3. As a front-end Server Load balancer
========================================================== ======================

I. Preparations
# Service httpd stop
# Chkconfig httpd off
Required Software: Development Library, OpenSSL-devel

2. Deploy nginx
1. PCRE: supports regular expressions and address rewriting rewrite
# Tar zxf pcre-8.31.tar.gz
# Cd pcre-8.31
#./Configure & make install
# Ldconfig

2. nginx
# Useradd WWW
# Tar xvf nginx-1.2.2.tar.gz
# Cd nginx-1.2.2
[[Email protected] nginx-1.2.2] #./configure \
> -- User = www \
> -- Group = www \
> -- Prefix =/usr/local/nginx-1.2.2 \
-- With-http_stub_status_module \
-- With-http_sub_module \
-- With-http_ssl_module \
> -- With-PCRE =/usr/src/pcre-8.31 # PCRE source program directory

# -- With-PCRE =/usr/src/pcre-8.31 refers to the source code path of the pcre-8.31.
# -- With-zlib =/usr/src/zlib-1.2.7 refers to the source code path of the zlib-1.2.7.

# Make & make install
# Ln-S/usr/local/nginx-1.2.2 // usr/local/nginx

# Tree/usr/local/nginx/

3. Start
[[Email protected] ~] #/Usr/local/nginx/sbin/nginx
[[Email protected] ~] # Netstat-tnlp | grep: 80
TCP 0 0 0.0.0.0: 80 0.0.0.0: * Listen 10627/nginx

4. Test
# Links-dump 192.168.9.110
Welcome to nginx!
# Echo "/usr/local/nginx/sbin/nginx">/etc/rc. Local # Start the instance


Ii. Basic nginx Configuration
[[Email protected] ~] # Vim/usr/local/nginx/CONF/nginx. conf
Coremodule nginx kernel module
Eventsmodule event-driven module
Httpcoremodule HTTP kernel module

# Sed-I '/^ [\ t] * #/d;/^ [\ t] * $/D'/usr/local/nginx/CONF/nginx. conf

# Vim/usr/local/nginx/CONF/nginx. conf
Worker_processes 2; # Number of initially started processes (recommended number of CPU cores)
Worker_connections 15000; # maximum number of connections
Server {
Listen 80; # listening port
SERVER_NAME localhost; # site name
Location /{
Root HTML; # The root command specifies the Home Directory of the website (relative to the nginx installation directory)
Index index.html index.htm; # default homepage
}
Error_page 500 502 503 x.html;
Location =/50x.html {
Root HTML;
}
}

Syntax check:
#/Usr/local/nginx/sbin/nginx-T
Nginx: the configuration file/usr/local/nginx/CONF/nginx. conf syntax is OK
Nginx: configuration file/usr/local/nginx/CONF/nginx. conf test is successful


Reload nginx:
[[Email protected] ~] # Pgrep nginx
5693
5757

[[Email protected] ~] # Kill-HUP 5693
[[Email protected] ~] # Pgrep nginx
5693
5787

#/Usr/local/nginx/sbin/nginx-s reload

#/Usr/local/nginx/html/# default site home directory
# Echo "Welcome to Jeffery nginx">/usr/local/nginx/html/index.html
[[Email protected] ~] # Elinks-dump 192.168.9.110
Welcome to Jeffery nginx

========================================================== ======================

Troubleshooting:
[[Email protected] ~] #/Usr/local/nginx/sbin/nginx-T
/Usr/local/nginx/sbin/nginx: Error while loading shared libraries: libpcre. so.1: cannot
Open shared object file: no such file or directory

Compile nginx to specify -- With-PCRE =/usr/src/pcre-8.31 to specify the source code path for the pcre-8.31.
