Linux-centos-7-64 bit: 5, Nginx proxy +sticky module for cookie-based load balancing

Nginx can be installed using the default packages of each platform, this article is to introduce the use of source code compilation installation, including specific compilation parameters information.

Preparatory work:

1. Install the necessary tools:

Compilation environment GCC g++ Development Library and the like need to be installed in advance.

-y install gcc gcc-c++ autoconf automake

If an error occurs during installation:

Reason:
DNS server is not configured correctly
Workaround:
①, open the file/etc/resolv.conf in which you added:

nameserver8.8.8.88.8.4.4 search localdomain

②, and then restart the network card: Use the command:service network restart

If it is in a virtual machine configuration, set the route to be the same as the host

-y install zlib zlib-devel openssl openssl-devel pcre-devel

Description

Pcre: The function used for address rewriting.

Zlib:nginx's gzip module, which transmits data packaging, saves traffic (but consumes resources).

OpenSSL: Provides SSL encryption protocol.

You can also download it online first:

Pcre:ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/

zlib:http://zlib.net/

openssl:http://www.openssl.org/source/

2. Create a new system-level user group and anonymous user, and use the following compile-time

-r-s-g-r nginx-user

View user groups and their members

groups nginx-user

Nginx Compiler installation:

1. Download nginx:http://nginx.org/en/download.html
2. Download sticky:http://download.csdn.net/detail/u014799292/9506315

Create an Nginx folder under the USR/LOCAL/SRC directory

mkdir nginx

Put the downloaded nginx-1.9.15.tar.gz into the/mnt/share resource directory and copy it to the/usr/local/src/nginx folder and unzip it and go to the extracted nginx-1.9.15 folder.
Nginx-sticky-module-1.1.tar.gz the same thing.

cp /mnt/share/nginx-1.9.15.tar.gz /usr/local/nginx/tar -zxvf nginx-1.9.15.tar.gzcd nginx-1.9.15/

./configure parameter configuration information details can be queried by help

$./configure \ #nginx启动--prefix=/usr/local/nginx \ # Sets the installation directory, which uses/usr by default/local/nginx. --sbin-path=/usr/local/nginx/nginx \ # Sets the path of the Nginx executable file, which defaults to Prefix/sbin/nginx. --conf-path=/etc/nginx/nginx.conf \ # Set the path in the nginx.conf configuration file. Nginx allows you to start with a different configuration file via the-C option on the command line. The default is prefix/conf/nginx.conf. --error-log-path=/var/log/nginx/error. log \ # Sets the name of the primary error, warning, and diagnostic file. After the installation is complete, you can change the file name at any time, using the Error_log directive in the nginx.conf configuration file. By default, the file name is Prefix/logs/error.log. --http-log-path=/var/log/nginx/access. log \ # Sets the name of the log file for the HTTP server for the primary request. After the installation is complete, you can change the file name at any time, using the Access_log directive in the nginx.conf configuration file. By default, the file name is Prefix/logs/access.log. --pid-path=/var/run/nginx.pid \ # Sets the Nginx.pid file that will store the process number of the main process. After the installation is complete, you can change the file name at any time by using the PID directive in the nginx.conf configuration file.

Nginx compile time is not the more the more the better, should be as few as possible to compile the module, not the best not to join.
The compiled nginx can be/usr/local/nginx/sbin/nginx-v to view the parameters at compile time (the specific path is more practical)

Now add the following parameters #文件夹要自己创建

./configure--add-module=/usr/local/src/nginx/nginx-  Sticky-module-1.1 \ --with-http_ssl_module--with-http_stub_status_module--sbin-path=/usr/local/nginx/nginx \--conf-path=/usr/local/nginx/nginx. conf--pid-path=/usr/local/nginx/nginx. PID--with-openssl=/usr/local/src/openssl/openssl-1.0.1s/ \

Subsequent execution

makemake install

Start Nginx, run into the/usr/local/nginx/sbin directory and see if it starts

| grep nginx

Startup success

Re-start Nginx

cd-s reload

Determine if the configuration file is correct

cd  /usr/local/nginx/sbin.-t

Shut down

Query Nginx main process number

Ps-ef | grep nginx

Calmly stop Kill-quit master process number

Fast Stop Kill-term main process number

Force Stop kill-9 Nginx

If the PID file path is configured nginx.conf, if not, in the logs directory

Kill-Signal type '/usr/local/nginx/logs/nginx.pid '

Upgrade

1. Replace the old program file with the new program first

2, KILL-USR2 the old version of the program's main process number or process file name

At this point the old Nginx master process will rename its process file to. oldbin, then execute the new version of Nginx, at which time the old and the newer versions run simultaneously

3, Kill-winch old version main process number

4. Start new/old worker process without overloading configuration

Kill-hup old/New version main process number

Calmly close the old/new process

Kill-quit old/New process number

Close old/new processes quickly

Kill-term old/New process number
