Construction site springboard
The construction site springboards were divided into steel springboards and wooden springboards. Steel springboards were a type of construction equipment in the construction industry. They were also known as steel floorboards, construction steel springboards, steel footboards, zinc-coated steel springboards, hot-dip zinc-coated steel footboards, and so on. They were widely used in the shipbuilding industry, oil platforms, electricity, and construction industries. For example, the surface of the Bolin steel springboard had protruding holes, which could enhance the friction, effectively prevent slipping, prevent sand accumulation, and have high strength. It could withstand 5 - 6 people standing without being deformed. It was sturdy and durable. Its unique shape design made it easier to bundle and install. When it was free, it was stacked neatly, which was beneficial to the 5S management on the spot. When choosing a wooden springboard, you need to pay attention to the quality of the wood. You should choose a wood with uniform material, no cracks, and no bug holes to ensure strength and durability. You should also choose the appropriate size according to the actual needs of the construction site to ensure safety.

The function of the springboard at the construction site
The construction site springboard had many important functions in construction. For steel springboards, they were stronger and could withstand multiple people standing without being deformed. For example, the Boleyn steel springboard could withstand five to six people standing at the same time. The surface of the board has protruding holes, which can enhance the friction to achieve effective anti-slip and anti-sand effects. Its unique shape design makes it easier to bundle and install. When it is free, it can be stacked neatly, which is conducive to 5S management on the spot. Steel springboards were widely used in the shipbuilding industry, oil platforms, electric power, construction industry, etc. They were an important part of the construction site's workmanship. In terms of wooden springboards, they could be used as a channel for workers to walk and work in different areas of the construction site, making it convenient for construction workers to reach the corresponding construction location. For example, they were needed in bridge construction, building pouring cement, and other work scenes. When choosing a wooden springboard, you need to pay attention to the quality of the wood, such as choosing a uniform material, no cracks, and no bug holes to ensure its strength and durability. At the same time, you need to choose the appropriate size according to the actual needs of the construction site to ensure safety.

A springboard or a seesaw used at the construction site
A springboard was usually used on construction sites. A springboard was a long board that was temporarily built for construction workers to walk or carry materials. It was usually built on a falsework or support structure to facilitate the movement of workers between different work areas or up and down when working at high altitudes. Rockers were rarely used on construction sites. Rockers appeared more in the context of children's amusement facilities and electronic switches (such as the Rocker Switch).

What's the use of a construction site springboard?
On a construction site, a springboard was a construction tool. The springboards were divided into steel springboards and wooden springboards. The steel springboard could be used to construct the platform. It had bolt holes for connecting the boards to adjust the width of the bottom of the platform. The boards were fixed with skirting boards. After the connection between the steel springboards was completed, the materials used to make the platform had to be strictly inspected. After the platform was completed, it had to be tested, installed, and inspected before it could be put into use. It could withstand many people standing without being deformed, and was sturdy and durable. The surface of the board had protruding holes to prevent slipping and sand accumulation. Its unique shape design was easy to bundle, hang, and install. It was easy to stack neatly when idle, which was beneficial to on-site management. The wooden springboard was a facility for people to walk around, operate, and place tools and materials during construction. The processing process was exquisite. These springboards provided the construction workers with a flat surface to work on and pass through during the construction process, which was helpful for the construction of various operations.

What does the springboard on the construction site mean?
On the construction site, springboards were a type of construction material. For example, bamboo springboards could be used as footboards, bamboo fences, bamboo frame boards, etc. They could be used as temporary passages and work platforms for workers to move or work between building structures. Just like the hamster jumping platform springboard was a pet pedal toy, the springboard on the construction site provided a convenient place for workers to step on.

Springboard machine construction
The following are some common steps for building a springboard machine: ** 1. Prepare the environment ** 1. ** System environment settings (CentOS as an example)** - Defense mechanism deactivated: - In the CentOS system, use the command `setenforce0` and `sed -i '7s/enforcing/disabled/'/etc/selinux/configuration` to modify the configuration of the SELinux-based system. Then, stop the firewall and set it to not start, such as `systemvl stop firewalld` and `systemvl disable firewalld`. - Changing the character set (to prevent input/output error): - Execute `localadef-c -f UTF - 8 -i zh_GN zh_GN.UTF - 8`, then `export LV_ALL = zh_GN.UTF - 8`, and write `LANG ="zh_GN.UTF - 8"` to `/etc/locale.conf`. - To install the dependent package: - For example, in CentOS, use `yum-y install epel - release` to update the software source, then use `yum-y update` to update the system, and then install the dependent packages such as `git python-pip mysql-devel gcc automake autoconf python-devel vim sshpass lrzz readline-devel`. 2. ** Installs necessary software (like Jumpserver)** - Downloading Jumpserver related files, such as `tar - zvxf jumpserver3.0.tar.gz - C /usr/Src`, and then enter the relevant `CD jumpserver` and then the `install/` folder. - Use `pip install --upgrade pip -r requirements. txt-i to install the relevant components. You can also use`pip freeze`to view all the installed software. - To install and start MariaDB (Database-related operations): - Use `yum-y install mariadb mariadb-server` to install,`systemvl start mariadb` to start, and `systemvl enable mariadb` to boot. - Simple configuration of MariaDB, such as setting the password (using `mysql-secure-installation`), and setting the character set (add `init_connect ='Set collection_connection = utf8-unicode-ci'` in the relevant configuration files such as `/etc/my. ccnf'). ** 2. User and permission settings (CentOS as an example)** 1. ** Create a springboard machine user and group ** - First, create a user and a group. For example,`user add tiaobanji` creates a user, and `user mod-s/sbin/nologin tiaobanji` sets the user not to log into the system (for security reasons). You can also use scripts to create springboard users and initiate them. For example, custom scripts can add users in batches, set default passwords, and so on. ** 3. Identity verification (Take Pagant as an example)** 1. ** Pagant and PuTTY operations (applicable to the springboard machine for the SSH-connection)** - The prerequisite was that Pagant was installed with the PuTTY suite and that the local computer had saved at least one Shh key. - Start Pagant from the PuTTY folder. By default, Pagant will be minimized in the system tray. Right-click its icon and select `Add Key` or `View Key` to open the `Pagant Key List` window to add a key (select a file with the extension.ppk). If the key is password-protected, you only need to enter the password once to add it to the key list. - When connecting to the springboard machine through PuTTY, select the "Allow agent shipping" option under the SSH-Auth folder on the left. This way, the ssh client on the springboard machine can communicate with the local ssh-agent and use the local key to complete the ssh authentication process with the managed server. ** 4. Connecting the springboard machine to the server ** 1. ** Connecting to the server from the springboard machine (using Aws's EC2 as an example)** - Use the command `ssh ec2 - user@ server private IP address` to access the managed server from the springboard (enter the private IP address of the managed server here).

System environment preparation (CentOS as an example)** 1. * * Shut down the defense mechanism ** - Execution order: - `setenforce 0` - Use `sed-i '7s/enforcing/disabled/'/etc/selinux/configuration` to modify the configuration file. - `systemvl stop firewall` Stop firewall service - `systemvl disable firewall` prevents the firewall from starting up automatically. 2. * * Modifies character set (to prevent input/output error)** - Execution order: - `localedef -c -f UTF - 8 -i zh_CN zh_CN.UTF - 8` - `export LC_ALL = zh_CN.UTF - 8` - Write `LANG ="zh_GN. UTF-8" into the``/etc/locale.conf `file. 3. * * Installs the dependent package ** - Execution order: - `yum -y install epel - release` - `yum -y update` - `yum -y install git python - pip mysql - devel gcc automake autoconf python - devel vim sshpass lrzsz readline - devel` * * 2. Installs Jumpserver (Jumpserver 3.0 as an example)** 1. * * Unzip the installation package ** - Assuming that the installation package is `jumpserver 3.0.tar.gz`, execute the command `tar-zvxf jumpserver 3.0.tar.gz-C/usr/Src`, and then enter the unzipped `CD jumpserver` and the `install/`. 2. * * Use Quick Installment Script ** - Execute the command `pip install--upgrade pip-r requirements.txt-https://pypi.tuna.tsinghua.edu.conn/simple`. After that, you can use `pip freeze` to check all the installed software. * * Third, install and start MariaDB (Database-related configuration)** 1. * * Installs and starts ** - Execute the command `yum-y install mariadb mariadb-server` - Start service: `systemvl start mariadb` - Set the boot-up function: `systemvl enable mariadb` 2. * * Simple configuration of MariaDB (password setting)** - Execute `mysql-secure-installation` and follow the prompts: Enter directly, enter `Y-enter to set the password (follow the prompts), enter whether to delete anonymous users, enter whether to prohibit root remote login (set according to the situation), enter whether to delete the test database, enter whether to reload the permission table. 3. * * Test login ** - Assuming the password is 123456, execute the command `mysql-uroot-p123456`. 4. * * Configures the character set of MariaDB ** - For the `/etc/my.cnf `file (added under the`(mysqld)`tag): - Back up `ep/etc/my. ckf {,. bak}` first. - Added content: - `init_connect =‘SET collation_connection = utf8_unicode_ci’` - `init_connect =‘SET NAMES utf8’` - `character - set - server = utf8` - `collation - server = utf8_unicode_ci` - `skip - character - set - client - handshake` - For the `/etc/my.cnf.d/client.cnf `file (add in`(client)`): - Back up `CP/etc/my.cnf.d/client.cnf {,. bak}` first - Add `default-character-set = utf8`. - For the configuration file `/etc/my.cnf. d/mysql-clients.cnf `(add relevant content in`(mysql)`). * * 4. User settings of the springboard console (CentOS6.7 as an example)** 1. * * Create a springboard machine user and group ** - First, create a user and a group. For example, create a `tiaobanji` user and a `tiaobanji` group. Then, execute the command: - `useradd tiaobanji` - `username-s/sbin/nologin tiaobanji`(For security reasons, the user is not allowed to log into the system). - You can also create a springboard machine user through the script that comes with the project (such as `add_user. sh `) and perform operations such as initialisation. In addition, if it involves connecting to the springboard machine through Pagant (PuTTY authentication agent): 1. * * Prerequisite ** - Make sure that Pagant is installed with the PuTTY suite and that you have saved at least one Shh key on your local computer. 2. * * Add the secret key to Pagant ** - Start Pagant from the PuTTY folder. By default, Pagant will be minimized in the system tray. - Right-click its icon and select `Add Key` or `View Key` to open the `Pagant Key List` window, where you can view, add, and delete keys. When adding the key, select a file with the extension `. ppk`. If the key is password-protected, you need to enter the password. 3. * * Landing the springboard machine through Putty ** - These keys will be available when you connect to any server during a PuTTY session. Enter the host name or IP address, as well as the ssh user, and select the "Allow agent shipping" option under the SSH-Auth folder on the left. This option will allow the ssh client on the springboard to communicate with the local ssh-agent of the management terminal to complete the subsequent operations.> While watching the Olympics, you can also read the wonderful novels related to the Olympics!
