将linux核心更改为BBR愿景

如果您的服务器是新服务器，强烈建议将其更新到支持bbr模式的较高版本，这是google提供的高级centos系统核心，它可以使您的服务器更高效。

首先从github下载并安装bbr core。

1
2
3
$ wget -N --no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh &&\
$ chmod +x bbr.sh && \
$ bash bbr.sh

使用代码检查核心版本。 如果大于4.9.0，则可以。

1
$ uname -r

预期显示:net.ipv4.tcp_available_congestion_control = bbr cubic reno

1
$ sysctl net.ipv4.tcp_available_congestion_control

预期显示: net.ipv4.tcp_congestion_control = bbr

1
$ sysctl net.ipv4.tcp_congestion_control

预期显示: net.core.default_qdisc = fq

1
$ sysctl net.core.default_qdisc

预期显示: xxxxxxxx tcp_bbr

1
$ lsmod | grep bbr

##安装Nginx服务

从nginx组织网站上提取nginx软件包。

1
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

安装 Nginx.

1
$ yum install -y nginx

启动 nginx .

1
2
$ systemctl start nginx.service
$ systemctl enable nginx.service

设置nginx的首选项文件。 单击此处以获取推荐的nginx.conf文件。

1
2
$ cd /etc/nginx
$ vi nginx.conf

申请ssl认证。 用your_domain.crt（key）重命名并将其下载到服务器：/ etc / nginx / ssl /

1
2
3
$ //Use scp -r (my ssl file route on my windows)/your_domain.crt \root@(your server ip): /etc/nginx/ssl
$ //Use scp -r (my ssl file route on my windows)/your_domain.crt root@(your server ip): /etc/nginx/ssl
$ //On WINDOWS BASH

检查并重新启动Nginx服务。

1
2
3
4
$ nginx -t

$ //If the return is successful it is ok, othervise there exists error in your nginx.conf file. 
$ systemctl restart nginx

##安装docker

从官方网站拉并安装docker服务。

1
$ curl -sSL https://get.docker.com/ | sh

启动docker服务

1
2
$ systemctl start docker
$ systemctl enable docker.service

从github提取nextcloud和mariadb（centos上的简化mysql数据库）图像。

1
$ docker pull rootlogin/nextcloud && docker pull mariadb:10

使用Docker启动映像mariadb。

1
2
3
$ docker run -d --name nextcloud_db -v /data/mysql:/var/lib/mysql -e \
$ MYSQL_ROOT_PASSWORD=YOUR_PASSWD -e MYSQL_DATABASE=nextcloud \
$ -e MYSQL_USER=nextcloud -e MYSQL_PASSWORD=YOURPASSWD mariadb:10

使用docker启动映像nextcloud。

1
$ docker run -d --name nextcloud --link nextcloud_db:nextcloud_db -p 127.0.0.1:9001:80 -v /data/nextcloud:/data rootlogin/nextcloud

那是服务器上的最后一步。 现在，从浏览器开始http：// YOUR_DOMAIN /。

建议将“ localhost”替换为“ nextcloud_db”。

Change linux core to BBR vision

If your server is a new one, it is strongly recommended to update it to an upper version supporting bbr mode, which is a senior centos system core provide by google and it could make your server more efficient.

Firstly download and install bbr core from github.

1
2
3
$ wget -N --no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh &&\
$ chmod +x bbr.sh && \
$ bash bbr.sh

Use the code to check the core version. If it’s large than 4.9.0 it’s OK.

1
$ uname -r

Expected return:net.ipv4.tcp_available_congestion_control = bbr cubic reno

1
$ sysctl net.ipv4.tcp_available_congestion_control

Expected return: net.ipv4.tcp_congestion_control = bbr

1
$ sysctl net.ipv4.tcp_congestion_control

Expected return: net.core.default_qdisc = fq

1
$ sysctl net.core.default_qdisc

Expected return: xxxxxxxx tcp_bbr

1
$ lsmod | grep bbr

Install Nginx Service

Pull nginx package from nginx orginzation website.

1
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

Install Nginx.

1
$ yum install -y nginx

Start nginx service.

1
2
$ systemctl start nginx.service
$ systemctl enable nginx.service

Set preference file of nginx. Click here to get recommended nginx.conf file.

1
2
$ cd /etc/nginx
$ vi nginx.conf

Apply ssl certification. Rename it with your_domain.crt(key) and download it to your server: /etc/nginx/ssl/

1
2
3
$ //Use scp -r (my ssl file route on my windows)/your_domain.crt \root@(your server ip): /etc/nginx/ssl
$ //Use scp -r (my ssl file route on my windows)/your_domain.crt root@(your server ip): /etc/nginx/ssl
$ //On WINDOWS BASH

Check and restart nginx service.

$ nginx -t

$ //If the return is successful it is ok, othervise there exists error in your nginx.conf file. 
$ systemctl restart nginx

Install docker

Pull and install docker service from official website.

1
$ curl -sSL https://get.docker.com/ | sh

Start docker service.

1
2
$ systemctl start docker
$ systemctl enable docker.service

Pull nextcloud and mariadb(simplified mysql database on centos ) images from github.

1
$ docker pull rootlogin/nextcloud && docker pull mariadb:10

Start image mariadb with docker.

1
2
3
$ docker run -d --name nextcloud_db -v /data/mysql:/var/lib/mysql -e \
$ MYSQL_ROOT_PASSWORD=YOUR_PASSWD -e MYSQL_DATABASE=nextcloud \
$ -e MYSQL_USER=nextcloud -e MYSQL_PASSWORD=YOURPASSWD mariadb:10

Start image nextcloud with docker.

1
$ docker run -d --name nextcloud --link nextcloud_db:nextcloud_db -p 127.0.0.1:9001:80 -v /data/nextcloud:/data rootlogin/nextcloud

That is the last step on server. Now let’s start http://YOUR_DOMAIN/ with your explorer.

Recommend to substitute the “localhost” to “nextcloud_db”.
