This article mainly introduces "how to install the Nginx environment on the CentOS5 server". In the daily operation, I believe many people have doubts about how to install the Nginx environment on the CentOS5 server. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to install the Nginx environment on the CentOS5 server". Next, please follow the editor to study!

I. system agreement

Software source code package location / usr/local/src

Source package compilation installation location (prefix) / usr/local/software_name

Location of scripts and maintenance programs / usr/local/sbin

MySQL database location / var/lib/mysql (can be set as appropriate)

Web site root directory / home/www/wwwroot (can be set as appropriate)

Virtual host log root / home/www/logs (can be set as appropriate)

Run the account www:www

II. Deployment and adjustment of system environment

1. Check whether the system is normal

# more / var/log/messages (check for system-level error messages)

# dmesg (check hardware devices for error messages)

# ifconfig (check whether the Nic settings are correct)

# ping www.163.com (check whether the network is working)

# cat / proc/cpuinfo (check whether the CPU frequency is normal)

# top (press 1 to check whether the number of CPU cores and memory size are normal)

2. Turn off unwanted services

# ntsysv

The following lists only the services that need to be started, and it is recommended to shut down all services that are not listed:

Atd

Crond

Irqbalance

Microcode_ctl

Network

Sendmail

Sshd

Syslog

Close SElinux: modify the SELINUX= in the / etc/selinux/config file to disabled

3. Replace the yum domestic source

# cd / etc/yum.repos.d

# mv CentOS-Base.repo CentOS-Base.repo.save

# wget http://centos.ustc.edu.cn/CentOS-Base.repo.5

# mv CentOS-Base.repo.5 CentOS-Base.repo

# yum clean all

4. Server time check and setting

# data (check whether the time is correct and whether it is China time CST)

# cp-f / usr/share/zoneinfo/Asia/Shanghai / etc/localtime (execute if the time zone is not correct, the time is skipped normally)

# yum-y install ntp (install ntp timing tool)

# chkconfig ntpd on (enable the timing service to start up)

Use yum to update the system and install the necessary software packages

# yum update-y

# yum-y install make openssl openssl-devel pcre pcre-devel libpng libpng-devel libjpeg-6b libjpeg-devel-6b freetype freetype-devel gd gd-devel zlib zlib-devel gcc gcc-c++ libXpm libXpm-devel ncurses ncurses-devel libmcrypt libmcrypt-devel libxml2 libxml2-devel imake autoconf automake screen sysstat compat-libstdc++-33 curl curl-devel
