Nginx ("engine x") 是一个高性能的 HTTP 和 反向代理 服务器，也是一个 IMAP/POP3/SMTP 代理服务器。
nginx的模块需要第三方库的支持，检查是否安装下列库：zlib、zlib-devel（nginx扩展，gzip压缩）、openssl、openssl-devel（nginx扩展）、prce、prce-devel（重写rewrite、支持nginx伪静态）；Nginx 一般有两个版本，分别是稳定版和开发版，您可以根据您的目的来选择这两个版本的其中一个。
1、安装编译环境
[root@localhost ~]# yum -y install gcc gcc-c++ automake autoconf libtool make
2、安装PCRE库
[root@localhost src]# cd /usr/local/src/ [root@localhost src]# wget [root@localhost pcre-8.36]# cd pcre-8.36 [root@localhost pcre-8.36]# ./configure --prefix=/usr/local/pcre [root@localhost pcre-8.36]# make [root@localhost pcre-8.36]# make install
3、安装zlib库
[root@localhost pcre-8.36]# cd /usr/local/src/ [root@localhost src]# wget [root@localhost src]# cd zlib-1.2.8 [root@localhost zlib-1.2.8]# ./configure --prefix=/usr/local/zlib [root@localhost zlib-1.2.8]# make [root@localhost zlib-1.2.8]# make install
4、安装ssl
[root@localhost zlib-1.2.8]# cd /usr/local/src/ [root@localhost src]# wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz [root@localhost src]# tar zxvf openssl-1.0.1j.tar.gz [root@localhost src]# cd openssl-1.0.1j [root@localhost openssl-1.0.1j]# ./config --prefix=/usr/local/openssl [root@localhost openssl-1.0.1j]# make [root@localhost openssl-1.0.1j]# make install
5、安装nginx
[root@localhost openssl-1.0.1j]# cd ..
--with-openssl=/usr/local/src/openssl-1.0.1j --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.36指向的是源码包解压的路径，而不是安装的路径，否则会报错
检查是否安装成功
[root@localhost sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: [emerg] getgrnam("wwww") failed
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed
[root@localhost sbin]#编译时候指定组成wwww，重新修改下即可
[root@localhost nginx]# usermod -g wwww www [root@localhost nginx]# id www uid=500(www) gid=501(wwww) groups=501(wwww) [root@localhost nginx]# cd /usr/local/nginx/sbin/ [root@localhost sbin]# ./nginx -t -c /usr/local/nginx/conf/nginx.conf 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 [root@localhost sbin]#
参数"-c"指定了配置文件的路径，如果不加‘-c"参数， nginx，会默认加载其安装目录中conf子目录中的nginx.conf文件。
启动nginx
[root@localhost sbin]# ./nginx [root@localhost sbin]# /usr/local/nginx/sbin/nginx nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] still could not bind() [root@localhost sbin]# lsof -i :80 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME clock-app 7093 root 21u IPv4 53701 0t0 TCP 10.15.24.112:52763->63.238.2.211:http (ESTABLISHED) nginx 10145 root 6u IPv4 53797 0t0 TCP *:http (LISTEN) nginx 10146 www 6u IPv4 53797 0t0 TCP *:http (LISTEN) [root@localhost sbin]# kill -9 7093 [root@localhost sbin]# kill -9 10145 [root@localhost sbin]# kill -9 10146 [root@localhost sbin]# /usr/local/nginx/sbin/nginx [root@localhost sbin]# netstat -ano|grep -i ":80" tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN off (0.00/0/0) [root@localhost sbin]# ps -ef|grep "nginx" root 10167 1 0 05:17 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx www 10168 10167 0 05:17 ? 00:00:00 nginx: worker process root 10174 1882 0 05:18 pts/0 00:00:00 grep nginx [root@localhost sbin]#
执行/usr/local/nginx/sbin/nginx时提示端口被占用，因为前面我已经启动过了./nginx导致端口被占用，
重启nginx
[root@localhost sbin]# /usr/local/nginx/sbin/nginx -s reload 或者 [root@localhost sbin]# kill -HUP `cat /usr/local/nginx/logs/nginx.pid `
打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。
设置nginx开机启动
通过脚本来实现
[root@localhost ~]# vim /etc/rc.d/init.d/nginx
[root@localhost ~]# cat /etc/rc.d/init.d/nginx
