三、安装配置nginx 官网www.nginx.org
(1)解决依赖安装 yum -y install gcc gcc+ gcc-c++ gd zlib zlib-devel openssl openssl-devel autoconf automake
创建nginx运行所需要的用户
[root@nginx ~]# groupadd -r -g 108 nginx
[root@nginx ~]# useradd -r -u 108 -g 108 nginx -s /sbin/nologin
（2）安装pcre
[root@nginx ~]#tar -jxf pcre-8.36.tar.bz2
[root@nginx ~]#cd pcre-8.36
[root@nginx ~]# ./configure
[root@nginx ~]#make && make install
(3)安装nginx
[root@nginx ~]# tar -zxvf nginx-1.9.0.tar.gz
[root@nginx ~]# cd nginx-1.9.0
[root@nginx ~]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --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/nginx.pid --lock-path=/var/lock/nginx.lock --with-http_ssl_module --http-client-body-temp-path=/var/tmp/nginx/client --http-proxy-temp path=/var/tmp/nginx/proxy --http-fastcgi-temp-path=/var/tmp/nginx/fcsi --with-pcre --with-http_flv_module --with-http_gzip_static_module
[root@nginx ~]# make && make install
(4)启动nginx：
#/usr/sbin/nginx
nginx: [emerg] getpwnam("nginx") failed
提示需要创建nginx用户和组：
再次运行就好了，如果出现下面错误，手工创建相应目录就好：
nginx: [emerg] mkdir() "/var/tmp/nginx/client/" failed (2: No such file or directory)
[root@nginx-backup /]# mkdir -p /var/tmp/nginx/client
[root@nginx-backup init.d]# ln -s /lib/libpcre.so.0.0.1 /lib/libpcre.so.1
(5)自己开发，添加nginx启动脚本
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /usr/local/nginx/logs/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
lockfile=/var/lock/subsys/nginx
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0
$1

stop)
rh_status_q || exit 0
$1
;;
restart|configtest)

rh_status_q || exit 7

echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
(6)/usr/local/sbin/nginx -c /usr/local/nginx/conf/nginx.conf 启动nginx -c指定配置文件路径
(7)[root@nginx-master ~]# ps -ef | grep nginx 通过ps查找nginx主进程号master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
(8)查看启动状态，端口监听一般就成功
[root@nginx ~]# netstat -tulnp | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 3373/nginx
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 3373/nginx
tcp 0 0 0.0.0.0:8081 0.0.0.0:* LISTEN 3373/nginx
[root@nginx ~]# ps -ef | grep nginx
root 3373 1 0 10:03 ? 00:00:00 nginx: master process /usr/sbin/nginx
nginx 3374 3373 0 10:03 ? 00:00:00 nginx: worker process
nginx 3375 3373 0 10:03 ? 00:00:00 nginx: worker process
nginx 3376 3373 0 10:03 ? 00:00:00 nginx: worker process
nginx 3377 3373 0 10:03 ? 00:00:00 nginx: worker process
nginx 3378 3373 0 10:03 ? 00:00:00 nginx: worker process
nginx 3379 3373 0 10:03 ? 00:00:00 nginx: worker process
root 3446 2515 0 10:03 pts/0 00:00:00 grep nginx
[root@nginx ~]#
(9)打开浏览器访问：http://你的ip+端口/ 默认是80
出现下面消息，配置成功。
