阿里云ECS初试-安装

入手了一台16核128G 100M CentOS 6.8

cd /usr/local

1. 安装jdk

官方下载jdk-8u111-linux-x64.tar.gz

mkdir javatar -zxvf jdk-8u111-linux-x64.tar.gz -C java

配置环境变量

vi /etc/profile.d/jvm.sh

内容写入

JAVA_HOME=/usr/local/java/jdk1.8.0_111CLASSPATH=$JAVA_HOME/lib/PATH=$PATH:$JAVA_HOME/binexport PATH JAVA_HOME CLASSPATH

2. 安装tomcat

官方下载apache-tomcat-9.0.0.M15.tar.gz

tar -zxvf apache-tomcat-9.0.0.M15.tar.gzmv apache-tomcat-9.0.0.M15 tomcat

3. 安装ngnix

安装库

yum install pcre pcre-devel -yyum install openssl openssl-devel -y

官方下载nginx-1.11.8.tar.gz

tar -zxvf nginx-1.11.8.tar.gzcd nginx-1.11.8useradd -s /sbin/nologin -M nginx./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_modulemake && make installcd ..

配置脚本
参考https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/

vim /etc/init.d/nginx

写入

修改权限

chmod 755 /etc/init.d/nginx

增加到服务

chkconfig --add /etc/init.d/nginxchkconfig nginx on

4. 安装mysql

检查旧版本mysql，然后移除

yum list installed | grep mysqlyum -y remove mysql-libs.x86_64find / -name mysqlrm -rf /var/lib/mysqlrm -rf /etc/my.cnf  #这个玩意不会被自动移除

开始安装

wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpmrpm -ivh mysql-community-release-el6-5.noarch.rpmyum install mysql-serverservice mysqld startchkconfig mysqld onmysql_secure_installation

5. redis安装

tar -zxvf redis-4.0.1.tar.gzcd redis-4.0.1make && make install PREFIX=/usr/local/rediscd ..cp redis-4.0.1/redis.conf redis/

配置redis

vi redis/redis.conf

方便远程调式

line 70bind 127.0.0.1->bind 0.0.0.0

设置为后台运行

line 136daemonize no->daemonize yes

设置密码

line 500# requirepass foobared->requirepass 新密码

设置redis最大内存使用，默认是不限

line 559# maxmemory <bytes>->maxmemory 68719476736

内存策略

line 590# maxmemory-policy noeviction->maxmemory-policy volatile-ttl

安装完毕后发现有3个WARNING
1. WARNING: The TCP backlog setting of 511 ……
2. WARNING overcommit_memory is set to 0! Backgr ……
3. WARNING you have Transparent Huge Pages (THP) support ……
解决#1,2

vi /etc/sysctl.conf

追加内容

net.core.somaxconn = 511vm.overcommit_memory=1

保存后使之生效

sysctl -p

解决#3

vi /etc/rc.local

追加内容

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then     echo never > /sys/kernel/mm/transparent_hugepage/enabled  fi  if test -f /sys/kernel/mm/transparent_hugepage/defrag; then     echo never > /sys/kernel/mm/transparent_hugepage/defrag  fi  

配置写脚本

vi /etc/init.d/redis

内容

PATH=/usr/local/bin:/sbin:/usr/bin:/bin   REDISPORT=6379  EXEC=/usr/local/redis/bin/redis-server   REDIS_CLI=/usr/local/redis/bin/redis-cli   PIDFILE=/var/run/redis.pid   CONF="/usr/local/redis/redis.conf"  case "$1" in           start)                   if [ -f $PIDFILE ]                   then                           echo "$PIDFILE exists, process is already running or crashed."                  else                          echo "Starting Redis server..."                          $EXEC $CONF                   fi                   if [ "$?"="0" ]                   then                           echo "Redis is running..."                  fi                   ;;           stop)                   if [ ! -f $PIDFILE ]                   then                           echo "$PIDFILE exists, process is not running."                  else                          PID=$(cat $PIDFILE)                           echo "Stopping..."                         $REDIS_CLI -p $REDISPORT  SHUTDOWN                            sleep 2                         while [ -x $PIDFILE ]                          do                                  echo "Waiting for Redis to shutdown..."                                 sleep 1                          done                           echo "Redis stopped"                  fi                   ;;           restart|force-reload)                   ${0} stop                   ${0} start                   ;;           *)                  echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2                  exit 1  esac

修改权限

chmod 755 /etc/init.d/redis

增加到服务

chkconfig --add /etc/init.d/redischkconfig redis on

最后执行reboot完成
