centos 6.x进程守护者supervisor

1,下载安装

supervisor-3.2.0.tar.gz下载 https://pan.baidu.com/s/1kVbpHqv

tar zxf supervisor-3.2.0.tar.gz
cd supervisor-3.2.0
python setup.py install

测试安装是否成功：echo_supervisord_conf

如果报类似这样的错：

No local packages or download links found for meld3>=0.6.5
error: Could not find suitable distribution for Requirement.parse('meld3>=0.6.5')

解决：

下载meld3部署包：wget https://pypi.python.org/packages/source/m/meld3/meld3-1.0.2.tar.gz
解压：tar -xvf meld3-1.0.2.tar.gz
进入解压包：cd meld3-1.0.1.tar.gz
开始安装：python setup.py install

创建默认的配置文件，为nginx创建进程守护案例：

echo_supervisord_conf >/etc/supervisord.conf
vi /etc/supervisord.conf

; Sample supervisor config file.

解决：wordpress出现“此页面包含重定向循环”的问题

这两个文件均位于wp_includes文件夹下。首先，对于canonical.php文件的修改，利用文本编辑器打开该文件，开头注释下面就可以找到如下语句：

1,

function redirect_canonical( $requested_url = null, $do_redirect = true ) {
把true修改为false即可。

2,
其次，对于template-loader.php文件，打开之后找到如下代码片段：
if ( defined(‘WP_USE_THEMES’) && WP_USE_THEMES )do_action(‘template_redirect’);
把这段代码删除或者用PHP的注释符号注释掉即可，你可以用“”多行注释来注释掉此段代码。

推荐：koa2与mongodb交互

如果是使用mongodb与node.js配合使用，这推荐安装monk模块，不管是koa 2还是express 4.x都推荐使用。

详细文档：https://automattic.github.io/monk/docs/GETTING_STARTED.html

安装：

npm install --save monk

调用：

const monk = require('monk');
const url = 'localhost:27017/xgllseo';
const db = monk(url);

创建唯一索引自动递增：

先执行创建一个集合专门用来存储自增数字

db.createCollection("counters")
db.counters.insert({_id:"productid",sequence_value:1})

批量插入数据的同时，递增索引

const collection = db.get('admin'); //admin是集合，根据需求修改成自己的集合
db.get('counters').find({}).then((docs) => {  //1，先查询当前最新的自增数值是多少
   var _id=docs[0].sequence_value;
   function autoadd() {
      return ++_id;   //2，当前最新的自增数，每次都累加1
   }
   collection.insert([
     {"_id":autoadd(),user: ctx.request.body.user,pass: ctx.request.body.pass},  //3，每插入一条数据，索引就累加1了
     {"_id":autoadd(),user:'a123',pass:'456'},
     {"_id":autoadd(),user:'b123',pass:'456'},
     {"_id":autoadd(),user:'c123',pass:'456'},
     {"_id":autoadd(),user:'d123',pass:'456'}]
   ).then((doc)=>{
     obj.aa=doc;
     //4,插入的数据结束后，更新下存储的自增数的集合，方便下次插入数据时，接着最新的索引。
     db.get('counters').findOneAndUpdate({sequence_value: (doc[0]["_id"])-1}, {sequence_value: doc[doc.length-1]["_id"]}).then(()=>{a();})
   });
});

—————————————————————

增

//为了集合添加一条文档
db.get('集合').insert([
 {
   "_id":autoadd(), //也可以执行函数
   post_title: filter.html2Escape(ctx.request.body.post_title),
   post_con: ctx.request.body.post_con,
   category:ctx.request.body.category,
   time:moment().format('YYYY-MM-DD kk:mm:ss')
 }
])

//同时添加多个文档
db.get('集合').insert([{ woot: 'bar' }, { woot: 'baz' }])

删

db.get('集合').remove()  //删除某集合下里面的所有文档
db.get('集合').remove({"_id":1});  //根据条件删除_id=1的文档

改

db.get('集合').update({name: '123'}, {$set :{num:456}}) //找到集合下含name=123的一个条文档，修改它字段num值为456

db.get('集合').update(
  { type : "book" },
  { $inc : { qty : 1 } },  //$inc是数字累加
  { multi: true }
)    //找到集合里面所有type=book的文档，让各自的文档中qty的字段累加1

查

db.get('集合').find({}).then((doc)=>{})  //获取到集合的所有文档
db.get('集合').find({"_id":1}).then((doc)=>{})  //只获取指定id的文档

//模糊搜索,搜索集合中的post_title字段或者post_con字段，若含有指定关键词，就选取出来相应的文档
db.get('集合').find({$or:[{"post_title":new RegExp(ctx.query['search[value]'],'ig')},{"post_con": new RegExp(ctx.query['search[value]'],'ig')}]})

//模糊搜索，搜索post集合，在集合的字段post_title或者post_con字段中如果含有value关键词,就选出所有符合条件的数据，
并且以字段_id的为准降序排列(数字大到小)，忽略前10条数据，从第11条数据开始，只显示5条数据，每条数据不显示post_con字段。
db.get('post').find({$or:[{"post_title":new RegExp(ctx.query['search[value]'],'ig')},{"post_con": new RegExp(ctx.query['search[value]'],'ig')}]}, 
 {
   fields: { post_con: 0 },
   sort: {"_id": -1},
   limit: 5,
   skip: 10
})


db.get('集合').count()  //条数
db.get('集合').count({name: 'foo'})  //返回字段name的值是foo的所有文档条数

findOne()  //不管数据多少，只显示一条数据
findOneAndDelete()  //不管数据多少，只找到一条数据并删除
findOneAndUpdate()

关闭与数据库连接

db.close()

centos 6.x手动安装编译nginx

centos安装nginx

1，下载nginx
http://nginx.org/download/nginx-1.11.12.tar.gz
http://nginx.org/en/download.html

2，安装Nginx所依赖的包：

gcc -v //查看系统是否安装gcc

rpm -qa | grep pcre 或者 pcre-config –version //是否安装pcre

rpm -qa | grep zlib //是否安装zlib

openssl version 或者 openssl version -a //是否安装（最低要求1.0.2）

wget https://www.openssl.org/source/openssl-1.1.0e.tar.gz
tar zxf openssl-1.1.0e.tar.gz

（一般情况下系统都会安装的）
yum -y install pcre*

yum -y install openssl*

yum -y install zlib*

3，切换到下载好的压缩包所在目录
例如：tar -zxvf nginx-1.11.12.tar.gz

4，查看openssl安装目录
一般在目录：
/usr/local/ssl
/usr/local/openssl
/usr/local/lib64 （我的在）

如果你是用rpm安装的
可以用命令
rpm -ql openssl

5，进入到解压好的nginx目录里面

关闭防火墙：service iptables stop
执行：

./configure --prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --with-openssl=/usr/lib64/openssl --with-http_stub_status_module --with-debug --with-http_ssl_module --with-http_realip_module --with-http_gzip_static_module --with-http_v2_module

别人的安装参数：

--with-cc-opt='-g -O2 -fPIE -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2'
--with-ld-opt='-Wl,-Bsymbolic-functions -fPIE -pie -Wl,-z,relro -Wl,-z,now'
--prefix=/usr/share/nginx
--conf-path=/etc/nginx/nginx.conf
--http-log-path=/var/log/nginx/access.log
--error-log-path=/var/log/nginx/error.log
--lock-path=/var/lock/nginx.lock
--pid-path=/run/nginx.pid
--http-client-body-temp-path=/var/lib/nginx/body
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi
--http-proxy-temp-path=/var/lib/nginx/proxy
--http-scgi-temp-path=/var/lib/nginx/scgi
--http-uwsgi-temp-path=/var/lib/nginx/uwsgi
--with-debug
--with-pcre-jit
--with-ipv6
--with-http_ssl_module
--with-http_stub_status_module
--with-http_realip_module
--with-http_auth_request_module
--with-http_addition_module
--with-http_dav_module
--with-http_geoip_module
--with-http_gunzip_module
--with-http_gzip_static_module
--with-http_image_filter_module
--with-http_v2_module
--with-http_sub_module
--with-http_xslt_module
--with-stream
--with-stream_ssl_module
--with-mail
--with-mail_ssl_module
--with-threads

6，接着编译
make && make install

7，启动nginx

cd /usr/local/nginx/sbin
/usr/local/nginx/sbin/nginx -V //查看版本和查看已安装模块
执行./nginx
启动：./nginx
停止：./nginx -s stop
重启：./nginx -s reopen
执行./nginx -h 可以看到命令的帮助信息

配置文件：
/nginx/nginx/conf/nginx.conf

8，加入系统托管，利用chkconfig控制

//执行文件名为：nginx

（注意路径）

#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions

# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"

RETVAL=0
prog="Nginx"

start() {
 echo -n $"Starting $prog: "
 mkdir -p /dev/shm/nginx_temp
 daemon $NGINX_SBIN -c $NGINX_CONF
 RETVAL=$?
 echo
 return $RETVAL
}

stop() {
 echo -n $"Stopping $prog: "
 killproc -p $NGINX_PID $NGINX_SBIN -TERM
 rm -rf /dev/shm/nginx_temp
 RETVAL=$?
 echo
 return $RETVAL
}

reload(){
 echo -n $"Reloading $prog: "
 killproc -p $NGINX_PID $NGINX_SBIN -HUP
 RETVAL=$?
 echo
 return $RETVAL
}

restart(){
 stop
 start
}

configtest(){
 $NGINX_SBIN -c $NGINX_CONF -t
 return 0
}

case "$1" in
 start)
 start
 ;;
 stop)
 stop
 ;;
 reload)
 reload
 ;;
 restart)
 restart
 ;;
 configtest)
 configtest
 ;;
 *)
 echo $"Usage: $0 {start|stop|reload|restart|configtest}"
 RETVAL=1
esac

exit $RETVAL

执行以下步骤：

cp nginx /etc/rc.d/init.d/

chmod 755 /etc/init.d/nginx

chkconfig –level 2345 nginx on

chkconfig –list nginx //2345都是on表示设置成功

 }





}

9，为nginx添加额外模块

(1)./nginx -V //获取到当前的参数

例如：
--prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --with-openssl=/root/openssl-1.1.0e --with-http_stub_status_module

(2)例如安装下载nginx-rtmp-module模块，去下载该模块解压获取到该模块的目录。

/root/nginx-rtmp-module-master  //解压后的路径

(3)在nginx根目录下看是否有configure文件，有可以进行安装，追加模块安装

./configure --prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --with-openssl=/root/openssl-1.1.0e --with-http_stub_status_module --add-module=/root/nginx-rtmp-module-master
make //在接着执行，千万不要执行make install

(4)到sbin目录下备份一下原来的nginx文件，例如改成nginx_bak

(5)到objs目录下把nginx复制到sbin目录中即可，之后到sbin目录执行./nginx -V看看是否追加了安装的模块
