Apollo

1、系统初始化# 关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
 
# 关闭selinux
sed -i 's/enforcing/disabled/' /etc/selinux/config #永久
setenforce 0 # 临时
 
# 关闭THP
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
 
# 时间同步
yum install ntpdate -y
ntpdate time.windows.com
echo "*/5 * * * * /usr/sbin/ntpdate ntp.api.bz >/dev/null 2 >&1" >> /var/spool/cron/root
 
2、安装JAVA环境tar -xzf jdk-11.0.9_linux-x64_bin.tar.gz -C /usr/local/
cd /usr/local/
mv jdk-11.0.9 java
 
启用环境变量:
cat << EOF >> /etc/profile
JAVA_HOME=/usr/local/java
JAVA_BIN=$JAVA_HOME/bin
PATH=$PATH:$JAVA_BIN
CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH
EOF
然后source 使其生效
ln -vs /usr/local/java/bin/java /usr/bin/java
source /etc/profile
java -version
3、安装并配置MySQLwget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar
rpm -qa | grep mariadb
rpm -e mariadb-libs-5.5.60-1.el7_5.x86_64 --nodeps
tar -xvf mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar
rpm -ivh mysql-community-common-8.0.28-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-libs-8.0.28-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-client-8.0.28-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-server-8.0.28-1.el7.x86_64.rpm --nodeps --force
 
rpm -qa | grep mysql
mysqld --initialize
chown mysql:mysql /var/lib/mysql -R
mkdir /data
mv /var/lib/mysql /data/
