1安装PCRE库
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ 下载最新的 PCRE 源码包，使用下面命令下载编译和安装 PCRE 包：
cd /data/apps/ wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.42.tar.gz tar -zxvf pcre-8.42.tar.gz cd pcre-8.42 ./configure make make install
查看是否安装pcre
rpm -qa pcre
安装pcre
http://mirror.centos.org/centos/6/os/x86_64/Packages/pcre-7.8-7.el6.x86_64.rpm https://centos.pkgs.org/6/centos-x86_64/pcre-7.8-7.el6.x86_64.rpm.html rpm -ivh pcre-7.8-6.el6.x86_64.rpm
卸载pcre
rpm -e --nodeps pcre
2 有网络的情况下
2-2、安装编译开发工具类库
用yum安装、更新开发工具"Development Tools"和"Server Platform Deveopment"，而nginx会依赖openssl-devel和pcre-devel类库，安装如下：
[root@node2 nginx]# yum groupinstall "Development Tools" "Server Platform Deveopment"
[root@node2 ~]# yum install openssl-devel pcre-devel
2-3、创建用户和用户组
分别创建名为"nginx"的用户和组，用来运行nginx的worker进程，操作如下：
[root@node2 nginx]# groupadd -r nginx
[root@node2 nginx]# useradd -r -g nginx nginx
2-4、编译并安装
安装nginx
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
cd /data/apps wget http://nginx.org/download/nginx-1.14.1.tar.gz tar -zxvf nginx-1.14.1.tar.gz
cd nginx-1.14.1
先configure指定编译选项，如安装目录、上面创建的运行用户、需要的扩展模块（SSL、FastCGI）等，选项及参数说明：http://nginx.org/en/docs/configure.html，操作如下：
[root@node2 nginx]# ./configure \ --prefix=/usr \ --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 \ --user=nginx \ --group=nginx \ --with-http_ssl_module \ --with-http_flv_module \ --with-http_stub_status_module \ --with-http_gzip_static_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/fcgi/ \ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \ --http-scgi-temp-path=/var/tmp/nginx/scgi \ --with-pcre
Configure成功如下：
之后进行安装
make && make install
2-5、为nginx提供SysV init服务脚本
先创建/etc/init.d/nginx服务脚本，这基于ngInx自身提供的命令实现的，脚本内容如下：
vim /etc/init.d/nginx
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
options=`$nginx -V 2>&1 | grep 'configure arguments:'`
for opt in $options; do
if [ `echo $opt | grep '.*-temp-path'` ]; then
value=`echo $opt | cut -d "=" -f 2`
if [ ! -d "$value" ]; then
# echo "creating" $value
mkdir -p $value && chown -R $user $value
fi
fi
done
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
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
sleep 1
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)
$1
;;
reload)
rh_status_q || exit 7
$1
;;
force-reload)
force_reload
;;
status)
rh_status
;;
condrestart|try-restart)
rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
并为此脚本赋予执行权限，然后添加到系统服务管理列表，并让其开机自动启动，操作如下：
[root@node2 nginx]# vim /etc/init.d/nginx [root@node2 nginx]# chmod +x /etc/init.d/nginx [root@node2 nginx]# chkconfig --add nginx [root@node2 nginx]# chkconfig nginx on [root@node2 nginx]# chkconfig --list nginx
2-6、启动并访问测试
启动nginx，查看网络状态，可以看到nginx正在监听80端口；用测试主机访问nginx主机的IP，可以看到nginx的欢迎页面，过程如下：
[root@node2 nginx]# service nginx start [root@node2 nginx]# netstat -ntulp | grep nginx
如果启动之后发现报错，错误信息为
[root@XXXXXXXX nginx-1.14.1]# service nginx start
Starting nginx: /usr/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
查询 ll /usr/local/lib 看一看这个目录 如果有就关联上
如果是32位系统
[root@lee ~]# ln -s /usr/local/lib/libpcre.so.1 /lib
如果是64位系统
[root@lee ~]# ln -s /usr/local/lib/libpcre.so.1 /lib64
然后在启动nginx就OK了
service nginx start
