leanote安装配置 环境：

     Centos 6.5 x86_64

所需软件：

     go1.8.linux-amd64.tar.gz

     mongodb-linux-x86_64-rhel62-3.4.4.tgz

     leanote-all-master.zip

     nginx-1.12.1.tar.gz

     setuptools-36.2.7.zip

     supervisor-3.3.3.tar.gz

一、安装go

1、解压

tar  zxvf  go1.8.linux-amd64.tar.gz  -C  /usr/local/

2、新建目录mygo，放go的模块及编译后的文件

mkdir  /usr/local/mygo

3、配置环境变量

vi  /etc/profile
    添加以下内容：

GOROOT=/usr/local/go
GOPATH=/usr/local/mygo
PATH=$PATH:$GOROOT/bin:$GOPATH/bin
export GOROOT GOPATH PATH

使环境变量生效

source  /etc/profile

4、验证

go  version

二、安装revel

1、 解压leanote-all-master.zip

unzip  leanote-all-master.zip

2、 把src文件放到/usr/local/mygo中

cp  –rf  leanote-all-master/src  /usr/local/mygo/

3、 安装

cd  /usr/local/mygo/src  && go  install  github.com/revel/cmd/revel

三、安装mongodb

1、解压并重命名解压目录

tar  zxvf  mongodb-linux-x86_64-rhel62-3.4.4.tgz  -C  /usr/local
mv  /usr/local/mongodb-linux-x86_64-rhel62-3.4.4  /usr/local/mongodb

2、添加环境变量

vi  /etc/profile

当前的环境配置如下：

GOROOT=/usr/local/go
GOPATH=/usr/local/mygo
MONGO=/usr/local/mongodb
PATH=$PATH:$GOROOT/bin:$GOPATH/bin:$MONGO/bin
export GOROOT GOPATH PATH

使环境变量生效

source  /etc/profile

3、新建数据存放目录

mkdir  /usr/local/data

4、启动数据库

mongod --dbpath /usr/local/data

5、导入数据

mongorestore -h localhost -d leanote –dir /usr/local/mygo/src/github.com/leanote/leanote/mongodb_backup/leanote_install_data

四、配置leanote

修改/usr/local/mygo/src/github.com/leanote/leanote/conf/app.conf

http.port=9000修改为http.port=8080
site.url=http://localhost:9000修改为site.url=http://10.188.12.133:8080
更改app.secret后面的字符串，总长度保持不变

五、启动leanote

revel run github.com/leanote/leanote

六、访问

浏览器地址栏输入http://10.188.12.133:8080，登录，默认用户名admin，密码abc123

现在密码：zeroc.net

扩展

（一）为leanote配置数据库用户密码

1、修改/usr/local/mygo/src/github.com/leanote/leanote/conf/app.conf

db.dbname=修改为db.username=ZeroC
db.password修改为db.password=toor

2、启动mongodb

mongod  --dbpath  /usr/local/data

3、登录mongodb（另一个终端中）

mongo

4、添加ZeroC用户（>开头的为命令，##为注释，#为shell命令，其他为返回值）

##切换到leanote数据库
>use leanote
switched to db leanote
##添加ZeroC用户，密码为toor，角色为readWrite
>db.createUser({user:"ZeroC",pwd:"toor",roles:["readWrite"]});
Successfully added user: { "user" : "ZeroC", "roles" : [ "readWrite" ] }
##停止mongo
>use admin;
>db.shutdownServer()
>exit

启动mongodb

mongod  --dbpath  /usr/local/data --auth

登录mongodb，并切换到leanote数据库

##此时查看数据表会失败
>show collections;
2017-08-02T21:46:56.166+0800 E QUERY    [thread1] Error: listCollections failed: {
         "ok" : 0,
         "errmsg" : "not authorized on leanote to execute command { listCollections: 1.0, filter: {} }",
         "code" : 13,
         "codeName" : "Unauthorized"
} :

##认证
> db.auth("ZeroC","toor");
1
##再看表
>show collections;
albums
attachs
blog_comments
blog_likes

……

5、启动leanote

revel run github.com/leanote/leanote

（二）修改admin的邮箱

1、登录mongodb

mongo

2、更新数据

##切换到leanote数据库
>use leanote;
switched to db leanote
##认证
> db.auth("ZeroC","toor");
1
##查看数据
>db.users.find({Username:"admin"})
##修改邮箱
>db.users.update({Username:"admin"},{$set:{Email:"vrocwang@gmail.com"}})

（三）以后台方式启动mongodb

说明：如果已经启动过mongodb，那么需要清理掉数据文件，不然启动会报错

为方便操作，把启动选项放进配置文件中

1、新建conf，log目录

mkdir  /usr/local/mongodb/{conf,log}

2、添加配置文件

cat  /usr/local/mongodb/conf/mongodb.conf
dbpath=/usr/local/data
logpath=/usr/local/mongodb/log/log
pidfilepath=/usr/local/mongodb/conf/mongo.pid
## 为每一个数据库按照数据库名建立文件夹存放
directoryperdb=true
## 以追加的方式记录日志
logappend=true
## 绑定ip
bind_ip=127.0.0.1
## 端口
port=27017
## 日志文件的最大大小。单位为Mb，默认为硬盘剩余空间的5%
oplogSize=1000
## 后台运行
fork=true
## 不预先分配存储
noprealloc=true
## 认证方式启动
auth=true

3、启动

mongod  -f  /usr/local/mongodb/conf/mongodb.conf

（四）为admin添加用户

注意：此处不要以认证方式启动，不然，无法操作admin数据库，因为mongodb默认没有管理员用户，无法认证

1、登录mongodb

mongo

2、切换到admin库

>use admin;

3、查看admin库中的表

> show collections;
system.users
system.version

4、查看用户(默认为空)

> db.system.users.find()

5、添加数据库管理员

>db.createUser({user:"admin",pwd:"toor",roles:["readWriteAnyDatabase","dbAdminAnyDatabase","clusterAdmin"]})

（五）用supervisor管理leanote，使leanote后台运行

supervisor是python的一个模块，需要先安装setuptools

1、解压setuptools，并安装

unzip setuptools-36.2.7.zip
cd setuptools-36.2.7
python setup.py install

2、解压supervisor，并安装

tar zxvf supervisor-3.3.3.tar.gz
cd supervisor-3.3.3
python setup.py install

3、配置supervisor （##开头的行为说明）

①新建目录

mkdir -p /usr/local/supervisor/logs

②生成配置文件，echo_supervisord_conf 在/usr/bin中

echo_supervisord_conf  > /usr/local/supervisor/supervisord.conf

③修改配置文件如下

[root@ZeroC supervisor]# sed -e "/^;/d" -e "/^$/d" supervisord.conf 
[unix_http_server]
file=/usr/local/supervisor/supervisor.sock ; the path to the socket file
chmod=0700 ; socket file mode (default 0700)
[supervisord]
logfile=/usr/local/supervisor/logs/supervisord.log ; main log file; default $CWD/supervisord.log
logfile_maxbytes=50MB ; max main logfile bytes b4 rotation; default 50MB
logfile_backups=10 ; # of main logfile backups; 0 means none, default 10
loglevel=info ; log level; default info; others: debug,warn,trace
pidfile=/usr/local/supervisor/supervisord.pid ; supervisord pidfile; default supervisord.pid
nodaemon=false ; start in foreground if true; default false
minfds=1024 ; min. avail startup file descriptors; default 1024
minprocs=200 ; min. avail process descriptors;default 200
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///usr/local/supervisor/supervisor.sock ; use a unix:// URL for a unix socket
[include]
files = /usr/local/supervisor/*.ini
④添加leanote的配置文件/usr/local/supervisor/leanote.ini，内容如下

[program:leanote]
command=/usr/local/mygo/bin/revel run github.com/leanote/leanote
directory=/usr/local/mygo/src
autorstart=true
redirect_stderr=true
stdout_logfile=/usr/local/supervisor/logs/leanote.log
user=root
priority=1

⑤启动supervisor

supervisord -c /usr/local/supervisor/supervisord.conf
supervisorctl start all

（六）导出leanote数据文件

mongodump -h 127.0.0.1 -u ZeroC -p toor -d leanote -o /root/data

注意：如果用auth模式启动，无备份权限无法备份数据库

报错如下：

2017-11-30T11:15:26.732+0800	Failed: error getting database names: not authorized on admin to execute command { listDatabases: 1 }
