CentOS+Nginx+Tomcat+Mysql+PHP

Posted 2021-09-15 ankey

一、安装centos 7.0

二、关闭不需要的安全设置，使用其他的安全管理

sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
setenforce 0

systemctl stop firewalld    //停止系统默认的防火墙
systemctl mask firewalld   //屏蔽服务(让它不能启动)

三、CentOS7彻底关闭IPV6

编辑/etc/default/grub，在GRUB_CMDLINE_LINUX加上的后面句首加上ipv6.disable=1
修改前:

[root@localhost Desktop]# cat /etc/default/grub 
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed \'s, release .*$,,g\' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

修改后:

[root@localhost Desktop]# cat /etc/default/grub 
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed \'s, release .*$,,g\' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="ipv6.disable=1 rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

修改完毕后保存，运行grub2-mkconfig -o /boot/grub2/grub.cfg重新生成grub.cfg文件

[root@localhost Desktop]# grub2-mkconfig -o /boot/grub2/grub.cfg 
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.10.0-514.2.2.el7.x86_64

Found initrd image: /boot/initramfs-0-rescue-d885883cdb4944609bc5e3493dd2b680.img
done

重启系统，运行lsmod|grep ipv6，可以看到ipv6已经关闭。

reboot    //重启让selinux、IPv6等配置生效

四、管理工具安装

安装ifconfig、ntsysv、updatedb、lrzsz(上传下载)、wget(远程http下载)功能

yum install -y chkconfig  net-tools telnet ntsysv mlocate lrzsz wget lsof setuptool tcpdump
yum install -y system-config-securitylevel-tui system-config-network-gui system-config-network-tui system-config-date
yum install -y vim nano             //安装编辑器

五、更新Centos 7.0 repo源

yum install -y epel-release
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
rpm  -Uvh  http://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm  -Uvh  http://mirror.webtatic.com/yum/el7/webtatic-release.rpm

5.1、CentOS 7阿里云源

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
yum install -y python-pip
pip install --upgrade pip
pip install requests

5.2、安装nginx yum安装的第三方repo源文件(使用编译安装则不需要)

mkdir /root/software
cd /root/software
wget https://mirrors.ustc.edu.cn/epel/7/x86_64/Packages/e/epel-release-7-12.noarch.rpm
rpm -ivh epel-release-7-12.noarch.rpm
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

5.3、安装mysql yum安装的第三方repo源文件(使用编译安装则不需要)

cd /root/software   //进入源文件集中文件夹
wget https://repo.mysql.com/mysql57-community-release-el7-11.noarch.rpm  //下载
yum localinstall -y mysql57-community-release-el7-11.noarch.rpm   //通过rpm安装得到repo源
yum repolist enabled | grep "mysql.*-community.*"    //检查mysql源是否安装成功

六、环境安装

现在开始正式配置各种应用环境。

6.1 环境的预装

yum install -y make cmake gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers  gd gd-devel perl expat expat-devel nss_ldap unixODBC-devel libxslt-devel libevent-devel libtool-ltdl bison libtool zip unzip gmp-devel pcre pcre-devel python-devel  perl-devel perl-ExtUtils-Embed  //安装各种环境所需要的插件
yum update -y    //升级补丁

6.2 安装iptables(可不安装)

yum install -y iptables-services  //安装iptables
systemctl enable iptables    //开机自启动
service iptables start    //启动服务
iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT //允许远程访问mysql
iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT //允许远程访问http
iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 443 -j ACCEPT //允许远程访问https
service iptables save   //保存相关操作配置
systemctl stop iptables.service   //关闭iptables服务

设置iptables规则

6.2.1 清除所有规则，所有设置从头开始

iptables -F        //清除预设表filter中的所有规则链的规则
iptables -X        //清除预设表filter中使用者自定链中的规则
service iptables save     //保存结果，否则重启后又恢复原来的状态

查询结果：

iptables -L -n
Chain INPUT (policy ACCEPT)
target       prot opt source                 destination         
Chain FORWARD (policy ACCEPT)
target       prot opt source                 destination         
Chain OUTPUT (policy ACCEPT)
target       prot opt source                 destination    `

6.2.2 设定预设规则

iptables -A INPUT -p tcp --dport 22 -j ACCEPT   //允许所有IP，访问22端口(流入)
iptables -A OUTPUT -p tcp --sport 22 -j ACCEPT  //允许所有IP，访问22端口(流出)
iptables -I INPUT -s 10.17.162.137 -p tcp --dport 22 -j ACCEPT  //指定IP访问指定端口
iptables -I OUTPUT -s 10.17.162.137 -p tcp --sport 22 -j ACCEPT  //若流出被禁止，则需要追加该条规则

[client]
default-character-set=utf8
socket=/var/lib/mysql/mysql.sock

[mysqld_safe]
open-files-limit = 8192
log-error=/var/log/mysqld.log
socket=/var/lib/mysql/mysql.sock
pid-file=/var/run/mysqld/mysqld.pid

service mysqld restart //重启mysql

##### MySQL运维小知识
MySQL高占用CPU、内存，有可能是由于进程未能及时释放，可以通过简单的设置，可以有效的解决这个问题。

mysql -uroot -p
mysql> show global variables like \'%timeout\';
mysql> set global interactive_timeout=100;

> 段落引用上述的，在重启mysqld.service后失效

vi /etc/my.cnf
[mysqld]
interactive_timeout=20
wait_timeout=20

> 段落引用上述，任何时候都生效
##### mysql创建远程用户并授权，尽量不建议，因为这样不安全

mysql -uroot -p
mysql> create user root identified by \'Jeson.123.com\';
mysql> grant all privileges on . to \'root\'@\'%\'identified by \'Jeson.123.com\' with grant option;
mysql> flush privileges;

##### mysql创建数据库

mysql> CREATE DATABASE lottery DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

##### mysql修改指定用户的密码

update mysql.user set password=password(\'新密码\') where User="test" and Host="localhost";

##### mysql删除指定用户

delete from user where User=\'test\' and Host=\'localhost\';

#### 6.4、安装php环境

yum install -y php56w php56w-cli php56w-common php56w-gd php56w-ldap php56w-mbstring php56w-mcrypt php56w-mysql php56w-pdo php56w-devel
yum install -y traceroute net-snmp-devel vim sysstat tree mysql-devel ntpdate libjpeg* bind-utils
yum install -y php56w-imap php56w-odbc php56w-pear php56w-xml php56w-xmlrpc php56w-mhash libmcrypt php56w-bcmath
yum install -y php56w-fpm

vi /etc/php-fpm.d/www.conf

user = nginx //默认为apache，修改与nginx一致的用户 需要安装nginx后才能改
group = nginx //默认为apache，修改与nginx一致的组 需要安装nginx后才能改

vi /etc/php.ini

session.save_path = "/var/lib/php/session" //设置session的位置，否则PHP运行会出错

chmod 777 /var/lib/php/session //设置文件夹属性
chkconfig php-fpm on

#### 6.5、安装 REDIS 及 REDIS-php 服务

yum install -y tcl //若不安装tcl，在make test时会出现错误

cd /usr/local/src
wget http://download.redis.io/releases/redis-4.0.9.tar.gz //下载redis安装包
tar zxvf redis-4.0.9.tar.gz //解压

cd redis-4.0.9 //进入redis安装文件夹中，该文件为二进制文件，可直接make操作。
make distclean //清理旧的一些编译过的文件
make
make test
make PREFIX=/opt/redis USE_TCMALLOC=yes install
mkdir -p /opt/redis/etc
mkdir -p /opt/redis/run
mkdir -p /opt/redis/data/6379
mkdir -p /opt/redis/log
cp redis.conf /opt/redis/etc/redis.conf
cp /opt/redis/etc/redis.conf /opt/redis/etc/redis_6379.conf

##### 创建自动启动脚本

touch /etc/init.d/redis
vi /etc/init.d/redis

> 段落引用内容如下：

#!/bin/sh
#chkconfig: 2345 80 90

Simple Redis init.d script conceived to work on Linux systems

as it does use of the /proc filesystem.

PATH="/opt/redis/bin:$PATH"
EXEC="/opt/redis/bin/redis-server"
CLIEXEC="/opt/redis/bin/redis-cli"
PIDFILE="/opt/redis/run/redis_6379.pid"
CONF="/opt/redis/etc/redis_6379.conf"
PORT="6379"

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
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running."
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$CLIEXEC -p $PORT shutdown
while [ -x /proc/${PID} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped."
fi
;;
restart)
$0 stop && $0 start
;;
*)
echo "Usage: $0 {start|stop|restart}" >&2
exit 1
;;
esac

> 赋予运行权限

chmod +x /etc/init.d/redis

##### 修改时区

vi /etc/php.ini

date.timezone = Asia/Shanghai

##### 修改redis配置

cp -r src/redis-* /opt/redis/
cd /opt/redis/
./redis-server etc/redis.conf
vi /opt/redis/etc/redis.conf

daemonize no ==> daemonize yes

##### 安装phpredis

cd /root/software
git clone https://github.com/phpredis/phpredis.git

cd phpredis
phpize
./configure --with-php-config=php-config
make
make test
make install

##### 让PHP支持调用redis

vi /etc/php.ini

> 在最后面增加以下内容

[redis]
extension = /usr/lib64/php/modules/redis.so

> 添加到自动启动项中

chkconfig --add redis //开机自启动

#### 6.6、YAF编译安装

cd /root/software
wget http://pecl.php.net/get/yaf-2.3.5.tgz //需与PHP(5.6)版本匹配
tar zxvf yaf-2.3.5.tgz

##### 安装yaf

cd yaf-2.3.5
phpize
./configure --with-php-config=/usr/bin/php-config
make
make test
make install

##### 让PHP支持调用Yaf

vi /etc/php.ini

> 在最后面增加以下内容

[Yaf]
extension=/usr/lib64/php/modules/yaf.so
yaf.use_namespace = 1
yaf.environ = "develop"

##### 测试是否成功

php -i | grep yaf

> 出现下面这些内容，说明安装成功

yaf
yaf support => enabled
Supports => http://pecl.php.net/package/yaf
yaf.action_prefer => Off => Off
yaf.cache_config => Off => Off
yaf.environ => develop => develop

#### 6.7、安装nginx

yum install -y automake autoconf libtool make
yum install -y nginx
chkconfig nginx on

##### 配置虚拟机

cd /etc/nginx
mkdir vhost //放虚拟主机配置文件的位置

vi nginx.conf

> 在server{}中添加如下内容
> 在server的root下添加如下内容，默认首页文件名

index index.php default.php index.html index.htm;

> 在server中添加支持PHP的语句

    location ~ .php$ {
        root html;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

> 在http{}的最后，添加如下内容

include vhost/*.conf;        //添加完成后保存退出

##### 检查配置结果

nginx -t //检查nginx.conf及vhost下的配置文件是否正确
service php-fpm start //启动PHP-FPM
service nginx restart //重启nginx服务

##### 虚拟主机配置示例

server {
listen 808;
server_name 10.17.162.113:808;

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" />
-->

##### 修改为：

<Connector port="8443"
protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150" 
SSLEnabled="true"
scheme="https"
secure="true"
keystoreFile="/opt/tomcat/huizhong/conf/cert/201802031124.pfx"    //绝对路径，否则容易出错
keystoreType="PKCS12"
keystorePass="201802031124"
clientAuth="false"
SSLProtocol="TLSv1+TLSv1.1+TLSv1.2"
ciphers="TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA256"/>

##### 并新加节点：

<Valve className="org.apache.catalina.valves.RemoteIpValve"
remoteIpHeader="x-forwarded-for"
remoteIpProxiesHeader="x-forwarded-by"
protocolHeader="x-forwarded-proto"/>

##### 重启tomcat服务

systemctl restart tomcat.service

> 注：没有若只有key及crt文件的证书，可以进入
https://www.myssl.cn/tools/merge-pfx-cert.html
中进行生成一个pfx文件的证书，并设置一个密码。

##### 通过VisualVM对Tomcat性能监控
> JMX下载地址：http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.81/bin/extras/catalina-jmx-remote.jar
catalina-jmx-remote.jar包下载完成后放到Tomcat的lib目录下

vim catalina.sh

> 在注释下面添加如下内容

CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=7090
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=被监控的服务器IP地址
-Dcom.sun.management.jmxremote.authenticate=true
-Dcom.sun.management.jmxremote.password.file=/var/tomcat/tomcat7/conf/jmxremote.password
-Dcom.sun.management.jmxremote.access.file=/var/tomcat/tomcat7/conf/jmxremote.access"

cd /var/tomcat/tomcat7/conf
vim jmxremote.access

monitorRole readonly
controlRole readwrite

vim jmxremote.password //要与运行tomcat的权限一致

monitorRole 25DWdl2&D^W
controlRole 25DWdl2&D^W

##### 赋权及重启Tomcat

chmod 0400 jmxremote.password //密码文件应该是只读的，只能由Tomcat运行用户
systemctl restart tomcat.service

至此，一个完整的环境就配置完成了。
