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
[[email protected] ~]# yum -y install gcc gcc-c++ automake autoconf libtool make
2、安装PCRE库
[[email protected] src]# cd /usr/local/src/ [[email protected] src]# wget [[email protected] pcre-8.36]# cd pcre-8.36 [[email protected] pcre-8.36]# ./configure --prefix=/usr/local/pcre [[email protected] pcre-8.36]# make [[email protected] pcre-8.36]# make install
3、安装zlib库
[[email protected] pcre-8.36]# cd /usr/local/src/ [[email protected] src]# wget [[email protected] src]# cd zlib-1.2.8 [[email protected] zlib-1.2.8]# ./configure --prefix=/usr/local/zlib [[email protected] zlib-1.2.8]# make [[email protected] zlib-1.2.8]# make install
4、安装ssl
[[email protected] zlib-1.2.8]# cd /usr/local/src/ [[email protected] src]# wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz [[email protected] src]# tar zxvf openssl-1.0.1j.tar.gz [[email protected] src]# cd openssl-1.0.1j [[email protected] openssl-1.0.1j]# ./config --prefix=/usr/local/openssl [[email protected] openssl-1.0.1j]# make [[email protected] openssl-1.0.1j]# make install
5、安装nginx
[[email protected] 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
[[email protected] 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
[[email protected] sbin]#
编译时候指定组成wwww，重新修改下即可
[[email protected] nginx]# usermod -g wwww www [[email protected] nginx]# id www uid=500(www) gid=501(wwww) groups=501(wwww) [[email protected] nginx]# cd /usr/local/nginx/sbin/ [[email protected] 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 [[email protected] 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
[[email protected] sbin]# ./nginx [[email protected] 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() [[email protected] 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) [[email protected] sbin]# kill -9 7093 [[email protected] sbin]# kill -9 10145 [[email protected] sbin]# kill -9 10146 [[email protected] sbin]# /usr/local/nginx/sbin/nginx [[email protected] sbin]# netstat -ano|grep -i ":80" tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN off (0.00/0/0) [[email protected] 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 [[email protected] 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
[[email protected] sbin]# /usr/local/nginx/sbin/nginx -s reload 或者 [[email protected] 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。
