Installing Nginx and Nginx tuning under Linux

Linux system for the Rhel5.6,nginx version of nginx-1.1.6.tar.gz, you can download the latest installation on the Internet, because Nginx is based on a number of modules to achieve a powerful function, so to install and compile other module packages, the module package installed here are: Agentzh-encrypt Ed-session-nginx-module-v0.02-0-gc752861.tar.gz, chunkin-nginx-module-0.23rc2.tar.gz, Google-perftools-1.8.3.tar.gz, libunwind-0.99.tar.gz, pcre-8.11.tar.gz, Simpl-ngx_devel_ Kit-v0.2.17-10-g4192ba6.tar.gz, if necessary, you can download more packages to compile and install, you can download the necessary software and documents in wiki.nginx.org. Install Nginx to start from the installation of each module package, the installation of each module package is not in order to limit, of course, before starting to install these packages to first install GCC, gcc-c++ and other tools, first ensure that the system's 80 port is not occupied and other previous work.

Operation Process:

[email protected] ~]# Yum install gcc gcc-c++ openssl-devel-y # # #准备工作

[[email protected] ~]# mkdir nginx # # #将nginx模块包放在这个目录中

Come here, Nginx installation is complete and can run normally, the following to Nginx optimization, here to nginx configuration file parameter optimization, the original configuration file of Nginx Backup to Nginx.conf_bak, the following is the optimized configuration file:

[Email protected] ~]# MV nginx_laoshi.conf/usr/local/nginx/conf/nginx.conf

[Email protected] ~]# cat/usr/local/nginx/conf/nginx.conf

}

}

Here the configuration file parameter tuning is for a machine to do, different machine parameter tuning is slightly different, should be done according to the actual situation, after tuning completed, to restart Nginx service:

[[email protected] ~]#/usr/local/nginx/sbin/nginx-s Reload # # # # #nginx服务平滑的重启, or you can also do the following to achieve the Nginx smooth restart:

[[email protected] ~]# ps-ef |grep nginx |grep master |awk ' {print $} ' # # #只查找nginx主进程号

3324

[Email protected] ~]# kill-hup 3324 # # #nginx实现了平滑重启

OK, here, Nginx compiled installation and tuning is complete.
