设置本地编码

要将 CentOS 的本地区域设置更改为 `zh_CN.UTF-8`（中文简体UTF-8编码），你可以执行以下步骤：

1. 打开终端并以超级用户（root）权限登录，或者使用 sudo 进行操作。

2. 首先，查看可用的语言和区域设置：
localectl list-locales
确保 `zh_CN.UTF-8` 在列表中。

3. 设置系统的语言和区域设置为 `zh_CN.UTF-8`：
localectl set-locale LANG=zh_CN.UTF-8

4. 更新系统的区域设置配置：
source /etc/locale.conf

5. 重启系统以使更改生效：
reboot

在系统重新启动后，你的本地区域设置应该已经更改为 `zh_CN.UTF-8`。这将影响系统的界面语言、日期格式和其他相关设置。请注意，这仅更改系统级别的区域设置。对于特定用户的区域设置，可以使用 `~/.bashrc` 或 `~/.bash_profile` 文件进行自定义。

修改主机名

hostnamectl set-hostname master
#reboot

修改hosts

$ vim /etc/hosts                   
# 添加如下内容
    10.0.1.9 master
    10.0.1.5 node1

优化sshd

echo 'UseDNS no' >> /etc/ssh/sshd_config; systemctl restart sshd
yum update -y ca-certificates

优化sysctl参数、limits参数、systemd参数

</code></pre><h1>设置本地编码</h1><pre><code>要将 CentOS 的本地区域设置更改为 `zh_CN.UTF-8`（中文简体UTF-8编码），你可以执行以下步骤：

1. 打开终端并以超级用户（root）权限登录，或者使用 sudo 进行操作。

2. 首先，查看可用的语言和区域设置：
localectl list-locales
确保 `zh_CN.UTF-8` 在列表中。

3. 设置系统的语言和区域设置为 `zh_CN.UTF-8`：
localectl set-locale LANG=zh_CN.UTF-8

4. 更新系统的区域设置配置：
source /etc/locale.conf

5. 重启系统以使更改生效：
reboot

在系统重新启动后，你的本地区域设置应该已经更改为 `zh_CN.UTF-8`。这将影响系统的界面语言、日期格式和其他相关设置。请注意，这仅更改系统级别的区域设置。对于特定用户的区域设置，可以使用 `~/.bashrc` 或 `~/.bash_profile` 文件进行自定义。</code></pre><h1>修改主机名</h1><pre><code>hostnamectl set-hostname master
