编译安装nginx-1.4.2
1、#tar xf nginx-1.4.2.tar.gz
2、#cd nginx-1.4.2
3、#./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx
执行后报：error: the HTTP rewrite module requires the PCRE library.是说明缺少pcre-devel包，
# rpm -qa |grep pcre 结果pcre-7.8-6.el6.x86_64，可见缺少pcre-devel包
查看pcre-devel是否存在：yum list pcre* ，结果如下：
Installed Packages
pcre.x86_64 7.8-6.el6 @anaconda-CentOS-201303020151.x86_64/6.4
Available Packages
pcre.i686 7.8-6.el6 base_local
pcre-devel.i686 7.8-6.el6 base_local
pcre-devel.x86_64 7.8-6.el6 base_local
pcre-static.x86_64 7.8-6.el6 base_local
可见存在。
4、#yum install pcre-devel
5、然后在执行#./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx，
执行结果显示了配置摘要：Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ md5: using system crypto library
+ sha1: using system crypto library
+ using system zlib library
nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/etc"
nginx configuration file: "/etc/nginx"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"
可见这次没报错，说明执行configure脚本成功。
6、编译#make
7、安装#make install
8、ls /usr/local/nginx,结果为：html logs sbin
ls /etc/nginx，结果为空：安装失败。因未指定主配置文件名称nginx.conf
9、卸载：rm -rf /usr/local/nginx
rm -rf /etc/nginx
10、再次在执行#./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx/nginx.conf
执行结果显示了配置摘要：Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ md5: using system crypto library
+ sha1: using system crypto library
+ using system zlib library
nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/etc/nginx"
nginx configuration file: "/etc/nginx/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"
比较一下如上次的配置摘要的区别：
nginx configuration prefix: "/etc/nginx"
nginx configuration file: "/etc/nginx/nginx.conf"
11、编译并安装：#make && make install,先实行make，成功再执行make install
12、ls /usr/local/nginx,结果为：html logs sbin
ls /etc/nginx，结果为：
fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf
fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default
13、nginx 启动：
#netstat -tnl,结果无80：
#cd /usr/local/nginx
#./nginx
#netstat -tnl,结果出现了80，说明启动成功：
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
#在浏览器中访问http://192.168.127.147/ 可能会访问不到，可能防火墙未关闭。
#service iptables stop
再次访问http://192.168.127.147/ 终于访问到了 哈哈
