NGINX 的安装及平滑升级

1.安装Nginx,搭建环境

Selilnux , iptables 关掉

yum -y groupinstall "开发工具"
yum -y install gcc  gcc-c++  pcre  pcre-devel  openssl  openssl-devel

tar -zxf nginx-1.8.0.tar.gz
cd  nginx-1.8.0
useradd -s /sbin/nologin nginx
./configure  --prefix=/usr/local/nginx  --user=nginx --group=nginx --with-http_ssl_module
make && make install

ls /usr/local/nginx/

conf配置文件存放目录

html 网页目录 （/var/www//html)

logs 日志文件存放目录

sbin 存放启动nginx进程的命令

2.启动nginx进程（默认监听80端口）

/usr/local/nginx/sbin/nginx  -c  /usr/local/nginx/conf/nginx.conf
[root@squid nginx]# netstat -anptu |grep :80
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN

/usr/local/nginx/sbin/nginx -v 查看nginx版本

/usr/local/nginx/sbin/nginx -V 查看编译参数

/usr/local/nginx/sbin/nginx -t 测试默认配置文件

cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx1.conf 备份nginx的配置文件

/usr/local/nginx/sbin/nginx -s stop

终止nginx进程 的方法

kill -9 pid号

pkill -9 nginx

TERM，INT 快速关闭

QUIT 从容关闭，关闭主进程及子进程

HUP 重载配置文件

USR1 重新打开日志文件

USR2 平滑升级可执行程序

kill -HUP `cat /usr/local/nginx/logs/nginx.pid ` （重载配置文件）

/usr/local/nginx/sbin/nginx (开启nginx)

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf (开启nginx)

/usr/local/nginx/sbin/nginx -t /usr/local/nginx/conf/nginx.conf (测试nginx)

kill `cat /usr/local/nginx/logs/nginx.pid` (关闭nginx,杀死nginx进程)

/usr/local/nginx/sbin/nginx -s stop (关闭nginx)

3.平滑升级nginx软件的版本(可以在比关闭nginx服务的情况下进行平滑升级)

tar -zxf nginx-1.9.2.tar.gz
cd nginx-1.9.2
/usr/local/nginx/sbin/nginx -V
./configure --prefix=/usr/local/nginx  --user=nginx --group=nginx  --with-http_ssl_module
make
mv   /usr/local/nginx/sbin/nginx   /usr/local/nginx/sbin/oldnginx
cp objs/nginx /usr/local/nginx/sbin/
/usr/local/nginx/sbin/nginx  -v

make upgrade

/usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
sleep 1
test -f /usr/local/nginx/logs/nginx.pid.oldbin
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`

/user/local/nginx/sbin/nginx  -t
/usr/local/nginx/sbin/nginx -v

测试:

客户端查看 指定端口8080

elinks --dump http://nginx服务器的ip:8080/test.html[/code]
