tar -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_111
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export 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.gz
mv apache-tomcat-9.0.0.M15 tomcat

3. 安装ngnix

安装库

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

官方下载nginx-1.11.8.tar.gz

tar -zxvf nginx-1.11.8.tar.gz
cd nginx-1.11.8
useradd -s /sbin/nologin -M nginx
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module
make && make install
cd ..

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

vim /etc/init.d/nginx

写入

# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
   # make required directories
   user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   if [ -z "`grep $user /etc/passwd`" ]; then
       useradd -M -s /bin/nologin $user
   fi
   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}
stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}
restart() {
    configtest || return $?
    stop
    sleep 1
    start
}
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}
force_reload() {
    restart
}
configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
    status $prog
}
rh_status_q() {
    rh_status >/dev/null 2>&1
}
case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;

    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

修改权限

chmod 755 /etc/init.d/nginx

增加到服务

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

4. 安装mysql

检查旧版本mysql，然后移除

yum list installed | grep mysql
yum -y remove mysql-libs.x86_64
find / -name mysql
rm -rf /var/lib/mysql
rm -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.rpm
rpm -ivh mysql-community-release-el6-5.noarch.rpm
yum install mysql-server
service mysqld start
chkconfig mysqld on
mysql_secure_installation

5. redis安装

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

配置redis

vi redis/redis.conf

方便远程调式

line 70
bind 127.0.0.1
->
bind 0.0.0.0

设置为后台运行

line 136
daemonize 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 
->
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 = 511
vm.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/redis
chkconfig redis on

最后执行reboot完成
