Red Hat Enterprise Linux installation at 7.3 Nginx
I. Introduction
Nginx ( “engine x”) is a by Russian designer Igor Sysoev procedures developed high-performance Web server and reverse proxy, also a IMAP / POP3 / SMTP proxy server. In the case of high concurrent connections, Nginx Apache server is a good substitute.
Second, prepare
1, environment
Platform: Red Hat Enterprise Linux Server Release 7.3 (Maipo)
3.10.0-514.el7.x86_64
2, install build tools and libraries
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
3, install pcre
PCRE role is to support Ngnix Rewrite function.
Check whether the installation pcre
# pcre-config –version
bove indicate that you have installed.
If not installed, with reference to the following steps:
1) Download
https://sourceforge.net/projects/pcre/files/pcre/
2) extracting installation package:
# PCRE zxvf the tar-8.35.tar.gz
3) compile and install
# cd pcre-8.35
# ./configure
# make && make install
Third, the installation
1, download the installation package nginx
http://nginx.org/download/
2, extract
# tar zxvf nginx-1.10.2.tar.gz
3. Compile
# ./configure –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module –with-pcre
4, installation
# make
# make install
5, test
View nginx version
# /usr/local/nginx/sbin/nginx -v
Displays version information, proof has been successfully installed
Fourth, the configuration
1. Create a user
Nginx create run-use user ruready:
# / usr / sbin / groupadd ruready
# / usr / sbin / useradd -g ruready ruready
2???nginx.conf
# vi /usr/local/nginx/conf/nginx.conf
user ruready ruready;
worker_processes 2;
error_log /usr/local/nginx/logs/error.log crit; # ?????????
pid /usr/local/nginx/logs/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events {
use epoll;
worker_connections 65535;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main ‘$remote_addr – $remote_user [$time_local] “$request” ‘
‘$status $body_bytes_sent “$http_referer” ‘
‘”$http_user_agent” “$http_x_forwarded_for”‘;
access_log /usr/local/nginx/logs/access.log main;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
# server
server {
listen 80;
server_name localhost;
charset utf-8;
access_log /usr/local/nginx/logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache’s document root
# concurs with nginx’s one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
3, check the correctness of the configuration file ngnix.conf
# /usr/local/nginx/sbin/nginx -t
Fifth, start
1, the start command
# /usr/local/nginx/sbin/nginx
3, can be tested through command links
links 127.0.0.1:8080
Six commonly used commands
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/sbin/nginx/nginx.conf # ??????????
/ Usr / local / nginx / sbin / nginx -s reload # reload the configuration file
/usr/local/nginx/sbin/nginx -s reopen # ?? Nginx
/usr/local/nginx/sbin/nginx -s stop # ?? Nginx
Seven other
1, set the boot
echo “/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf” >> /etc/rc.local
2, added to the service Service
touch /etc/init.d/nginx
chmod 755 nginx // modify the script file permissions nginx
chkconfig –add nginx // The script file is added in chkconfig
chkconfig –level 35 nginx on // set nginx at startup in level 3 and 5
nginx document reads as follows:
#!/bin/sh
#
# nginx – this script starts and stops the nginx daemon
#
# chkconfig: – 85 15
