Ghost博客安装

Ghost是基于Node.js的开源博客平台,由前WordPress UI部门主管John O’Nolan和WordPress高级工程(女)Hannah Wolfe创立,目的是为了给用户提供一种更加纯粹的内容写作与发布平台.
主机环境:

[root@test node-v0.10.40]# ./configure
[root@test node-v0.10.40]# make && make install
[root@test node-v0.10.40]# node -v
v0.10.40 //说明安装成功
安装mysql:
Ghost默认使用sqlite3数据库,对于一般使用足够了,但是内容多的话,就会拖慢整个系统,也就影响页面打开速度了,不想使用Mysql的朋友可以跳过这步.
mysql安装参考:https://www.tracymc.cn/archives/614(yum安装)、https://www.tracymc.cn/archives/218(编译安装)
[root@test node-v0.10.40]# mysql -u root -p

安装Ghost:
[root@test ~]# wget http://dl.ghostchina.com/Ghost-0.7.4-zh-full.zip
[root@test ~]# unzip Ghost-0.7.4-zh-full.zip -d ghost
[root@test ~]# cd ghost/
[root@test ghost]# cp config.example.js config.js
[root@test ghost]# vi config.js
Ghost有产品模式、开发模式和测试模式等多种运行模式,这里我们需要在配置文件中找到production模式:
// ### Production
// When running Ghost in the wild, use the production environment.
// Configure your URL and mail settings here
production: {
url: 'http://my-ghost-blog.com',
mail: {},
database: {
client: 'sqlite3',
connection: {
filename: path.join(__dirname, '/content/data/ghost.db')
},
debug: false
},

// 配置MySQL 数据库
/*database: {
client: 'mysql',
connection: {
host : 'host',
user : 'user',
password : 'password',
database : 'database',
charset : 'utf8'
},
debug: false
},*/

server: {
host: '127.0.0.1',
port: '2368'
},
修改为:
// ### Production
// When running Ghost in the wild, use the production environment.
// Configure your URL and mail settings here
production: {
url: 'http://1.2.3.4', //修改为你的域名或者IP,注意加上http://
mail: {},
/* database: { //从这开始注释
client: 'sqlite3',
connection: {
filename: path.join(__dirname, '/content/data/ghost.db')
},
debug: false
},*/ //注释结束,将sqlite3注释修改为mysql

// 配置MySQL 数据库
database: {
client: 'mysql',
connection: {
host : '127.0.0.1',
user : 'ghost',
password : '123456',
database : 'ghost',
charset : 'utf8'
},
debug: false
},

server: {
host: '127.0.0.1',
port: '80'
},

[root@test ghost]# npm start --production //首次启动

> ghost@0.7.4 start /root/ghost
> node index

Ghost is running in production...
Your blog is now available on http://127.0.0.1
Ctrl+C to shut down

浏览器输入127.0.0.1就可以访问博客了.Ctrl+C或者退出SSH终端进程就会停止.

前面提到的启动Ghost使用npm start –production命令.这是一个在开发模式下启动和测试的不错的选择.但是通过这种命令行启动的方式有个缺点.即当你关闭终端窗口或者从SSH断开连接时,Ghost就停止了.为了防止Ghost 停止工作,我们得解决这个问题.
以下有几种解决方案:
PM2(https://github.com/Unitech/pm2)
Forever (https://npmjs.org/package/forever)
Supervisor (http://supervisord.org/)

使用Forever:
[root@test ghost]# npm install forever -g //安装forever
[root@test ghost]# NODE_ENV=production forever start index.js //运行ghost,必须在/root/ghost目录下,不然会报错
[root@test ghost]# forever list //检测ghost是否在运行
info: Forever processes running
data: uid command script forever pid id logfile uptime
data: [0] jz38 /usr/local/bin/node index.js 31223 31225 /root/.forever/jz38.log 0:0:0:16.449
[root@test ghost]# forever stop index.js //停止ghost
info: Forever stopped process:
uid command script forever pid id logfile uptime
[0] jz38 /usr/local/bin/node index.js 31223 31225 /root/.forever/jz38.log 0:0:2:2.84
[root@test ghost]# forever list //没有进程信息了,说明ghost已停止
info: No forever processes running

使用supervisor:
supervisor安装配置参考:https://www.tracymc.cn/archives/599、https://www.tracymc.cn/archives/588
[root@test ghost]# vi /etc/supervisord.d/ghost.ini
[program:ghost]
command = node /root/ghost/index.js
directory = /root/ghost
user = root
autostart = true
autorestart = true
stdout_logfile = /var/log/supervisor/ghost.log
stderr_logfile = /var/log/supervisor/ghost_err.log
environment = NODE_ENV="production"
[root@test ghost]# supervisorctl start ghost //启动ghost
[root@test ghost]# supervisorctl status //查看ghost状态
cesi RUNNING pid 31284, uptime 0:00:36
ghost RUNNING pid 31285, uptime 0:00:36
tomcat RUNNING pid 31283, uptime 0:00:36
[root@test ghost]# supervisorctl stop ghost //停止ghost
ghost: stopped
[root@test ghost]# supervisorctl status //查看ghost状态
cesi RUNNING pid 31284, uptime 0:00:53
ghost STOPPED May 20 11:18 PM
tomcat RUNNING pid 31283, uptime 0:00:53
