环境部署
1.在官方网站下载最新版本python3.8.5
wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tgz
tar -zxvf Python-3.8.5.tgz
mkdir /usr/local/python38
cd Python-3.8.1
./configure --prefix=/usr/local/python38 --enable-optimizations --with-ssl
make && make install
ln -s /usr/local/python38/bin/python3 /usr/bin/python3
ln -s /usr/local/python38/bin/pip3 /usr/bin/pip3
pip3 install --upgrade pip
注意：python版本需要大于3.8.2
注意：安装更高版本python时候，软连接过程中yum脚本内容会自动发生变化导致错误，需提前做好备份。
2.主机配置
echo "192.168.1.156 tdsql01">> /etc/hosts
echo "192.168.1.157 tdsql02">> /etc/hosts
echo "192.168.1.158 tdsql03">> /etc/hosts
echo "192.168.1.159 tdsql04">> /etc/hosts
3.磁盘挂载
pvcreate /dev/vdb
vgcreate tdsql_vg /dev/vdb
lvcreate -L 160G -n data tdsql_vg
lvcreate -l 100%FREE -n data1 tdsql_vg
mkfs.ext4 /dev/tdsql_vg/data
mkfs.ext4 /dev/tdsql_vg/data1
mkdir /data
mkdir /data1
mount /dev/tdsql_vg/data /data
mount /dev/tdsql_vg/data1 /data1
mount -o remount /data
mount -o remount /data1
cat >> /etc/fstab << EOF
/dev/tdsql_vg/data /data ext4 defaults 0 0
/dev/tdsql_vg/data1 /data1 ext4 defaults 0 0
EOF
cat /etc/fstab
3.关闭防火墙和selinux
systemctl status firewalld
systemctl disable firewalld
systemctl stop firewalld
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/sysconfig/selinux
4. sysctl配置
cat >> /etc/sysctl.conf << EOF
fs.aio-max-nr = 1048576
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 1024 65535
vm.swappiness=1
vm.min_free_kbytes=204800
vm.overcommit_memory = 1
net.core.somaxconn = 20480
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
net.ipv6.conf.all.disable_ipv6 = 1
net.core.wmem_default = 256960
net.core.rmem_default = 256960
net.core.wmem_max = 2097152
net.core.rmem_max = 2097152
net.ipv4.tcp_wmem = 8760 256960 4088000
net.ipv4.tcp_rmem = 8760 256960 4088000
net.ipv4.tcp_mem = 786432 2097152 3145728
EOF
sysctl -p
5.limit配置
systemctl set-default multi-user.target
cat > /etc/security/limits.conf << EOF
* soft nproc 1048576
* hard nproc 1048576
* soft nofile 1048576
* hard nofile 1048576
* soft stack 10240
* hard stack 32768
EOF
6.时间同步配置
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
hwclock
yum -y
yum list installed chrony
systemctl status chronyd
systemctl enable chronyd
systemctl start chronyd
systemctl status chronyd
vi /etc/chrony.conf
#pool pool.ntp.org iburst
server 192.168.1.21 iburst
注意：服务端需要允许其它客户端访问。
检查时钟同步情况
chronyc sources -v
7.yum源配置
cat >> /etc/yum.repos.d/local.repo << EOF
[local]
name=local
baseurl=file:///mnt
enabled=1
