Linux下源码监控并配置Nginx

实验环境
一台最小化安装的CentOS 7.3 虚拟机
ASP站长网安装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

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
