1.编译依赖 gcc 环境，如果没有 gcc 环境，需要安装 gcc
命令:yum install gcc-c++
2.nginx 的 http 模块使用 pcre 来解析正则表达式
命令:yum install -y pcre pcre-devel
3.zlib 库提供了很多种压缩和解压缩的方式， nginx 使用 zlib 对 http 包的内容进行 gzip，所以需要在 linux 上安装 zlib 库
命令:yum install -y zlib zlib-devel
4.nginx 不仅支持 http 协议，还支持 https（即在 ssl 协议上传输 http），所以需要在 linux安装 openssl 库
命令:yum install -y openssl openssl-devel
5.下载源码[目录:/usr/local/src]
命令:wget http://nginx.org/download/nginx-1.8.0.tar.gz
6.解压[目录:/usr/local/src/nginx-1.8.0]
命令:tar –zxvf nginx-1.8.0.tar.gz
7.编译[目录:/usr/local/src/nginx-1.8.0]
命令:./configure
编译成功信息:
nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/usr/local/nginx/conf"
nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"
8.安装[目录:/usr/local/src/nginx-1.8.0]
命令:make && make install
9.启动[目录:/usr/local/nginx/sbin]
命令:./nginx
备注:Nginx 的配置文件在 /usr/local/nginx/conf 目录;
启动命令:./nginx
无间断重启命令:./nginx -s reload
强制停止命令:./nginx -s stop
延迟停止命令:./nginx -s quit
10.查看进程,检测是否启动成功
命令:ps aux | grep nginx
结果:
root 1952 0.0 0.0 4356 716 pts/0 S+ 19:46 0:00 grep nginx
root 32377 0.0 0.1 5784 1260 ? Ss 19:04 0:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody 32440 0.0 0.1 6320 1656 ? S 19:20 0:00 nginx: worker process
11.防火墙开启80端口(nginx默认端口)
命令:/sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
命令:/etc/rc.d/init.d/iptables save
12.加载流程示意图
13.Nginx添加到Service
步骤一(编辑文件)
命令:vi /etc/init.d/nginx
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
# It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.confnginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
echo "nginx already running...."
exit 1
fi
echo -n $"Starting $prog: "
daemon $nginxd -c ${nginx_config}
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
echo -n $"Stopping $prog: "
killproc $nginxd
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
}
# reload nginx service functions.
reload() {
echo -n $"Reloading $prog: "
#kill -HUP `cat ${nginx_pid}`
killproc $nginxd -HUP
RETVAL=$?
echo
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
stop
start
;;
status)
status $prog
RETVAL=$?
;;
*)
echo $"Usage: $prog {start|stop|restart|reload|status|help}"
exit 1
esac
exit $RETVAL
步骤二(添加执行权限)
命令:chkconfig --add /etc/init.d/nginx
命令:chmod755/etc/init.d/nginx
命令:chkconfig --add nginx
步骤三(开机启动)
/sbin/chkconfig --level2345nginx on
步骤四(服务相关命令)
service nginx start
service nginx stop
service nginx reload
service nginx restart
