nginx在CentOS中的编译安装

在安装php5.6之后，nginx莫名其妙的消失了，因此只能重装nginx了，这次我尝试用编译安装的方式来解决

准备

安装相关的依赖包

yum -y install gcc pcre pcre-devel zlib zlib-devel

下载

地址：http://nginx.org/download/nginx-1.24.0.tar.gz

wget http://nginx.org/download/nginx-1.24.0.tar.gz

编译安装

解压缩并进入目录

tar -zxvf nginx-1.24.0.tar.gz cd nginx-1.24.0

检测安装环境是否满足安装条件

./configure --prefix=/opt/base/nginx/nginx --with-openssl=/usr/local/ssl --with-http_ssl_module --with-http_stub_status_module

这里openssl是单独配置的，由于需要https的支持，增加了 --with-http_ssl_module --with-http_stub_status_module 两项配置 否则启动会报错：[emerg] the "ssl" parameter requires ngx_http_ssl_module

这一步完成后，执行make && make install 即可完成安装。

为了更好的简化操作，可以将nginx命令做成系统服务。

编写nginx 启动配置

#! /bin/bash
# chkconfig: - 85 15
PATH=/opt/base/nginx/nginx
DESC="nginx daemon"
NAME=nginx
DAEMON=$PATH/sbin/$NAME
CONFIGFILE=$PATH/conf/$NAME.conf
PIDFILE=$PATH/logs/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
set -e
[ -x "$DAEMON" ] || exit 0
do_start() {
$DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}
do_stop() {
$DAEMON -s stop || echo -n "nginx not running"
}
do_reload() {
$DAEMON -s reload || echo -n "nginx can't reload"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."
;;
reload|graceful)
echo -n "Reloading $DESC configuration..."
do_reload
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac
exit 0

保存，命名为nginx,传到/etc/init.d/目录下

修改权限

chmod a+x nginx

注册服务

chkconfig --add nginx

设置开机启动

chkconfig nginx on

相关命令

启动nginx服务

systemctl start nginx.service

停止nginx服务

systemctl stop nginx.service

重启nginx服务

systemctl restart nginx.service

重新读取nginx配置(这个最常用, 不用停止nginx服务就能使修改的配置生效)

systemctl reload nginx.service

由于我本机未配置成功，那么启动命令需要从程序所在位置进行定位启动

我这边的启动命令如下

/opt/base/nginx/nginx/sbin/nginx -c /opt/base/nginx/nginx/conf/nginx.conf

遇到的问题

nginx php 403 forbidden

908822#0: *2 FastCGI sent in stderr: "Primary script unknown" while reading response header

类似问题，解决办法，是在nginx配置的server节点下，增加index 和 root 配置项,完整配置（php）如下

server {
        listen      443 ssl;
        server_name a.test.cn;
        ssl_certificate /opt/test/cert/a.test.cn.crt;
        ssl_certificate_key /opt/test/cert/a.test.cn.key;
        ssl_session_timeout 5m;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
        ssl_prefer_server_ciphers on;
        root /opt/test/app/;
        index index.html index.php;

        location / {

                        if (!-e $request_filename){
                                rewrite  ^(.*)$  /index.php?s=$1  last;   break;
                        }
                }

                location ~ \.php$ {
                        fastcgi_pass   127.0.0.1:9000;
                        fastcgi_index  index.php;
                        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                        include        fastcgi_params;
                }

                rewrite ^/news/([0-9]+)/([0-9]+).html /show_news.php?cid=$1&id=$2 last;
                rewrite ^/news/list/([0-9]+)-([0-9]+).html /list_news.php?id=$1&pid=1 last;
                rewrite ^/news/list-([0-9]+)/([0-9]+).html /show_news.php?cid=$1&id=$2 last;
    }
