centos8 nginx php7.4等环境安装配置

脑子一热，把一台私人小服务器从centos6升级到8，安装php7.4尝尝鲜，没有想到费了一番事。记录如下。

1. yum 安装nginx1.14，安装php74

sudo yum install nginx
dnf -y install dnf-utils
yum search php74*
yum install php74-php

安装完成后php访问不到。后来发现以前版本php，在nginx里默认配置是：

fastcgi_pass 127.0.0.1:9000;

到php目录下查看配置：

listen = /var/opt/remi/php74/run/php-fpm/www.sock

修改nginx配置为：fastcgi_pass  /var/opt/remi/php74/run/php-fpm/www.sock;

启动还是报错，看了下nginx error log，提示为www.sock没有权限，于是给了www.sock +rw权限，成功执行！

配置nginx，同时可以访问443和80端口

#
# The default server
#

server {
    listen               80;
    listen               443 ssl;
    server_name  blog.pianhuangw.com;
    root         /data/web/blog.pianhuangw.com;
    index       index.php;

   ssl_certificate /etc/nginx/cert/blog.pianhuangw.com.pem;
   ssl_certificate_key /etc/nginx/cert/blog.pianhuangw.com.key;
   ssl_session_timeout 5m;
   ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
   ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
   ssl_prefer_server_ciphers on;

    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;

   location ~ .php$ {
        root           /data/web/blog.pianhuangw.com;
        fastcgi_pass   unix:/var/opt/remi/php74/run/php-fpm/www.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    error_page 404 /404.html;
        location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }

}

2. php74 mysql扩展

yum install php74-php-mysqlnd.x86_64

3. mysql56安装

这个是用rpm包装的

rpm -ivh MySQL-server-5.6.19-1.el6.x86_64.rpm 
rpm -ivh MySQL-devel-5.6.36-1.el6.x86_64.rpm 
rpm -ivh MySQL-client-5.6.36-1.el6.x86_64.rpm

mysql 默认生成的密码在/root/.mysql_secret，查看密码后登录：

mysql -uroot -p
# 修改root默认密码
SET PASSWORD=PASSWORD('123456');

4. java1.8安装

这个也是rpm包，就比较简单了

rpm -ivh jdk-8u192-linux-x64.rpm 

配置环境变量

vim /etc/profile

JAVA_HOME=/usr/java/jdk1.8.0_192-amd64
JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export JAVA_HOME JRE_HOME PATH CLASSPATH

source /etc/profile生效

可以echo $JAVA_HOME看下路径，java -version，javac验证下。

5. docker安装

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
#这一步是因为centos8下会提示containerd.io>1.2.2版本
yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm
yum install -y docker-ce

docker version验证安装成功。

6. consul安装

./consul agent -server -ui -bootstrap-expect 1 -client 0.0.0.0 -config-dir /data/app/consul/config.json -data-dir /data/app/consul/data1/

consul.json配置如下:

{
        "datacenter": "zyproject-dc",
        "node_name": "zyproject-reg1",
        "data_dir": "/data/app/consul/data1",
        "ports": {
                "http": 8000,
                "dns": 8601,
                "grpc": 8401,
                "serf_lan": 8311,
                "server": 8310
        }
}

再启一个client模拟集群

./consul agent -data-dir=/data/app/consul/data2 -advertise=127.0.0.1 -client=0.0.0.0 -join=127.0.0.1:8311 -datacenter='zyproject-dc'
