端口号
netstat -tlnp
使用本地主机访问虚拟机上的Nginx服务器
停止nginx
停止Nginx的三种方式
# 1. 立即停止Nginx服务 /usr/local/nginx/sbin/nginx -s stop
# 2.完成当前任务后停止 /usr/local/nginx/sbin/nginx -s quit
# 3.杀死Nginx进程 killall nginx
把nginx命令添加到环境变量
使用软连接将nginx链接到/usr/local/sbin
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin ll /usr/local/sbin/ | grep "nginx"
显示当前环境变量PATH
echo $PATH
编辑.bash_profile文件
vim ~/.bash_profile
在.bash_profile文件末尾加入以下内容
export PATH=$PATH:/usr/local/nginx/sbin
引用.bash_profile文件
source ~/.bash_profile
使用nginx命令
# 启动nginx
nginx
# 停止nginx
nginx -s quit
把nginx命令添加到系统服务
创建并编辑文件/root/service-nginx.sh
#!/bin/sh # # filename: service-nginx.sh # # nginx - this script starts and stops the nginx daemon # # chkconfig: - 85 15 # description: NGINX is an HTTP(S) server, HTTP(S) reverse # proxy and IMAP/POP3 proxy server # processname: nginx # config: /etc/nginx/nginx.conf # config: /etc/sysconfig/nginx # pidfile: /var/run/nginx.pid

force_reload() { restart }
configtest() { $nginx -t -c $NGINX_CONF_FILE }

用/root/service-nginx.sh替换/etc/init.d/nginx
mv /root/service-nginx.sh /etc/init.d/nginx
赋予可执行限权
chmod 755 /etc/init.d/nginx
执行
systemctl start nginx
源码方式安装nginx，自动化安装脚本
#!/bin/bash
# installation configuration NGINX_VERSION=1.12.2 NGINX_SRC_PATH=/root NGINX_BIN_PATH=/usr/local/nginx
# disable firewall systemctl stop firewalld setenforce 0
# installation dependence yum install -y pcre-devel zlib-devel openssl-devel wget gcc
# download nginx source package cd ${NGINX_SRC_PATH} wget http://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz
# unzip source package tar -xzvf nginx-${NGINX_VERSION}.tar.gz cd ./nginx-${NGINX_VERSION}
# install nginx ./configure --prefix=${NGINX_BIN_PATH} --with-http_ssl_module make & make install
# start nginx service cd ${NGINX_BIN_PATH}/sbin ./nginx
# END
