Nginx Installation

here is the continuous update fix

Nginx is a performance-oriented HTTP server that can reverse proxy http,https and mail-related (SMTP,POP3,IMAP) protocol links. It also provides load balancing and HTTP caching. Its design fully uses the asynchronous event model, reduces the cost of context scheduling, and improves the server concurrency capability. Modular design is used to provide a rich module of third-party modules.

So about Nginx, there are these tags: "async" event "modular" high performance "high concurrency" reverse proxy "load balancing"

Linux system: Centos 7 x64
Nginx version: 1.11.5 installation dependencies

Prce (redirect support) and OpenSSL (HTTPS support, if HTTPS is not required, can not be installed.) )

Yum-y Install pcre*
yum-y Install openssl*

CentOS 6.5 When I installed the "basic server", the default of these two packages are not fully installed, so the two are installed to run. Download

wget http://nginx.org/download/nginx-1.11.5.tar.gz

# if not installed wget
# Download compiled version
$ yum Install wget

Compiling the installation

Then enter the directory compile installation, configure parameter description

CD nginx-1.11.5
./configure

Installation report error such as: "C compiler cc is not found", this is the lack of a compilation environment, installation can be yum-y install gcc make gcc-c++ openssl-devel wget

If there is no error information, you can perform the installation below:

Make make
Install

nginx Test

Two results will appear when you run the following command

./nginx-t

# nginx:the configuration file/usr/local/nginx/conf/nginx.conf syntax is OK
# nginx:configuration fi Le/usr/local/nginx/conf/nginx.conf Test is successful

Edit the vi/lib/systemd/system/nginx.service file without creating a touch nginx.service and then modify the following according to the specific circumstances Add to Nginx.service file:

[Unit]
description=nginx1.11.5
after=network.target remote-fs.target nss-lookup.target

[Service]

Type= Forking
pidfile=/var/run/nginx.pid
execstartpre=/usr/local/nginx/sbin/nginx-t-c/usr/local/nginx/conf/ nginx.conf
execstart=/usr/local/nginx/sbin/nginx-c/usr/local/nginx/conf/nginx.conf
ExecReload=/bin/ Kill-s HUP $MAINPID
execstop=/bin/kill-s QUIT $MAINPID
privatetmp=true

[Install]
wantedby= Multi-user.target

Set the boot up to make the configuration effective:

Systemctl Enable Nginx.service

# Shut down process

# smooth off nginx
/usr/local/nginx/sbin/nginx-s quit

# View the installation status of Nginx

turn off the firewall or add firewall rules to test the

Service Iptables Stop

or edit the configuration file:

Vi/etc/sysconfig/iptables

Save after adding such an open 80-port rule:

-A input-m state--state new-m tcp-p TCP--dport 80-j ACCEPT

Restart the service:

Service Iptables Restart

Restart Service Firewall error Resolution

Service iptables Restart
# redirecting To/bin/systemctl restart Iptables.service # Failed to
restart Iptables.service:Unit Iptables.service failed to load:no such file or directory.

Firewalls are managed by Firewalld in CentOS 7 or Rhel 7 or Fedora, and of course you can restore the traditional management style. or use the new command for management.
If you use tradition, please execute the order:

# Traditional Command
systemctl stop firewalld
systemctl mask Firewalld

# installation Command
yum install iptables-services

systemctl enable iptables 
service iptables restart
