## 接着上面一篇安装准备之一 ##

## Mysql安装 ##

1. 下载 mysql-5.7.23-linux-glibc2.12-x86\_64.tar.gz

2.远程拷贝mysql-5.7.23-linux-glibc2.12-x86\_64.tar.gz到Centos机器上

3.解压缩 tar -xvf mysql-5.7.23-linux-glibc2.12-x86\_64.tar.gz

4.cp mysql-5.7.23-linux-glibc2.12-x86\_64 /usr/local/

5. cd /usr/local/

6. mv mysql-5.7.23-linux-glibc2.12-x86\_64 mysql

7. ** 添加系统mysql组和mysql用户：**

*  执行命令：groupadd mysql和useradd -r -g mysql mysql

*  创建mysql数据目录，新目录不存在则创建

数据库数据默认目录datadir=/var/lib/mysql，可通过vim /etc/my.cnf 查看

创建mysql下data目录，cd /usr/local/mysql  mkdir data

*  修改目录权限

chown -R mysql:mysql  ./

*  初始化数据库

./scripts/mysql\_install\_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

*  修改权限为root

\[root@localhost mysql\]\# chown -R root:root .

\[root@localhost mysql\]\# chown -R mysql:mysql data

*  添加启动服务
 *  \[root@localhost mysql\]\# cp support-files/mysql.server /etc/init.d/mysql
 *  \[root@localhost mysql\]\# service mysql start
 *   
 *  遇到的问题
 *  　　\[root@localhost bin\]\# ./mysql  
    　　ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
 *  解决方法
 *  \[root@localhost bin\]\# ./mysqld\_safe --user=mysql --skip-grant-tables --skip-networking &
 *  \[root@localhost bin\]\# ./mysql -u root mysql
 *  mysql> UPDATE user SET Password=PASSWORD('') where USER='root'; 
 *  mysql> FLUSH PRIVILEGES; 
 *  mysql> quit
 *  将MySQL设置默认启动项：chkconfig --add mysql
 *  查看启动项：：chkconfig --list mysql

### jenkins 安装 (这边是直接安装没有依赖tomcat) ###

1. Jenkins版本下载，这边我下载的是稳定版：

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo

2. Jenkins安装：

sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key

sudo yum install jenkins

3. 修改端口：本人一般不太喜欢用8080端口，所以修改了端口 vim  /etc/sysconfig/jenkins

4. reboot 机器

5. Service Jenkins status Error信息如下：![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3MjY4ODQx_size_27_color_FFFFFF_t_70 2][]

6. 查了一些这个问题的解决方案是找不到Java的路径，然后ln一个路径：ln -s /root/jdk1.8.0\_181/bin/java /usr/bin/java

7. 重新执行命令 service jenkins status,还是出错信息如下：jenkins.service - LSB: Jenkins Automation Server

Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)

8.尝试解决方案：vim  /etc/sysconfig/jenkins 修改 默认用户Jenkins为root如下：

9.reboot机器，启动Jenkins界面如下：

10. 到centos机器上面获得密码如下：路径就上面的图片admin路径，然后进入下个设置页面
