Linux 6下安装编译安装Nginx的步骤
前言：
Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。在高连接并发的情况下，Nginx是Apache服务器不错的替代品：Nginx在美国是做虚拟主机生意的老板们经常选择的软件平台之一。能够支持高达50,000个并发连接数的响应，而且内存开销极小。这也是Nginx广受欢迎的重要原因。本文演示了基于Linux 6下编译安装Nginx，供大家参考。
一、安装环境
# cat /etc/issue Red Hat Enterprise Linux Server release 6.3 (Santiago) Kernel \\r on an \\m # nginx -v nginx version: nginx/1.8.0
二、配置安装环境
###为简化安装及配置，此处关闭了防火墙，生产环境建议开启 # service iptables stop # chkconfig iptables off # vi /etc/selinux/config SELINUX=disabled ###创建用户及组 #groupadd -r nginx #useradd -s /sbin/nologin -g nginx -r nginx ###安装环境依赖包 http://nginx.org/en/linux_packages.html # yum install pcre-devel zlib-devel openssl openssl-devel gcc gcc-c++
三、编译及安装Nginx
# cd /tmp/
# tar -xvf nginx-1.8.0.tar.gz
# cd /nginx-1.8.0
# ./configure \\
--prefix=/etc/nginx \\
--sbin-path=/usr/sbin/nginx \\
--conf-path=/etc/nginx/nginx.conf \\
--error-log-path=/var/log/nginx/error.log \\
--http-log-path=/var/log/nginx/access.log \\
--pid-path=/var/run/nginx.pid \\
--lock-path=/var/run/nginx.lock \\
--http-client-body-temp-path=/var/cache/nginx/client_temp \\
--http-proxy-temp-path=/var/cache/nginx/proxy_temp \\
--http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp \\
--http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp \\
--http-scgi-temp-path=/var/cache/nginx/scgi_temp \\
--user=nginx \\
--group=nginx \\
--with-http_ssl_module \\
--with-http_realip_module \\
--with-http_addition_module \\
--with-http_sub_module \\
--with-http_dav_module \\
--with-http_flv_module \\
--with-http_mp4_module \\
--with-http_gunzip_module \\
--with-http_gzip_static_module \\
--with-http_random_index_module \\
--with-http_secure_link_module \\
--with-http_stub_status_module \\
--with-http_auth_request_module \\
--with-mail \\
--with-mail_ssl_module \\
--with-file-aio \\
--with-http_spdy_module \\
--with-ipv6

###如果apache httpd服务启动，建议先停止或更改端口号
# service httpd stop
# mkdir -p /var/cache/nginx/{client_temp,proxy_temp,fastcgi_temp,uwsgi_temp,scgi_temp}
# make && make install
###启动nginx
# /usr/sbin/nginx -c /etc/nginx/nginx.conf
# ps -ef|grep nginx|grep -v grep
root 33412 1 0 10:18 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx 33413 33412 0 10:18 ? 00:00:00 nginx: worker process
[root@orasrv1 cache]# netstat -nltp|grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 33412/nginx
[root@orasrv1 cache]#
四、配置nginx为系统服务
vi /etc/init.d/nginx
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \\
# proxy and IMAP/POP3 proxy server
# Author : Leshami
# Blog : http://blog.csdn.net/leshami
# processname: nginx
# pidfile: /var/run/nginx.pid
# config: /etc/nginx/nginx.conf
#path for nginx binary
nginxd=/usr/sbin/nginx
#path for nginx configuration
nginx_config=/etc/nginx/nginx.conf
#path for nginx pid
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog=nginx
# Source function library.

# Check that networking is up.
[ ${NETWORKING} = no ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
echo nginx already running....
exit 1
fi
echo -n $Starting $prog:
daemon $nginxd -c ${nginx_config}
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
echo -n $Stopping $prog:
killproc $nginxd
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
}
# reload nginx service functions.
reload() {
echo -n $Reloading $prog:
#kill -HUP `cat ${nginx_pid}`
killproc $nginxd -HUP
RETVAL=$?
echo
}
# See how we were called.

echo $Usage: $prog {start|stop|restart|reload|status|help}
exit 1
esac
exit $RETVAL
# chmod u+x /etc/init.d/nginx
# service nginx start

五、安装过程中的常见故障
./configure: error: the HTTP rewrite module requires the PCRE library. You can either disable the module by using --without-http_rewrite_module option, or install the PCRE library into the system, or build the PCRE library statically from the source with nginx by using --with-pcre=option. ./configure: error: the HTTP gzip module requires the zlib library. You can either disable the module by using --without-http_gzip_module option, or install the zlib library into the system, or build the zlib library statically from the source with nginx by using --with-zlib= option. ### 以上2个错误，请安装相应的依赖包，见本文第二部分：配置安装环境 # /usr/sbin/nginx nginx: [emerg] getpwnam(nginx) failed ### 需要创建nginx用户组及用户 # /usr/sbin/nginx nginx: [emerg] mkdir() /var/cache/nginx/client_temp failed (2: No such file or directory) ### 需要创建对应的目录
