Nginx Cache Purge Module For fastcgi_cache : Building Nginx From Source
There are two modules so far we noticed :
|
1 2 |
https://github.com/FRiCKLE/ngx_cache_purge https://github.com/wandenberg/nginx-selective-cache-purge-module |
Now the commands :
|
1 2 3 4 |
# debian, Linux Mint, ubuntu sudo apt-get install build-essential zlib1g-dev libpcre3-dev libssl-dev libxslt1-dev libxml2-dev libgd2-xpm-dev libgeoip-dev libgoogle-perftools-dev libperl-dev -y # REHL, centos... sudo yum install gcc-c++ pcre-devel zlib-devel make wget openssl-devel libxml2-devel libxslt-devel gd-devel perl-ExtUtils-Embed GeoIP-devel gperftools-devel -y |
Browse on the browser here – http://nginx.org/download/ for the latest version & replace the version number :
|
1 2 3 4 5 6 7 8 9 |
cd ~ wget http://nginx.org/download/nginx-1.9.0.tar.gz tar -xzf nginx-1.9.0.tar.gz wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz tar -xzf ngx_cache_purge-2.3.tar.gz cd nginx-1.9.0.tar.gz ./configure --help # see help page above ./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_ssl_module --with-http_spdy_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_geoip_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_stub_status_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-pcre --with-google_perftools_module --with-debug --add-module=../nginx-cache-purge-module |
If you use the second module, then you should wget a tagged release and configure it. You must follow that Github description and install Redis 2.8 / newer, hiredis, redis_nginx_adapter library before configuring :
|
1 2 3 4 5 6 7 8 |
cd ~ wget http://nginx.org/download/nginx-1.9.0.tar.gz tar -xzf nginx-1.9.0.tar.gz wget https://github.com/wandenberg/nginx-selective-cache-purge-module/archive/0.5.5.tar.gz tar -xzf 0.5.5.tar.gz cd nginx-1.9.0.tar.gz ./configure --help # see the options ./configure --with-ld-opt='-L/usr/lib/' --with-cc-opt='-I/usr/include/hiredis/' --prefix=/usr/local/nginx --sbin-path=/usr/local/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_ssl_module --with-http_spdy_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_geoip_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_stub_status_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-pcre --with-google_perftools_module --with-debug --add-module=../0.5.5 |
Now you can run :
---
|
1 2 |
make make install |
Wait till the process completes and run sudo service nginx start or sudo systemctl start nginx. Run nginx -V to test.
