二、调整Linux设置

2.1、调整DNS

1)编辑DNS

[root@localhost ~]# vi /etc/resolv.conf
[root@localhost ~]# cat /etc/resolv.conf
#阿里云 DNS
nameserver 223.5.5.5
nameserver 223.6.6.6

#Google DNS
nameserver 8.8.8.8

2)重启网络服务

[root@localhost ~]# service network restart
正在关闭接口 em2：                                         [确定]
关闭环回接口：                                             [确定]
弹出环回接口：                                             [确定]
弹出界面 em2： Determining if ip address 221.235.184.199 is already in use for device em2...
                                                           [确定]

2.2、调整软件源

[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
[root@localhost ~]# wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/Centos-6.repo
[root@localhost ~]# yum makecache

如果无wget命令，则手动编辑。

2.3、安装ntp ，用于同步系统时间

1)安装并启动

[root@localhost ~]# yum -y install ntp

2)同步时间

[root@localhost ~]# ntpdate time.nuri.net
23 Dec 21:13:45 ntpdate[30444]: adjust time server 211.115.194.21 offset -0.020057 sec

3)增加时间服务器, time.nuri.net

[root@localhost ~]# vi /etc/ntp.conf
[root@localhost ~]# cat /etc/ntp.conf
# For more information about this file, see the man pages
# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).

driftfile /var/lib/ntp/drift

# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery

# Permit all access over the loopback interface.  This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1
restrict -6 ::1

# Hosts on local network are less restricted.
#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst
server time.nuri.net iburst

#broadcast 192.168.1.255 autokey    # broadcast server
#broadcastclient            # broadcast client
#broadcast 224.0.1.1 autokey        # multicast server
#multicastclient 224.0.1.1        # multicast client
#manycastserver 239.255.254.254        # manycast server

includefile /etc/ntp/crypto/pw

# Key file containing the keys and key identifiers used when operating
# with symmetric key cryptography.
keys /etc/ntp/keys

# Specify the key identifiers which are trusted.
#trustedkey 4 8 42

# Specify the key identifier to use with the ntpdc utility.
#requestkey 8

# Specify the key identifier to use with the ntpq utility.
#controlkey 8

# Enable writing of statistics records.
#statistics clockstats cryptostats loopstats peerstats

4)设置当前时区为上海

[root@localhost ~]# rm -rf /etc/localtime
[root@localhost ~]# ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

5)启动ntpd服务

[root@localhost ~]# service ntpd status
ntpd 已停
[root@localhost ~]# service ntpd start
正在启动 ntpd： [确定]
[root@localhost ~]# service ntpd status
ntpd (pid 30317) 正在运行...
[root@loahlhost ~]# chkconfig --level 2345 ntpd on

参考：linux下使用ntpdate进行时间同步

https://www.cnblogs.com/flytogalaxy/p/8471675.html

2.4、关闭selinux

1)临时关闭：

[root@localhost ~]# getenforce
Enforcing
[root@localhost ~]# setenforce 0
[root@localhost ~]# getenforce
Permissive

2)永久关闭：

[root@localhost ~]# vim /etc/sysconfig/selinux

SELINUX=enforcing 改为 SELINUX=disabled

[root@localhost ~]# cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

2.5、调整ulimit

1)查看当前限制

[root@localhost ~]# ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 63653
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 63653
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

2)临时增加系统对当前用户每个进程可以同时打开的最大文件数,可以运行的最大并发进程数( ulimit设置参考 )

[root@localhost ~]# ulimit -n 65535
[root@localhost ~]# ulimit -u 65535

3）永久修改

[root@localhost ~]# vi /etc/security/limits.conf

在文件末尾添加以下内容：

* soft noproc 65535
* hard noproc 65535
* soft nofile 65535
* hard nofile 65535

[root@localhost ~]# cat /etc/security/limits.conf
# /etc/security/limits.conf
#
#Each line describes a limit for a user in the form:
#
#<domain>        <type>  <item>  <value>
#
#Where:
#<domain> can be:
#        - a user name
#        - a group name, with @group syntax
#        - the wildcard *, for default entry
#        - the wildcard %, can be also used with %group syntax,
#                 for maxlogin limit
#
#<type> can have the two values:
#        - "soft" for enforcing the soft limits
#        - "hard" for enforcing hard limits
#
#<item> can be one of the following:
#        - core - limits the core file size (KB)
#        - data - max data size (KB)
#        - fsize - maximum filesize (KB)
#        - memlock - max locked-in-memory address space (KB)
#        - nofile - max number of open file descriptors
#        - rss - max resident set size (KB)
#        - stack - max stack size (KB)
#        - cpu - max CPU time (MIN)
#        - nproc - max number of processes
#        - as - address space limit (KB)
#        - maxlogins - max number of logins for this user
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
#        - msgqueue - max memory used by POSIX message queues (bytes)
#        - nice - max nice priority allowed to raise to values: [-20, 19]
#        - rtprio - max realtime priority
#
#<domain>      <type>  <item>         <value>
#

#*               soft    core            0
#*               hard    rss             10000
#@student        hard    nproc           20
#@faculty        soft    nproc           20
#@faculty        hard    nproc           50
#ftp             hard    nproc           0
#@student        -       maxlogins       4

* soft noproc 65535
* hard noproc 65535
* soft nofile 65535
* hard nofile 65535

# End of file

4)再次查看当前限制信息

[root@localhost ~]# ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 63653
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 65535
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 63653
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

参考：使用ulimit设置文件最大打开数

2.6、调整SSH，保持长连接

[root@localhost ~]# vi /etc/ssh/sshd_config

ClientAliveInterval 60 ＃server每隔60秒发送一次请求给client，然后client响应，从而保持连接

ClientAliveCountMax 3 ＃server发出请求后，客户端没有响应得次数达到3，就自动断开连接，正常情况下，client不会不响应

[root@localhost ~]# service sshd restart
停止 sshd：                                                [确定]
正在启动 sshd：                                            [确定]

2.7、安装crontab

[root@localhost ~]# yum install vixie-cron crontab
[root@localhost ~]# chkconfig --level 2345 crond on

2.8、安装辅助命令

[root@localhost ~]# yum install wget zip unzip lrzsz telnet

三、安装执行环境

3.1、下载JAVA JDK

[root@localhost ~]# wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "https://download.oracle.com/otn-pub/java/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/jdk-8u191-linux-x64.rpm"

#安装JAVA JDK

[root@localhost ~]# yum install jdk-8u191-linux-x64.rpm

3.2、安装MySQL

1)下载MySQL

[root@localhost ~]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-1.el6.x86_64.rpm-bundle.tar
[root@localhost ~]# tar xvf mysql-5.7.24-1.el6.x86_64.rpm-bundle.tar
[root@localhost ~]# yum install mysql-*.rpm
[root@localhost ~]# vi /etc/my.cnf

2)编辑mysql配置，在[mysqld]下面添加配置

max_connections=1000

wait_timeout=50

sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

[root@localhost ~]# cat /etc/my.cnf

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

#最大链接数
max_connections=1000
wait_timeout=50

sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

#MySQL在完成某些join（连接）需求的时候，为了减少参与join的“被驱动表”的读取次数以提高性能，
#需要使用到join buffer来协助完成join操作,当join buffer 太小，
#MySQL不会将该buffer存入磁盘文件而是先将join buffer中的结果与需求join的表进行操作，
#然后清空join buffer中的数据，继续将剩余的结果集写入次buffer中
join_buffer_size = 512M
tmp_table_size = 128M
tmpdir = /tmp

#该值设置过小将导致单个记录超过限制后写入数据库失败，且后续记录写入也将失败
max_allowed_packet = 100M

innodb_buffer_pool_size=4096M
innodb_log_file_size = 512M
#MySQL读入缓冲区的大小
read_buffer_size = 64M
#MySQL的随机读缓冲区大小
read_rnd_buffer_size = 16M
#MySQL的顺序读缓冲区大小
sort_buffer_size = 16M

#查询缓存
query_cache_size=100M
key_buffer_size=64m
thread_cache_size=64

#开启慢查询日志
slow_query_log = 1
#超出次设定值的SQL即被记录到慢查询日志
long_query_time = 6
slow_query_log_file = /var/log/mysql/slow.log
#表示记录下没有使用索引的查询
log_queries_not_using_indexes = 1

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
log-error=/var/log/mysql/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

3)启动msyql

[root@localhost ~]# service mysqld start
[root@localhost ~]# chkconfig --level 2345 mysqld on

4)查看msyql root密码

[root@localhost ~]# grep ‘temporary password‘ /var/log/mysqld.log

5)登录mysql

[root@localhost ~]# mysql -uroot -p密码

6)修改密码

mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘新密码‘;

7)编辑防火墙,开放端口3306

[root@localhost ~]# vi /etc/sysconfig/iptables

添加一条命令：

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

[root@localhost ~]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

8)重启防火墙

[root@localhost ~]# service iptables restart

3.3、安装redis

[root@localhost ~]# yum install epel-release   #添加epel源
[root@localhost ~]# yum install redis
[root@localhost ~]# service redis start
[root@localhost ~]# chkconfig --level 2345 redis on

3.4、下载Tomcat ( 官网下载地址 )

[root@localhost ~]# wget -P /home/server/tomcat8 http://mirrors.hust.edu.cn/apache/tomcat/tomcat-8/v8.5.35/bin/apache-tomcat-8.5.35.tar.gz
[root@localhost ~]# cd /home/server/tomcat8 
[root@localohst ~]# tar zxvf apache-tomcat-8.5.35.tar.gz

3.5、上传Web应用代码

上传至 /home/server/tomcat8.35/webapps/

?  ~ rsync webApllication.war root@www.xxx.com:/home/server/tomcat8.35/webapps/
[root@localohst ~]# jar xvf webApllication.war

3.6、jvisualvm远程监控tomcat

1)添加如下配置：

[root@localohst ~]# vi /home/server/tomcat8/venus_server/bin/startup.sh

SERVER_ROOT_DIR=`pwd`

export CATALINA_OPTS="$CATALINA_OPTS
-Dcom.sun.management.jmxremote

export JAVA_OPTS="$JAVA_OPTS -server -Xms6144m -Xmx6144m -XX:NewSize=1024m -XX:MaxNewSize=2048m -XX:SurvivorRatio=2 -XX:+UseParallelGC"

exec "$PRGDIR"/"$EXECUTABLE" start "$@"

2)设置远程监控账号：

[root@localhost conf]# vi /home/server/tomcat8.35/conf/jmxremote.access

内容如下：

用户名权限类型(readonly:只读，readwrite:读写)

[root@localhost conf]# cat jmxremote.access
guest readonly
root readwrite

设置远程监控密码：

用户名密码

[root@localhost conf]# vi /home/server/tomcat8.35/conf/jmxremote.password
[root@localhost conf]# cat /home/server/tomcat8.35/conf/jmxremote.password
guest xxxxxx
root  xxxxxx

3)设置文件权限

[root@localhost conf]# chmod 600 /home/server/tomcat8.35/conf/jmxremote*

4)启动web应用

[root@localhost conf]# sh /home/server/tomcat8.35/bin/startup.sh

3.7、辅助shell

1.内存监控，并回收脚本

#!/bin/bash

LIMIT=512
LOG_FILE="/var/log/timing_dropcaches.log"

#定时清理系统内存
#https://blog.csdn.net/gaojinshan/article/details/40710369
used=`free -m | awk ‘NR==2‘ | awk ‘{print $3}‘`
free=`free -m | awk ‘NR==2‘ | awk ‘{print $4}‘`

echo "===========================" >> $LOG_FILE
date +"%Y-%m-%d %H:%M.%S" >> $LOG_FILE
echo "Memory usage | [Use：${used}MB][Free：${free}MB] | [${LIMIT}]MB" >> $LOG_FILE

# drop caches when the free memory less than 2G
if [ $free -le $LIMIT ] ; then
 #sync && echo 1 > /proc/sys/vm/drop_caches
 #sync && echo 2 > /proc/sys/vm/drop_caches
 sync && echo 3 > /proc/sys/vm/drop_caches
 echo "OK" >> $LOG_FILE
else
 echo "Not required" >> $LOG_FILE
fi

2.日志清理脚本

[root@localhost ~]# crontab -e

#删除2天前的日志
/usr/bin/find /home/server/tomcat8.35 -name *.log -mtime +2 | grep `date +%Y` | xargs rm -Rf {} > /dev/null 2>&1

四、压力测试

4.1、安装Webbench

wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz
tar -zxvf ./webbench-1.5.tar.gz
yum install -y gcc ctags
cd ./webbench-1.5
make &make install
make clean

参考：webbench安装

4.2、使用说明

webbench [option]... URL
  -f|--force               Don‘t wait for reply from server.
  -r|--reload              Send reload request - Pragma: no-cache.
  -t|--time <sec>          Run benchmark for <sec> seconds. Default 30.
  -p|--proxy <server:port> Use proxy server for request.
  -c|--clients <n>         Run <n> HTTP clients at once. Default one.
  -9|--http09              Use HTTP/0.9 style requests.
  -1|--http10              Use HTTP/1.0 protocol.
  -2|--http11              Use HTTP/1.1 protocol.
  --get                    Use GET request method.
  --head                   Use HEAD request method.
  --options                Use OPTIONS request method.
  --trace                  Use TRACE request method.
  -?|-h|--help             This information.
  -V|--version             Display program version.

t是benchmark持续多久。

c是指time时间内请求多少次。

比如我们测试百度, 启动100个客户端同时请求百度首页，持续60S：

webbench -t 60 -c 100 http://www.baidu.com/

4.3、运行结果

Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software.

Benchmarking: GET http://www.baidu.com/
100 clients, running 60 sec.

Speed=2643 pages/min, 5045450 bytes/sec.
Requests: 2641 susceed, 2 failed.
