Install nginx on linux

---------Installation
First install dependencies
yum -y install openssl openssl-devel
yum -y install pcre-devel
Download nginx
wget http://nginx.org/download/nginx-1.10. 0.tar.gz
Installation
Unzip first
tar -zxvf nginx-1.10.0.tar.gz
Then compile
cd nginx-1.10.0
./configure --prefix=/usr/local/nginx
make
make install
Start
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
Stop
Check the process number first
ps -ef |grep nginx
root 12901 1 0 11: 26? 00:00:00 nginx: master proces ./nginx
nobody 12902 12901 0 11:26? 00:00 nginx: worker process
Stop calmly: Kill -S Quit 12901
Quick stop: kill - s TERM 12901/ kill -s INT 12901
Force stop: killall nginx
Restart
Verify whether the configuration file is correct,
Method 1: You must enter /usr/local/nginx/sbin/ to execute./nginx -t
Method 2: / usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
Start restart
Method 1: You must enter /usr/local/nginx/sbin/ to execute ./nginx -s reload
Method 2: kill -HUP master title
Build nginx+tomcat environment
Add the following configuration in the nginx configuration file (simple example)
nginx is installed in the directory: /usr/local/nginx/
user nobody;
worker_processes 1;
events {
worker_connections 1024;
}

---------Load balancing strategy
1, none Polling method (one at a time round), the default is
2. You can change the polling by weight (default is 1). The higher the weight value, the more requests are allocated
3. ip_hash performs hash operation according to the user's ip address to obtain the hash value, bind On a certain server, 续 The IP of the subsequent users will be locked on a certain server. At this time, the weight will fail.
4 and FAIR are third -party. According to their own algorithms, the load of the server is obtained.
5. url_hash third-party, performs hash operation based on the requested URL to bind the server
Install the third-party module
1. Download gnosek-nginx-upstream-fair-a18b409.tar.gz
2. Unzip tar -zxvf gnosek -nginx-upstream-fair-a18b409.tar.gz
3. Configure, enter the nginx decompression directory
./configure --prefix=/usr/local/nginx --add-module=/picclife/soft/nginx-upstream -fair
4. Compile, do not install, because we installed nginx before
make
5. Enter the objs directory
[root@zhanglw-5 objs]# ls
addon autoconf.err Makefile nginx nginx.8 ngx_auto_config.h ngx_auto_headers. h ngx_modules.c ngx_modules.o src
6. Replace nginx. Previously, our nginx was installed in the /usr/local/nginx directory
cp nginx /usr/local/nginx/sbin/

Stop nginx before replacing. Otherwise it cannot be replaced

The above has introduced the installation of nginx on Linux, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
