deploy high performance web server – nginx
1、install basic independent packages
yum -y install gcc openssl-devel pcre-devel zlib-devel
2、deploy nginx
useradd nginx -s /sbin/nologin #add nginx user
tar zxvf nginx-1.2.7.tar.gz #uncompress nginx tar.gz package.
cd nginx-1.2.7
./configure \
–user=nginx \ # user is nginx
–group=nginx \ #user group is nginx
–prefix=/usr/local/nginx/ \ # nginx home path
–with-http_stub_status_module \
–with-http_ssl_module #ssl module
# for more parameter,you can refoer to this command
./configure –help
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”
make & make install
check whether the configuration in nginx is correct or not
after installation.
/usr/local/nginx/sbin/nginx –v
3、configure nginx
cd /usr/local/nginx/conf/
rm -rf nginx.conf
vim nginx.conf
paste the following configuration to nginx.conf
user nginx nginx; #user and user group
worker_processes 8; #process amount when nginx start
error_log logs/nginx_error.log crit; #error log and log level
pid /usr/local/nginx/nginx.pid; #PID file path
worker_rlimit_nofile 51200;
events
{
use epoll; # epoll module
worker_connections 51200; #maximum allowed connection of each process.
}

}
}
save and exit！
NOTE : this is a baisc confifguration file，you need to edit it again if you would like to
configure other featuer.
4、start nginx，and check the working status
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ps -ef | grep nginx
netstat -nltp | grep 80
links 127.0.0.1 # if “welcome to nginx！” appeared, this indicat nginx startup successfully
or you can input “localhost” in url bar of web brower , if you have seen “welcome to nginx!”
It means that nginx starup successfully
